Our initial findings show that the more timely Estimize forecasts provide greater short-term accuracy when compared to IBES. We find Estimize is more accurate than IBES for estimates taken one-week before the announcement date. We find that the timelier Estimize forecasts can more accurately identify earnings surprise which results in a greater capture of the post earnings drift. We use this finding to construct a daily trading strategy that goes long the stocks that beat the Estimize consensus and short the stocks that miss.
"Quantitative Trading as a Mathematical Science" by Dr. Haksun Li, Founder an...Quantopian
Presented at QuantCon Singapore 2016, Quantopian's quantitative finance and algorithmic trading conference, November 11th.
Quantitative trading is distinguishable from other trading methodologies like technical analysis and analysts’ opinions because it uniquely provides justifications to trading strategies using mathematical reasoning. Put differently, quantitative trading is a science that trading strategies are proven statistically profitable or even optimal under certain assumptions. There are properties about strategies that we can deduce before betting the first $1, such as P&L distribution and risks. There are exact explanations to the success and failure of strategies, such as choice of parameters. There are ways to iteratively improve strategies based on experiences of live trading, such as making more realistic assumptions. These are all made possible only in quantitative trading because we have assumptions, models and rigorous mathematical analysis.
Quantitative trading has proved itself to be a significant driver of mathematical innovations, especially in the areas of stochastic analysis and PDE-theory. For instances, we can compute the optimal timings to follow the market by solving a pair of coupled Hamilton–Jacobi–Bellman equations; we can construct sparse mean reverting baskets by solving semi-definite optimization problems with cardinality constraints and can optimally trade these baskets by solving stochastic control problems; we can identify statistical arbitrage opportunities by analyzing the volatility process of a stochastic asset at different frequencies; we can compute the optimal placements of market and limit orders by solving combined singular and impulse control problems which leads to novel and difficult to solve quasi-variational inequalities.

Presented at QuantCon Singapore 2016, Quantopian's quantitative finance and algorithmic trading conference, November 11th.
Even with a wide range of statistical tools available, selection of algorithmic trading strategies can
leave the trader with significant out-of-sample variability. In most cases the final decision making
is still a manual process.
This presentation will show how a combination of statistical methods and machine learning can help to automate strategy selection and boost the robustness of automated trading systems.

A Guided Tour of Machine Learning for Traders by Tucker Balch at QuantCon 2016Quantopian
You’ve probably heard about Machine Learning and you likely know it is of emerging importance for trading and investing. Unfortunately it is a deeply technical field and the complexity and jargon get in the way of broader use and understanding. There are literally hundreds of learning algorithms that each solve a slightly different problem. Which algorithms really matter for investing? In this presentation, Professor Balch will help declutter the ML jungle. He’ll introduce a few of the most important ML algorithms and show how they can be applied to the challenges of trading.
This presentation demonstrates that how economic concepts and/or econometric techniques can be useful in financial decision making (i.e. trading) and that how EViews can effectively handle the whole process.
Quant trading with artificial intelligenceRoger Lee, CFA
Foster discussion on the practical approach of applying artificial intelligence (AI) in quant trading and avoiding the common pitfalls and the opportunities and future of quant trading.
Financial trading is the space in which people have to make decisions under uncertain uncertainty and requires decisions to be explained. However, most AI algorithm (e.g. neural network) are black-box and serves well under only constrained environment (e.g. Go / Atari). Therefore, it is important to gather domain knowledge such that AI (e.g. PGM) could have more cognitive ability to provide a white-box explanation for their trading decisions.
If AI could provide a clearer visibility on the reality & present, it can assist human to provide faster, more-accurate and more-informed investment decisions. With a better understanding of the world, we can allocate resources more efficiently and ultimately create a better world to live.

Introduction
This report presents my research work carried out at Credit Suisse from May to September 2012. This study has been pursued in collaboration with the Global Arbitrage Strategies team.
Quantitative analysis strategy developers use sophisticated statistical and optimization techniques to discover and construct new algorithms. These algorithms take advantage of the short term deviation from the ”fair” securities’ prices. Pairs trading is one such quantitative strategy - it is a process of identifying securities that generally move together but are currently ”drifting away”.
Pairs trading is a common strategy among many hedge funds and banks. However, there is not a significant amount of academic literature devoted to it due to its proprietary nature. For a review of some of the existing academic models, see [6], [8], [11] .
Our focus for this analysis is the study of two quantitative approaches to the problem of pairs trading, the first one uses the properties of co-integrated financial time series as a basis for trading strategy, in the second one we model the log-relationship between a pair of stock prices as an Ornstein-Uhlenbeck process and use this to formulate a portfolio optimization based stochastic control problem.
This study was performed to show that under certain assumptions the two approaches are equivalent.
Practitioners most often use a fundamentally driven approach, analyzing the performance of stocks around a market event and implement strategies using back-tested trading levels.
We also study an example of a fundamentally driven strategy, using market reaction to a stock being dropped or added to the MSCI World Standard, as a signal for a pair trading strategy on those stocks once their inclusion/exclusion has been made effective.
This report is organized as follows. Section 1 provides some background on pairs trading strategy. The theoretical results are described in Section 2. Section 3
"Portfolio Optimisation When You Don’t Know the Future (or the Past)" by Rob...Quantopian
We generally assume the past is a good guide to the future, but well do we even know the past? What effect does this uncertainty when estimating inputs have on the notoriously unstable algorithms for portfolio optimization?
I explore this issue, look at some commonly used solutions, and also introduce some alternative methods.
This presentation provide a general overview on Algorithmic trading. It has basic definitions and some details on general aspect of the environment in which algo trading is used.
"From Trading Strategy to Becoming an Industry Professional – How to Break in...Quantopian
You have created a great trading strategy, backtested, traded it and now you want to take it to the next level. You may find that developing the strategy was just the first of many difficult steps.
With the increased availability of low cost, high quality quant modelling platforms, the field is much more open than it once was. The interest for algorithmic trading his higher than ever and anyone has the potential develop a great trading model.
But having a great trading model is not enough. The work is not done yet.
This presentation will discuss turning your algorithmic trading strategy into a business or a great job, and becoming a professional trader. We’re going to talk about what it takes to move to the next level and where the common pitfalls lay. What kind of strategies are marketable are which are not. The pros and cons of trading your own money and how to go about finding external capital and gaining traction in the business.
Are you ready to take the step?

"From Alpha Discovery to Portfolio Construction: Pitfalls and Solutions" by D...Quantopian
From QuantCon 2017: Implementation is the efficient translation of alpha research into portfolios. It includes portfolio construction and trading. It is a vital step in the quant equity workflow, as poor implementation can ruin even the best alpha ideas. Two crucial challenges must be solved: how to construct a portfolio that most efficiently captures a given alpha signal; and, in the presence of multiple signals, how to optimally combine them into a single composite alpha factor.
This talk addresses these challenges, examines common pitfalls in the implementation of quantitative strategies and good practices to avoid them. A common theme is striking the right balance between factor signal purity and investability. We look at how factor models and optimisation techniques help professional investors answer three key questions:
· What risks should your risk model be cognisant of?
· What objective function should you use?
· What effect do investability constraints have on your portfolio?
The presentation I gave in my investment class about paris trading. I implemented a experiment using R language to identify good pairs from S&P 100 universe. The algorithm is to perform ADF test on the spread of two random stocks and find out the pairs with stationary spread (co-integrated pairs). Pairs identification period is from 2010/11 to 2012/10, test period is from 2012/11 to 2013/12. Finally I got 33 pairs out of 4950 candidates, and I conduct a summary on the experiment result.

Market Timing, Big Data, and Machine Learning by Xiao Qiao at QuantCon 2016Quantopian
Return predictability has been a controversial topic in finance for a long time. We show there is substantial predictive power in combining forecasting variables. We apply correlation screening to combine twenty variables that have been proposed in the return predictability literature, and demonstrate forecasting power at a six-month horizon. We illustrate the economic significance of return predictability through a simulation which takes positions in SPY proportional to the model forecast.
The simulated strategy yields annual returns more than twice that of the buy-and-hold strategy, with a Sharpe ratio four times as large. This application of big data ideas to return predictability serves to shift the sentiment associated with market timing.
This months speaker is Quantitative Researcher Yann-Shin Aaron Chen. Chen grew up in Taipei and moved to Southern California when he was a teenager. He participated in numerous math and physics competitions in high school and was ranked in the top 24 students in the US Physics Olympiad. He obtained a B.A. in mathematics at U.C. Berkeley, and got his PhD also at Berkeley in 2012. During his graduate studies, he did a summer internship at Morgan Stanley. After graduation, he joined Citadel, one of the largest hedge funds in US, as a quantitative researcher and worked there for 5 years. He left Citadel a few months ago, and he is now looking forward to his next venture.
Quantitative trading is a relatively new field in the world of finance. With the advances of information technology and data science, quantitative trading has generated significant interest in the past decade. In his talk, Aaron will cover the basic facts about quantitative trading and open the floor for questions. This short presentation is intended for people that are not in this industry and want to learn more about it.

Market Timing, Big Data, and Machine Learning by Xiao Qiao at QuantCon 2016Quantopian
Return predictability has been a controversial topic in finance for a long time. We show there is substantial predictive power in combining forecasting variables. We apply correlation screening to combine twenty variables that have been proposed in the return predictability literature, and demonstrate forecasting power at a six-month horizon. We illustrate the economic significance of return predictability through a simulation which takes positions in SPY proportional to the model forecast.
The simulated strategy yields annual returns more than twice that of the buy-and-hold strategy, with a Sharpe ratio four times as large. This application of big data ideas to return predictability serves to shift the sentiment associated with market timing.

What website can I sell pi coins securely.DOT TECH
Currently there are no website or exchange that allow buying or selling of pi coins..
But you can still easily sell pi coins, by reselling it to exchanges/crypto whales interested in holding thousands of pi coins before the mainnet launch.
Who is a pi merchant?
A pi merchant is someone who buys pi coins from miners and resell to these crypto whales and holders of pi..
This is because pi network is not doing any pre-sale. The only way exchanges can get pi is by buying from miners and pi merchants stands in between the miners and the exchanges.

In this report we present our latest quantitative forecasts for the coming
month. Our models are designed to generate both bottom-up stock selection
ideas as well as top-down asset, country, and style allocation calls.
Introducing the crowdsourcing dataset Estimize
Estimize is an online community that allows different types of investors to
contribute their financial forecasts. The contributors include the buy side
investment professionals, individual traders, independent researchers and
students. The merit of the Estimize dataset is based on the diverse group of
contributors and the wisdom of the crowd.
More accurate short-term earnings estimates
Our initial findings show that the more timely Estimize forecasts provide
greater short-term accuracy when compared to IBES, while IBES estimates do
a better job for longer-term forecasts. Specifically, we find Estimize is more
accurate than IBES for estimates taken one-week before the announcement
date, while the sell-side estimates from IBES show greater accuracy for
estimates collected one-month prior to announcement.
Post earnings drift and a corresponding trading strategy
We find that the timelier Estimize forecasts can more accurately identify
earnings surprise which results in a greater capture of the post earnings drift.
We use this finding to construct a daily trading strategy that goes long the
stocks that beat the Estimize consensus and short the stocks that miss.

Crowdsourcing earnings
estimates
Introducing the Estimize dataset
Earnings estimates are one of the most widely used financial metrics. They are a
measure of expected company performance and play an important role in many equity
investors’ stock selection strategies. Traditionally, earnings estimates are gathered from
sell-side analysts at institutional brokers and independent research firms. Data vendors
such as Institutional Brokers’ Estimate System (IBES) aggregate these estimates and
offer daily or monthly updates as well as historical datasets. While there are many data
vendors that aggregate sell-side earnings estimates, we have yet to find a reputable
database that collects estimates from buy-side analysts and other types of investors.
In this report, we analyze a new database from the crowdsourced community Estimize
that collects earnings and revenue forecasts from various different types of investors. It
was established in 2011 and has grown rapidly to cover more than 900 US stocks.
What sets it apart is that the community of contributors is varied, ranging across buy-
side investment professions, individual traders, independent researchers and students.
Figure 1 shows the types of the contributors to the database.

Estimize allows individuals to contribute their estimates anonymously. The underlying
concept of the community is to capture the “wisdom of the crowds” in order to reflect
investor sentiment and more timely and accurate earnings forecasts. The data structure
consists of two main parts: estimates and contributors. The estimates are made up of
EPS and revenue forecasts across each individual contributor. The data includes the
contributor’s unique ID, a timestamp for which the estimates were created and the
corresponding fiscal quarter of the forecasts. Most estimates cover the current quarter
(FQ1), but the platform allows for estimates up to the fourth fiscal quarter (FQ4). Each
contributor is assigned a unique ID which makes it possible to track the accuracy for
each individual.
Figure 2 shows the percentage of estimates made within one day, one week (including
the first day), one month and one quarter before the earnings announcement. The chart
shows that 40% of the estimates are made within 24 hours of the announcement, and
the majority of the estimates are made within one week. Few estimates are made a
quarter earlier. This is quite different from IBES, where most of the estimates are
entered at least one-month in advance, lending itself more useful to longer horizon
investors.

Who’s contributing?
Figure 3 shows that more than two-thirds of the estimates are collected from non
financial professionals. Among the financial professionals, half are independent
researchers and the other half are split evenly between buy-side and sell-side analysts.
The sample data shows that the data covers a diverse range of investors and the
information should be complementary to the traditional institutional data sources such as
IBES.

Unfortunately, as is the case with many of the newer and unique data sources, the
history of the Estimize dataset is relatively short and coverage is less extensive than
that of traditional sell-side estimate databases such as IBES.
In this report, we focus in most part on the EPS estimates from Estimize and begin our
analysis in 2012 since much of the data prior to that is too sparse.
Figure 4 shows the number of stocks covered in the Estimize database that are
members of the Russell 3000 universe. Coverage is defined by the number of unique
tickers which have at least one estimate on some day in a current fiscal quarter during
that month; regardless of whether or not the company reports during that month.
We find a strong seasonal component in the data due to earnings seasons and the fact
that most estimates are not contributed until one week before the actual announcement
(Figure 2). In addition, stock coverage drops quickly as we increase the number of
required contributors.

Figure 5 shows the median, 25th percentile, and 75th percentile of the market cap
covered by Estimize over time. The coverage consists mainly of large and midcap US
stocks and the distribution of market cap shows to be steady over the sample.
Figure 6 shows the median market cap of the stocks covered by Estimize across
different numbers of contributor (analyst) coverage. As expected, we find that larger
cap stocks which demand more attention are covered by a larger number of
contributors. This is consistent with the traditional institutional databases in that larger
cap companies will have more analyst coverage.

Gauging the accuracy of crowdsourcing?
Comparing estimates
The first question we must address is how it compares to traditional sell-side estimate
data covered by vendors such as IBES. Can it add value beyond these long existing sell
side analyst forecasts?
To get a sense of the accuracy, we compare the last Estimize EPS forecasts with those
from the daily IBES database for stocks that are available in both datasets. We begin by
comparing the average EPS estimates in each database with actual EPS reported on the
announcement date. Figure 7 shows that over the sample, the average estimate across
the Estimize database was closer to the reported number when compared to the IBES
average estimate. In addition, as the Estimize coverage increases, the forecast accuracy
relative to IBES also increases. EPS estimates for stocks with greater than 20 analysts
covering them in Estimize are more accurate 2/3 of the time.

However, the greater accuracy of Estimize database is in most part due to its timely
updating. Recall that most Estimize estimates are entered a few days prior to the
earnings announcement (Figure 2), while most IBES estimates are entered several
weeks in advance. For a more apples-to-apples comparison, we compare the estimates
at different horizons.
Figure 8 shows the accuracy of the average estimates at various windows before the
announcement date. The results show that one week before announcement the
accuracy across Estimize and IBES is similar. However, when looking at a one-month
window, IBES estimates tend to be more accurate than those in Estimize. This suggest
that sell-side analysts do a better job at predicting earnings over a longer window while
the more timely Estimize data tends to be more accurate within one week of the
announcement.

Professionals vs. non professionals
We further compare the EPS prediction accuracy of finance professionals with non-
professionals to see if the professionals make more accurate predictions. To our
surprise, the data shows that finance professionals slightly underperform non-
professionals (see Figure 9); albeit the difference is too small to make any significant or
sweeping conclusions. One explanation may be that it is due to selection bias in the
Estimize database – i.e. the more accurate professionals do not contribute their
estimates to the database.
We can also compare the accuracy of the estimates from non-professionals to those of
the combination of professionals and non-professionals (see Figure 10). The results show
that there is kind of diversification effect in that combining the two actually results in
better accuracy than any of two individually.

Buy-side vs. sell-side
Recall there is approximately the same number of estimates from buy-side and sell-side
professionals in the Estimize database (see Figure 3). We next investigate whether there
is a significant difference between these two categories in the database. Figure 11 shows
that average estimates for buy-side professions are more accurate than those from the
sell-side in the Estimize dataset. However, due to the limited sample size in the Estimize
buy side and sell side estimates (Estimize started to label the buy side and sell side
8. 4 March 2014
The Quant View
Page 8 Deutsche Bank Securities Inc.
estimates start in 2013), it may not be statistically significant to make a definite
conclusion. Similar to the results from professionals versus non-professionals above,
this result could be due to selection bias in that the more accurate sell-side analysts are
not contributing their estimates to the database. Nonetheless, Figure 12 shows that
combining the sell-side and buy-side estimates actually increases accuracy suggesting
a sort of diversification benefit from including both types of professionals in the
Estimize database.

Figure 13 further compares the difference between Estimize sell side and the IBES sell
side. The results show that IBES sell-side estimates are more accurate than those from
Estimize, which lends some credence to our hypothesis that Estimize sell-side data may
have a level of selection bias. In Figure 14, the performance for IBES sell side compared
with buy side estimates are similar as the sell side compared with buy side in Figure 11.
This is as we expected, since IBES are mostly sell side analysts estimates, so they
should have some similarity with the sell side estimates from Estimize.

Post earnings announcement surprise
Post earnings drift is the return following an earnings announcement that is attributable
to surprise. Typically, companies who beat earnings consensus tend to outperform the
market over subsequent trading while stocks that miss expectations tend to
underperform the market.
9. 4 March 2014
The Quant View
Deutsche Bank Securities Inc. Page 9
To analyze the post earnings drift in both the IBES and Estimize datasets we use an
event study. The day one return of the post earnings announcement is calculated using
the open to close price if the earnings was announce before the market opens; and use
next day open to close if the earnings was announce after the market close. The
following day’s returns are all calculated using close to close price returns. The S&P
500 total return index is used as the market return
Figure 15 and Figure 16 show the average excess return to the market for earnings
surprises greater than 10% for both Estimize and IBES estimates. In both cases the
more timely Estimize estimates shows bigger post announcement drift for both beats
and misses. However, in both cases, the cumulative excess return flattens out quickly
after the a few days, due to market efficiency.

Portfolios based on more accurate earnings estimates
Based on the event study from previous session, we would like to examine the
performance of a portfolio based on the same logic: long stocks that beat consensus
and short the stocks that miss.
As we already saw in Figure 15 and Figure 16, the earnings drift occurs mostly during
the first day of trading after the announcement. For simplicity and illustrative purposes,
we construct this portfolio with a one-day holding period, using the open price to close
price (because the earnings announcements almost always occurs after the market
close). We use SP 500 to hedge when there is no holding in one of the two legs. We
call this the Estimize earnings surprise strategy.
Turnover for this strategy is high because the portfolio changes nearly every time it is
traded. Figure 17 shows the wealth curve for this strategy under different levels of
transaction cost. Naturally, the performance drops quickly as we increase transaction
costs. However, even when transaction costs are 15 bps, the net performance is still
attractive.

We compared the same strategy based on the same earnings surprise measure using
the IBES estimates. Figure 18 show the annualized returns and Figure 19 shows the
Sharpe ratio of the two strategies under different transaction costs. For both strategies,
the performance decreases quickly as transaction costs increase. When transaction
cost increases to 10 bps per trade, the performance of the IBES earning surprise
strategy is nearly zero, and it turns negative once we have t-costs increased to 15bps.
In contrast, the Estimize earnings surprise strategy, shows an annualized return of 12%
under the 15bps t-cost scenario.

In conclusion we found multiple benefits to using the Estimize dataset; especially in the
case of short-term applications in which accuracy is essential. Another interesting
byproduct of the analysis was the power of crowdsourcing. We found that some of the
value-added in the Estimize dataset was due to the “wisdom of crowds” effect as more
predictions give way to greater accuracy. Moreover, the diversity of the contributors
provides a greater spectrum of information which can potentially improve investment
strategies based on estimates.
We should also be aware of the potential issues with the Estimize dataset. The main
issue rests on the thin coverage and the short-term nature of the forecasts; especially
when compared to commonly used sell-side estimates data. Also, the short history will
pose a problem when trying to analyze the data across different market and economic
environments.

Macro update
Turning our attention to the bigger picture, we also take the opportunity to update our
favorite top-down market indicators.
Our favorite market timing indicator
Our Variance Risk Premium (VRP) indicator is a contrarian indicator that measures
market overreaction and underreaction to realized risk. In simple terms, VRP is the
difference between options-implied risk (i.e. the VIX index) and realized risk (i.e. the
actual risk in the market measured historically over the last month). If VRP is high, we
see this as a buying opportunity for risky assets, like equities and high yield bonds.
Why? The intuition is as follows. When VRP is high, VIX has typically shot up
dramatically (i.e. the market is in panic mode). At the same time, realized risk has
probably also risen, but not to the same extent. In other words, the market has
overreacted relative to what the actual, realized data is telling us. Our research shows
that such episodes are good buying opportunities for risky assets on about a three
month horizon. On the other hand, when VRP is low, it tends to be a complacency
indicator: investors are failing to price in rising realized risk in the market, and as a
result we should be selling risky assets like equities.
Our Variance Risk Premium (VRP) indicator is a contrarian indicator that measures
market overreaction and underreaction to realized risk. Today our VRP indicator is
reading 9.1, compared to a long-term average of 14.2. Generally we pay attention to the
VRP when it hits extreme levels (like +/- 2 standard deviations).

The opportunity set for investors
Another metric we keep a close eye on is the so-called “opportunity set” for investors.
Think of this as the total alpha on the table. Our main interest is to understand what is
driving that opportunity, because this can allow us to position our strategies to pick in
the orchard with the juiciest fruit. In Figure 22 we show the opportunity set for global
equity investors, and in Figure 23 we show the same thing for emerging market equity
investors.

The key result is the size of the blue portion relative to the other colors. The blue
represents the opportunity explained by stock selection, whereas we can think of the
other colors as representing the opportunity from top-down calls like picking the right
countries, industries, and styles. When the financial crisis exploded in 2008, we moved
into a much more macro-dominated world. As a result, the portion of overall
opportunity that could be explained by individual company characteristics (e.g.
valuation, growth profile, earnings quality, etc.) shrunk sharply; no one cared if a stock
looked good on fundamentals if it was exposed to Europe for example. Needless to say,
such an environment was challenging for quants and non-quants alike, since both
camps tend to use stock specific information to differentiate between stocks.
The small cap opportunity set
We think of the opportunity set as the total available alpha on the table. Our main
interest is to understand what is driving that opportunity, because this can allow us to
position our strategies to pick in the orchard with the juiciest fruit. In Figure 24 we
show the opportunity set for the large cap universe, and in Figure 25 we show the
opportunity set for the small cap universe.

Both charts actually tell a similar story. The key result is the size of the blue portion
relative to the other colors. The blue represents the opportunity explained by stock
selection, whereas we can think of the other colors as representing the opportunity
from top-down calls like picking industries and styles. When the financial crisis
exploded in 2008, we moved into a much more macro-dominated world. As a result,

the portion of overall opportunity that could be explained by individual company
characteristics (e.g., valuation, growth profile, earnings quality, etc.) shrunk sharply; no
one cared if a stock looked good on fundamentals if it was exposed to Europe for
example. Needless to say, such an environment was challenging for quants and non-
quants alike, since both camps tend to use stock specific information to differentiate
between stocks.
However, the good news is that both charts show that bottom-up stock picking is
making a strong comeback. The blue area in both charts has reached levels last seen in
2007. The crucial observation is that the relative opportunity coming from stock
selection is higher for small cap stocks. In other words, this universe is particularly
fruitful for managers with skill in picking individual stocks. Note that the relative
opportunity set has remained relatively steady during the past month for small caps.
Valuation spreads
Similar to the opportunity set, valuation spreads allow investors to gauge the level of
stock selection opportunity in the market. Widening valuation spreads typically indicate
more stock-level differentiation and therefore a better environment for stock selection.
On the other hand, narrowing valuation spreads are indicative of lower levels of stock
differentiation. Figure 26 and Figure 27 show the median, 25th percentile, and 75th
percentile of trailing price to earnings for the Russell 1000 and 2000 index constituents.
Interestingly, we see that valuation spreads are wider on a more consistent basis for
small cap stocks. This reinforces the earlier evidence we saw in the opportunity set; the
small cap space is rich with opportunity for skilled stock pickers.

Keeping an eye on correlations
Closely related to the opportunity set and valuation spreads is the median pairwise
correlation among stocks in the market. This is calculated by taking every possible pair
of stocks, and computing the correlation of their monthly returns based on the past 24
months of data, and then taking the median across all the pairs. Figure 28 shows the
median pairwise correlation for large caps. While it has come down from the peak in
the financial crisis, it is still relatively high compared to its long-term average, so
investors are not yet completely out of the woods. Interestingly, in general median
pairwise correlations for small cap stocks (Figure 29) tend to be lower when compared
to large cap stocks. This tells us that small cap names tend to trade more on their own
merits, rather than being driven by common factors.

Top-down country rotation
CCRM country rotation model
Our Composite Country Rotation Model (CCRM) uses three sets of inputs to
dynamically rotate between countries in the MSCI All Country World Index.
The inputs include top-down macro signals (e.g. VRP, Kelly’s Tail Risk),
aggregate bottom-up fundamental signals (e.g. country-level valuation and
momentum), and lead-lag signals based on economic trade linkages.
For complete details on the model, please see Luo et al., “Signal Processing:
New Insights in Country Rotation”, 9 February 2012.
Current recommendations
Figure 51 and Figure 52 show the top and bottom third of countries, as ranked currently
by our CCRM model. The bars show what is driving these calls.

Top-down asset allocation
Quant Tactical Asset Allocation (QTAA) model
Our Quantitative Tactical Asset Allocation (QTAA) model uses a model-of-
models methodology to rotate between six asset classes.
The model uses a wide range of fundamental and market-based factors as
inputs, and dynamically selects a subset of those factors to use at each point in
time.
For complete details on the model, please see Luo et al., “Signal Processing:
Quant Tactical Asset Allocation”, 19 September 2011.
Current recommendations and performance
Figure 55 shows the current ranking of our six asset classes, ranked from best to worse
in terms of month-ahead forecast returns. Figure 56 shows the monthly performance of
the QTAA model over time.

Hypothetical Disclaimer
Backtested, hypothetical or simulated performance results have inherent limitations. Unlike an actual performance
record based on trading actual client portfolios, simulated results are achieved by means of the retroactive application of
a backtested model itself designed with the benefit of hindsight. Taking into account historical events the backtesting of
performance also differs from actual account performance because an actual investment strategy may be adjusted any
time, for any reason, including a response to material, economic or market factors. The backtested performance
includes hypothetical results that do not reflect the reinvestment of dividends and other earnings or the deduction of
advisory fees, brokerage or other commissions, and any other expenses that a client would have paid or actually paid.
No representation is made that any trading strategy or account will or is likely to achieve profits or losses similar to
those shown. Alternative modeling techniques or assumptions might produce significantly different results and prove to
be more appropriate. Past hypothetical backtest results are neither an indicator nor guarantee of future returns. Actual
results will vary, perhaps materially, from the analysis.
