Persistence of
Mutual Fund
Performance in
India
Summer Project 2012
Motivation of the study-1
• MFs offer diversification, expertise and pooling
• MFs offer small investors access to investment with a small
amount of capital
• At any point of time, there exists a large no. of scheme to
choose from
• Question is: How to choose the scheme (s), specially by
un-initiated investors
• It’s a common practice in India to choose the MF scheme
that has exhibited the best past performance
• Over the past 1/2/3 years
• A second factor is about ability of fund managers
Motivation of the study-2
• A fund manager may be able to generate abnormal return
from her portfolio during a particular period
• This may be due to certain coincidences
• E.g., chance selection of a promising stock or sector
• However, is the fund manager capable of repeating the
performance
• In other words, does past performance is any indicator of
future performance?
• Empirical evidence from the US and other markets show
that fund managers cannot beat the market
• Persistently over long-run
• Wherein a passive investment is more efficient
Indian MF Industry
• Evolution
• 1963 - Unit Trust of India
• 1987 – LIC and General Insurance Corporation, PSBs are
allowed to launch
• 1993 – Foreign and private players were allowed
• AMFI reported Rs.47,004 crores AUM.
• In 2012, there are 42 AMCs with AUM of Rs.692,705
crores
• A slight decline after entry-load ban was imposed w.e.f.
1st August 2009 (from around Rs.8 lakh crores).
Objective
• Analyze performance of the equity diversified mutual funds
deploying standard measures risk-adjusted performance.
• Past 36-months data were used to compute performance
measure
• Regressed on following 12-, 24- and 36-month performances
• Starting from April 1997 (first complete 36-month past
performance window)
• Rolling the process forward by a month until April 2009
• Thus a maximum of sets of 180 observations for a scheme
• Match with future average return and the return by the buy and
hold strategy of the investor over the next 1year, 2years &
3years
Data
April 1994 – March 2012
Net Asset Value
• The period covers the different bull and bear phases of
the Indian equity market.
• The monthly closing NAV of 242 equity diversified
mutual funds collected from the websites of AMFI
(Association of Mutual Funds in India) and from the
smctradeonline.com.
• For the final analysis only 169 mutual fund schemes have
been taken into account for which the data was available
for at least 72 months (past 36 & future 36 months) i.e.,
• funds launched up to March 2008.
Benchmark and T-Bill
• The monthly closing price data of each index is collected
from the websites of BSE (Bombay Stock Exchange) and
NSE (National Stock Exchange).
• The monthly T-Bill returns (proxy for risk-free rate) data
were collected from the Handbook of Statistics on Indian
Economy, various issues, published by RBI.

Methodology
Formulae and Techniques
NAV Return
• The monthly return of each fund has been calculated from the
monthly closing NAV by using the following formula:
Rt+1 = NAVt+1 - NAVt
NAVt
where Rt+1 = Return of the mutual over month ‘t+1’.
NAVt = Closing NAV of the month ‘t’.
NAVt+1 = Closing NAV of the month ‘t+1’.
Benchmark Return
• The monthly return of all the 15 indices has been
calculated using the following formula where RB stands
for the return of the benchmark :
RB.t+1 = Pt+1 - Pt
Pt
where RB.t+1 = Return of the benchmark over the month ‘t’
Pt = Closing price of the month ‘t’
Pt+1 = Closing price of the month ‘t+1’
Sharpe Ratio
• The most commonly used measure of risk adjusted
performance is the Sharpe ratio which measures the
fund’s excess return per unit of its risk
• Given that
Rp = Return of the portfolio (Mutual Fund)
Rf = Risk free rate of return (T-Bill)
ϬP = Standard dev. of the portfolio return
P
fP RR
RatiosSharpe


_'
Security Market Line
• Security Market Line (from CAPM) represents the expected total
return of every security or portfolio i as a linear function of the return
of the market portfolio m :
Ei = Rf + βi [Em - Rf ]
where Ei ≡ E[Ri] denotes the unconditional continuous
expected return of the portfolio I
βi = cov(Ri , Rm) is the beta of the portfolio i.
ϭ2(Rm)
• This equilibrium relation corresponds to the market model
rit = αi + βirm + ϵit ,
where ri = Ri – Rf denotes excess return on the portfolio i.
Jensen’s Alpha
• Total risk is captured by ϭ
• Consists of systematic risk (explained by market index)
• And capture by beta (β)
• And non-systematic risk (not explained by the CAPM
regression)
• The intercept term for a stock should be zero theoretically
• And is indeed so for most individual stocks empirically
• Jensen proposed that the intercept for an actively-
managed portfolio should be a performance of the
manager
• A measure of how much additional return a manager can
generate over the benchmark
• Without exceeding the systematic risk of the benchmark
Treynor Ratio & Information Ratio
• We don’t directly use Jensen’s alpha here (thoough we
computed) for reasons explained later
• The Treynor Ratio (TR) is the ratio of Jensen’s alpha
over the portfolio beta
• Another measure deployed here is the Information ratio,
which is Jensen’s alpha per unit of non-systematic risk
of the portfolio (measured by the standard deviation of
the market model residuals)

Coefficient of Variation
• Since none of the above measures takes into account the
benchmark, we deploy another measure
• Excess of the return per unit of total risk of the portfolio
over that of th benchmark:
CR = Rp/Ϭp - Rb/Ϭb
where Rp = Return of the portfolio (Mutual Fund)
Rb = Return of the benchmark
Ϭp = Standard deviation of return of portfolio
Ϭb = Standard deviation of return of benchmark

Literature Review
International Fund Market
• Grinblatt and Titman (1992), Carhart (1994), Sharpe(1995) among
others, provided evidence that confirmed the predictability of future
performance by past performance – returns persists
• Elton, Gruber and Blake (1996) reported that the past carries the
information about the future performance of the funds and they
highlighted that both the 1 year and 3 year alphas convey the
future information.
• Michael Stutzer, on the contrary, observed that the fund
managers who can beat the benchmark for the long run
surprisingly still have significant probability of underperforming
• which extends over a long period of time.
Indian Evidence
• A sample of 50 Indian mutual fund was analyzed over 26
months by Roy and Bhattacharjee found that though in
short term the mutual funds were able to generate
above normal return.
• Deb, Banerjee and Chakrabarti observed that on an
average fund managers have not been able to beat
their style benchmark.
• Analysis of open ended equity mutual fund schemes
indicate that the performance of majority of sample
was not significantly related to their market
movements during the study period.
• Managerial Ability
• Dey, Yi Wang and Yexiao Xu (2001) highlighted that the
fund managers may possess superior stock selection skills
• Deb, Banerjee and Chakrabarti (2007) found very little
evidence of market timing skill of fund managers though
their stock selection ability was decent enough to produce
good returns from the market.
• Bear Market
• Dr. S Narayan Rao observed that the fund managers were
able to diversify the risk and even managed to give returns
greater than risk free return.
• But the debt funds were ultimate winners

• Sharpe Ratio
• The future performance of all kind of –vely correlated.
• Information Ratio
• The predicament is almost similar across all types of
AMC’s
• Treynor’s Ratio
• Insignificant
• Coefficient of Variation
• Private Indian & Foreign AMC imitated by its past.
• While it is trivial for Indian Joint Ventures.
• Unclear for Public AMC.
Further Research
Leaping Data Limitations
• The analysis can be extended for each AMC’s seperately.
• The analysis can be done by grouping the schemes on the basis
of capital.
• The past performance measure can be calculated over 1 year, 2
years & 3 years period for that purpose weekly data is to be
made available.
• The analysis can be done for a particular market scenario say
during sub prime crisis or other phases of boom and bust.

Risk Adjusted Return
• In 1996 Elton, Gruber and Blake made a significant
contribution to the field by addressing the issue of survivorship
bias of the testing sample of funds.
• They refined the technique to calculate the risk adjusted return
using the historical return data.
• Concluded that the past carries the information about the
future performance of the fund and they highlighted that
both the 1 year and 3 year alphas convey the future
information.
M3 measure
• Muralidhar (2000) proposed a new measure called M3
for the construction of optimal portfolio of fund,
benchmark and risk free assets.
• This new measure accounts for the difference in the
standard deviation of the benchmark and portfolio and the
correlations of mutual fund portfolios and their
benchmark for an investor’s relative risk target.
Rating Firms
• Michael Stutzer analyzed the ratings given by different
rating firms who partition the funds into different
categories based on their style, size, asset class & sectors.
• He also reported that the fund managers who can beat
the benchmark for the long run surprisingly still have
significant probability of underperforming which
extends over a long period of time.
Benchmark
• Stutzer also identified that the Sharpe Ratio which is part
of the basis for rating produced by S&P and Charles
Schwab is not appropriate for rating purpose because it
uses a T-Bill benchmark instead of benchmark that user
wants to beat.
• So in our study we also took the corresponding
benchmark for each fund that the fund managers want
to beat and calculated the excess return over the market
In Indian Context
PCM
• A sample of 50 Indian mutual fund was analyzed over 26
months by Roy and Bhattacharjee.
• Calculating the Performance Change Measure (PCM)
developed by Grinblatt and Titman (1993) at the lag of one
month, one quarter and one year and
• Found that though in short term the mutual funds were able
to generate above normal return but on average the
combined PCM of all mutual funds is significantly different
from zero.
Return Based Style
Analysis
• Deb, Banerjee and Chakrabarti did a return based
style analysis of Indian mutual fund
• Analyzed their relative performance with respect to the
style benchmark obtained by doing quadratic
optimization of asset class factor model using historical
monthly return
• Found out that on an average fund managers have not
been able to beat their style benchmark.
Open Ended Equity
Mutual Fund
• The result of analysis of risk & return relationship of
open ended equity mutual fund schemes of both the
public and private sector mutual funds in India indicate
that the performance of majority of sample was not
significantly related to their market movements
during the study period.
Managerial Ability
• The investigation of underperformance of mutual fund
portfolios by Dey, Yi Wang and Yexiao Xu (2001) highlighted
that the fund managers may possess superior stock selection
skills
• But the substantial gains could be achieved by improving the
efficiency of allocation of mutual fund assets.
• They also suggested the when the mutual fund turnover is
excessive then fund manager may rely on the stock price
momentum for profitable returns.
Market Timing & Stock
Selection
• A similar study based on the market timing and stock
selection ability was done by Deb, Banerjee and
Chakrabarti (2007)
• Using conditional and unconditional model over Indian
fund market
• Found very little evidence of market timing skill of fund
managers though their stock selection ability was decent
enough to produce good returns from the market.
Bear Market
• Dr. S Narayan Rao evaluated the performance of Indian mutual
funds in bear market through return performance index, risk-return
analysis, Treynor’s ratio, Sharpe ratio, Sharpe measure, Jensen
measure and Fama measure.
• He witnessed that the Medium term debt funds performed extremely
well during that period while InfoTech equity funds suffered the
most.
• Some fund managers were able to diversify the risk and maximize
the return and even few managed to give returns greater that risk free
return during bear market but the debt fund were the ultimate
winners.
Sub Prime Crisis
• Bose (2012) tried to throw the light on the mutual funds’
performance during the recent financial crisis which
tested the resilience of Indian mutual fund industry.
• Huge outflow of investment from the equity fund markets
a huge surge of investment in the debt and gilt fund
markets driven by the low policy rates and the risk averse
attitude of the investors during that period.

Persistence of Mutual Fund Performance in India

    Motivation of thestudy-1 • MFs offer diversification, expertise and pooling • MFs offer small investors access to investment with a small amount of capital • At any point of time, there exists a large no. of scheme to choose from • Question is: How to choose the scheme (s), specially by un-initiated investors • It’s a common practice in India to choose the MF scheme that has exhibited the best past performance • Over the past 1/2/3 years • A second factor is about ability of fund managers
  • 3.
    Motivation of thestudy-2 • A fund manager may be able to generate abnormal return from her portfolio during a particular period • This may be due to certain coincidences • E.g., chance selection of a promising stock or sector • However, is the fund manager capable of repeating the performance • In other words, does past performance is any indicator of future performance? • Empirical evidence from the US and other markets show that fund managers cannot beat the market • Persistently over long-run • Wherein a passive investment is more efficient
  • 4.
    Indian MF Industry •Evolution • 1963 - Unit Trust of India • 1987 – LIC and General Insurance Corporation, PSBs are allowed to launch • 1993 – Foreign and private players were allowed • AMFI reported Rs.47,004 crores AUM. • In 2012, there are 42 AMCs with AUM of Rs.692,705 crores • A slight decline after entry-load ban was imposed w.e.f. 1st August 2009 (from around Rs.8 lakh crores).

    Objective • Analyze performanceof the equity diversified mutual funds deploying standard measures risk-adjusted performance. • Past 36-months data were used to compute performance measure • Regressed on following 12-, 24- and 36-month performances • Starting from April 1997 (first complete 36-month past performance window) • Rolling the process forward by a month until April 2009 • Thus a maximum of sets of 180 observations for a scheme • Match with future average return and the return by the buy and hold strategy of the investor over the next 1year, 2years & 3years
  • 6.

    Net Asset Value •The period covers the different bull and bear phases of the Indian equity market. • The monthly closing NAV of 242 equity diversified mutual funds collected from the websites of AMFI (Association of Mutual Funds in India) and from the smctradeonline.com. • For the final analysis only 169 mutual fund schemes have been taken into account for which the data was available for at least 72 months (past 36 & future 36 months) i.e., • funds launched up to March 2008.
  • 8.
    Benchmark and T-Bill •The monthly closing price data of each index is collected from the websites of BSE (Bombay Stock Exchange) and NSE (National Stock Exchange). • The monthly T-Bill returns (proxy for risk-free rate) data were collected from the Handbook of Statistics on Indian Economy, various issues, published by RBI.

    NAV Return • Themonthly return of each fund has been calculated from the monthly closing NAV by using the following formula: Rt+1 = NAVt+1 - NAVt NAVt where Rt+1 = Return of the mutual over month ‘t+1’. NAVt = Closing NAV of the month ‘t’. NAVt+1 = Closing NAV of the month ‘t+1’.
  • 12.
    Benchmark Return • Themonthly return of all the 15 indices has been calculated using the following formula where RB stands for the return of the benchmark : RB.t+1 = Pt+1 - Pt Pt where RB.t+1 = Return of the benchmark over the month ‘t’ Pt = Closing price of the month ‘t’ Pt+1 = Closing price of the month ‘t+1’
  • 13.
    Sharpe Ratio • Themost commonly used measure of risk adjusted performance is the Sharpe ratio which measures the fund’s excess return per unit of its risk • Given that Rp = Return of the portfolio (Mutual Fund) Rf = Risk free rate of return (T-Bill) ϬP = Standard dev. of the portfolio return P fP RR RatiosSharpe   _'
  • 14.
    Security Market Line •Security Market Line (from CAPM) represents the expected total return of every security or portfolio i as a linear function of the return of the market portfolio m : Ei = Rf + βi [Em - Rf ] where Ei ≡ E[Ri] denotes the unconditional continuous expected return of the portfolio I βi = cov(Ri , Rm) is the beta of the portfolio i. ϭ2(Rm) • This equilibrium relation corresponds to the market model rit = αi + βirm + ϵit , where ri = Ri – Rf denotes excess return on the portfolio i.
  • 15.
    Jensen’s Alpha • Totalrisk is captured by ϭ • Consists of systematic risk (explained by market index) • And capture by beta (β) • And non-systematic risk (not explained by the CAPM regression) • The intercept term for a stock should be zero theoretically • And is indeed so for most individual stocks empirically • Jensen proposed that the intercept for an actively- managed portfolio should be a performance of the manager • A measure of how much additional return a manager can generate over the benchmark • Without exceeding the systematic risk of the benchmark
  • 16.
    Treynor Ratio &Information Ratio • We don’t directly use Jensen’s alpha here (thoough we computed) for reasons explained later • The Treynor Ratio (TR) is the ratio of Jensen’s alpha over the portfolio beta • Another measure deployed here is the Information ratio, which is Jensen’s alpha per unit of non-systematic risk of the portfolio (measured by the standard deviation of the market model residuals)   ˆ ˆ TR )(ˆ ˆ   IR
  • 17.
    Coefficient of Variation •Since none of the above measures takes into account the benchmark, we deploy another measure • Excess of the return per unit of total risk of the portfolio over that of th benchmark: CR = Rp/Ϭp - Rb/Ϭb where Rp = Return of the portfolio (Mutual Fund) Rb = Return of the benchmark Ϭp = Standard deviation of return of portfolio Ϭb = Standard deviation of return of benchmark

    • The analysiscan be extended for each AMC’s seperately. • The analysis can be done by grouping the schemes on the basis of capital. • The past performance measure can be calculated over 1 year, 2 years & 3 years period for that purpose weekly data is to be made available. • The analysis can be done for a particular market scenario say during sub prime crisis or other phases of boom and bust.

    Risk Adjusted Return •In 1996 Elton, Gruber and Blake made a significant contribution to the field by addressing the issue of survivorship bias of the testing sample of funds. • They refined the technique to calculate the risk adjusted return using the historical return data. • Concluded that the past carries the information about the future performance of the fund and they highlighted that both the 1 year and 3 year alphas convey the future information.

    M3 measure • Muralidhar(2000) proposed a new measure called M3 for the construction of optimal portfolio of fund, benchmark and risk free assets. • This new measure accounts for the difference in the standard deviation of the benchmark and portfolio and the correlations of mutual fund portfolios and their benchmark for an investor’s relative risk target.

    Rating Firms • MichaelStutzer analyzed the ratings given by different rating firms who partition the funds into different categories based on their style, size, asset class & sectors. • He also reported that the fund managers who can beat the benchmark for the long run surprisingly still have significant probability of underperforming which extends over a long period of time.

    Benchmark • Stutzer alsoidentified that the Sharpe Ratio which is part of the basis for rating produced by S&P and Charles Schwab is not appropriate for rating purpose because it uses a T-Bill benchmark instead of benchmark that user wants to beat. • So in our study we also took the corresponding benchmark for each fund that the fund managers want to beat and calculated the excess return over the market

    PCM • A sampleof 50 Indian mutual fund was analyzed over 26 months by Roy and Bhattacharjee. • Calculating the Performance Change Measure (PCM) developed by Grinblatt and Titman (1993) at the lag of one month, one quarter and one year and • Found that though in short term the mutual funds were able to generate above normal return but on average the combined PCM of all mutual funds is significantly different from zero.

    Return Based Style Analysis •Deb, Banerjee and Chakrabarti did a return based style analysis of Indian mutual fund • Analyzed their relative performance with respect to the style benchmark obtained by doing quadratic optimization of asset class factor model using historical monthly return • Found out that on an average fund managers have not been able to beat their style benchmark.

    Open Ended Equity MutualFund • The result of analysis of risk & return relationship of open ended equity mutual fund schemes of both the public and private sector mutual funds in India indicate that the performance of majority of sample was not significantly related to their market movements during the study period.

    Managerial Ability • Theinvestigation of underperformance of mutual fund portfolios by Dey, Yi Wang and Yexiao Xu (2001) highlighted that the fund managers may possess superior stock selection skills • But the substantial gains could be achieved by improving the efficiency of allocation of mutual fund assets. • They also suggested the when the mutual fund turnover is excessive then fund manager may rely on the stock price momentum for profitable returns.
  • 82.
    Market Timing &Stock Selection • A similar study based on the market timing and stock selection ability was done by Deb, Banerjee and Chakrabarti (2007) • Using conditional and unconditional model over Indian fund market • Found very little evidence of market timing skill of fund managers though their stock selection ability was decent enough to produce good returns from the market.

    Bear Market • Dr.S Narayan Rao evaluated the performance of Indian mutual funds in bear market through return performance index, risk-return analysis, Treynor’s ratio, Sharpe ratio, Sharpe measure, Jensen measure and Fama measure. • He witnessed that the Medium term debt funds performed extremely well during that period while InfoTech equity funds suffered the most. • Some fund managers were able to diversify the risk and maximize the return and even few managed to give returns greater that risk free return during bear market but the debt fund were the ultimate winners.
  • 84.
    Sub Prime Crisis •Bose (2012) tried to throw the light on the mutual funds’ performance during the recent financial crisis which tested the resilience of Indian mutual fund industry. • Huge outflow of investment from the equity fund markets a huge surge of investment in the debt and gilt fund markets driven by the low policy rates and the risk averse attitude of the investors during that period.
