Success Variation by Security Type
Differences in Success Rate can be examined in securities
with different characteristics.
Positions are group into buckets of interest to the manager
and Success Rates are calculated for each bucker. For
example a manager might be interested in seeing how his
Success Rate differs when he takes positions in Small, Mid,

Whenever significant differences are identified we look at

different market conditions. When persistent differences are
found we can begin the process of drilling down further to
understand the source and implication of the differences and
the potential performance improvement of acting on the
differences and doing more of what is consistently more
successful and less and that which succeeds less often.
Success differences can be examined across any
measurable security characteristic. Often these
Relative P / E characteristics are measurable with publicly observable data
such as company size, share price volatility or Price to
We can also work with characteristics assigned by managers
themselves, for example “Management Quality”.
Success Variation by Behaviour
We also look at how Success varies with differences in the
behaviour of managers.
Behaviours of common interest include the holding period of
positions – either realized or expected at the outset of the
position, overweight / long positions compared with
underweight / short positions and Focus (how often a
Shortest Longest manager has taken positions in specific securities in the

Other behaviour types might include time of day, size of
position at opening, stated conviction at opening and time
taken to reach maximum position size.
Of course behaviour types can be mixed with security type
based analysis, looking at, for example the difference in
Success for long and short decisions in Small, Mid, Large
Underweights Overweights and Mega cap stocks.

We also include physiological measurements of stress as a
Focus manager behaviour type and can examine Success
difference as a function of stress load.
All of these partioning methods are also used for other
metrics in the Trading Equation, such as the Payoff Ratio.
Behaviour Change Case Study
Holding Period The manager was exhibiting a strong tendency to cut
winners earlier than losers and was not getting to full
position size in the Successful positions.
This was depressing his Payoff Ratio and total return.
Analysis of Winning and Losing position return traces
aligned around the Position Closing date revealed that the
Shortest Longest manager was being shaken out of winning positions by
statistically insignificant retracements. He was actually “too
good” at cutting on small loses in his winning positions.

A proprietary set of measurements reveals how well timed entries and
exits are relative to the best available entry and exit points. Our cross
sectional efficiency measure examines the degree of skill present in the
selection of specific securities from the available universe subject to
user defined constraints. Skill can be compared between managers for
selection and allocation purposes and within different security groups
and behaviour types to help individual managers improve performance.
Another set of proprietary metrics measure precisely where, within the
distribution of individual returns, total return is coming from. This gives
allocators a unique measure of style and individual managers the ability
to identify the characteristics of the positions that matter most to total
