The most significant measure of a portfolio manager’s skills is commonly ignored.
I often hear fund managers say, “I only need to get it right a little over 50% of the time.” What they’re referring to is the . It’s just like baseball: it represents the proportion of their decisions that make them money, in absolute or relative terms. And yes, the best is to realize a decision-making hit rate of greater than 50% – whether you might be a fund manager or a standard person in on a regular basis life, right?
However, the actual fact is that the majority fund managers’ overall decision-making accuracy rate is lower than 50%. Our recent study found that only 18% of portfolio managers make more value-adding decisions than value-destroying decisions. We examined trading behavior in 76 portfolios over a three-year period and isolated the outcomes of investment decisions in seven key areas: stock selection, entry timing, sizing, scaling, sizing, scaling, and exit timing.
One of our findings: Although the hit rate attracts a whole lot of attention, it is commonly less consequential than the payout. RTP can greater than compensate for successful rate below 50%, and a poor RTP can completely negate the effect of a high hit rate.
Here’s why: Payoff measures whether a manager’s good decisions typically gained greater than his bad decisions lost. It is expressed as a percentage: over 100% is sweet; below 100% is bad. Just a few decisions that pay well above 100% can greater than compensate for several decisions that pay lower than 100%.
He didn’t use the term, however the legendary Peter Lynch emphasized payoff as a central theme: he told this to Louis Rukeyser in 1990 “You only need one or two good stocks per decade.” Of course, these would need to be VERY good stocks, but the purpose is that return is some of the essential aspects in successful skilled investing. Successful managers must make sure that their winners gain more overall than their losers lose.
It is probably ironic that asset owners and managers examine quite a lot of managerial statistics to differentiate luck from skill, but are likely to overlook the payoff. In fact, payoff is certainly one of the purest skill metrics there’s. Managers who consistently deliver over 100% payout show true investment expertise: They know when to carry and when to exit.
Essential behavioral alpha limit
The ability to exclude losers – and indeed Eliminate winners before they grow to be losers – the very best investors are good at this. And that manifests itself in a high payout.
The above diagram is from . It looks in any respect the trading decisions made by our sample of 76 energetic stock portfolios over the past three years and plots their hit rate versus their payoff. The dashed line represents what could be achieved by probability: if the manager half the time is correct with successful rate of fifty% and its average winner earns exactly as much as its average loser loses, which corresponds to a payout of 100%.
While managers’ hit rates fall inside a reasonably narrow band along the x-axis, their payoffs vary dramatically along the y-axis. The five top managers coloured magenta have each high hit rates and high payouts.
This chart and its use of payout as a key comparison metric for portfolio managers represents a crucial next step in the event of manager valuation methodology. It allows us to look beyond traditional valuation measures based on past performance – that are highly depending on random effects of luck and due to this fact are limited of their usefulness – and as a substitute concentrate on the standard of a manager’s decision making. And that may be a much more accurate assessment of their abilities.
