till it gives us a migraine, but sometimes
things just don’t work out and nobody could
have foreseen it.
So what makes for a good risk manager?
Well, it is someone who carefully chooses
the best odds. He will sometimes win, and
sometimes lose. But, he will always make deliberate and careful
trade-offs between his assessment of risk and return: the most
expected return for the least risk. Sometimes good managers
accept a low return when it is safe (like buying government
bonds); sometimes they accept a lot more risk in return for a
higher expected return (like investing in the stock market).
Bad managers are those people who just don’t get it. They accept
worse average returns for higher risks. Clearly that’s dumb. But
it is also where it gets tricky. Because if they accept very high
risks, in spite of lower average returns, every once in a while one
of these morons will actually hit the jackpot . . .* That is, if we
take the top one percent of top performers, they’re likely to be
those people who didn’t get it at all . . . but just got incredibly
lucky!
The same is true – as Stanford’s Professor Jim March asserted –
for CEOs. The ones that are the eye-catching top performers are
likely the ones who just don’t get it. The dangerous thing is that
they are also the ones with the absolute highest return in their
business. Therefore we naïvely believe that they “do get it” and,
in fact, are quite brilliant. Moreover, that’s what they start to
believe as well (“I win again; I must be brilliant!”). Yes, they got
lucky once, they might get lucky twice, or three times (at which
point we start to notice them) but eventually their luck will turn
(Bernard Tapie, Jeff Skilling, Cees van der Hoeven, and Conrad
Black come to mind).
* In statistical terms, good managers have a normal distribution around
a relatively high average; bad managers have a lower average return but a
distribution with “fat tails”. Consequently, because of the long right-hand tail, the
top performers stem from the “bad managers” distribution/pool.
