The characteristics of experts
Are You an Expert?
Michael J. Mauboussin Legg Mason Capital Management outlines
in a recent whitepaper the “Characteristics of Experts”:
“Given that experts exist in diverse domains, psychologists
wondered whether they have much in common. The answer: a resounding yes.
Research on expert performance reveals seven robust and universal
characteristics:
1. Experts excel in their own domains, but not outside their domain. Expertise
is domain specific.
2. Experts perceive patterns in their domain.
3. Experts solve problems much faster than novices. Lightning chess, where
players only have a few seconds to decide a move, illustrates this point well.
4. Experts have superior short and long-term memory. When tested, experts appear
to have recall capacity that exceeds the limits of short-term memory.
5. Experts represent problems at a deeper level than novices…experts sort by
principle-based categories, while novices sort more literally, reflecting the
problem’s surface features.
6. Experts spend a lot of time solving problems qualitatively.
7. Experts have a strong sense of their own fallibility. Experts tend to be more
aware of their errors, why they fail, and when they need to check their answers.
I have been fond of Mauboussin’s logic for years. He nails it
head on most all of the time. How many people really ponder his views on
“expertise” in terms of their trading? I say not many. For example, I came
across a “risk capacity” survey online from a financial planning firm. Here is
one of the questions with the answer choices:
How would you rate your knowledge about investing in
general and more specifically, the relationship between risk, return, and time?
A. significantly below average
B. below average
C. average
D. above average
E. expert
The right answer is not the point here. If the great traders,
the experts, are living Mauboussin’s seven points, how does it help to pose the
question above? Isn’t the question above just an over-simplification to make
people feel good? Doesn’t it let them avoid the heavy lifting needed for real
trading excellence? The firm that poses the above question also makes these
assertions on their website:
1. It is virtually impossible to beat a market over time
through active investing.
2. Indexing is backed by Nobel laureates who have provided unbiased, rigorous,
empirical research, most notably the Modern Portfolio Theory.
3. Stock pickers are analogous to gamblers who rely on feelings and emotions
when making bets.
4. Time pickers or market timers move money in and out of different investments
in an attempt to profit from short-term cyclical events, which is a futile
endeavor.
5. Manager picking is not a reliable practice because the past performance of
money managers does not predict their future performance. Star money managers
fall from their stature sooner or later, since their stellar performance is
attributed to Lady Luck rather than skill.
Whoever wrote the above 5 points has not read
Market Wizards,
Fortune’s Formula or
Trend Following. Whoever wrote those 5 points doesn’t believe “expertise” is
possible. But it is possible. There are many trading experts or Market Wizards
who have been whipping the market for decades. Consider one of the great trend
followers, David Harding of
Winton Capital, who
was recently asked: ‘Because recent performance has been good, does that
necessarily mean that future performance will be bad?’ His answer:
“Au contraire. There is a danger of people over
extrapolating recent good performance into the future and being too optimistic
about what we’re going to achieve. But, equally, there is no evidence of mean
reversion, in the sense that whenever we have a good period that’s inevitably
followed by a bad period or that when we have a bad period that’s followed by a
good period. It’s a biased coin tossing exercise. It’s like tossing coins.
Luckily we strongly believe our coin will land profit side up, rather than loss
side up, 60 per cent of the time. But there is no forecasting the future of our
returns from our recent performance. However much your feelings tell you
something, your gut tells you something, the gut is very misleading in this
context.”
David has that “expertise” Mauboussin speaks to. In my
conversation with David he stressed that he can always tell a client how much
risk he is taking, but he can never tell you how much he will make. He is
clearly focused on his own fallibility? Are you focused on your own fallibility?
Holy Grail Reminder: News is Not Useful
Consider from this week:
“NEW YORK (Reuters) – U.S. stocks extended gains on
Tuesday, with both the Nasdaq Composite and the S&P 500 index rising above 1
percent, as minutes from a December U.S. Federal Reserve policymakers’ meeting
signaled the central bank’s 1-1/2 year campaign of rate increases was likely
near an end. The Dow Jones industrial average jumped 80.85 points, or 0.75
percent, at 10,798.35. The Standard & Poor’s 500 Index was up 14.11 points, or
1.13 percent, at 1,262.40. The technology-laced Nasdaq Composite Index advanced
29.06 points, or 1.32 percent, at 2,234.38.”
Is this the trigger to enter? Is that the point of this news
tidbit? Get in now? If you do get in now, when do you exit? If you do get in
now, which market? If you get in now, how much do you bet of your limited
bankroll?
