Contrarianism
August 2003
Omid Malekan:
Recently I have been thinking a lot about the contrarian approach, and have
come up with three obstacles that need to be overcome. For my purposes, I
define being a contrarian as going against a trend which has already sucked
in a large percentage of those who would play that trend, leading to a turn
in prices.
The first obstacle is determining what percentage of the players have
already taken a certain position. There are many indirect indicators to look
at, but no measure that I have seen is perfect. Volatility makes major
regime shifts over the years, options analysis could be skewed by hedging
strategies, and anecdotal evidence is just that, anecdotal. Surveys tell us
what people say, which could be very different from what they actually do.
Besides, if a perfect measure of "who is long and who is short" did exist,
widespread knowledge of it would eliminate its usefulness.
The second hurdle is picking a level to mark as an extreme. A cab driver
recommending GE may be a sign, but wouldn't 2 cab drivers be a bigger sign?
With the quantified sentiment measures statistical analysis makes the most
sense, but by definition major inflection points are rare, making purely
quantitative analysis shaky. My own experience has been that betting against
a VIX of 50 when it ends up topping out at 70 could be devastating when real
world constraints are taken into account, even if soon enough the index is
at 30.
But it's the final hurdle that bothers me the most. Markets are an extremely
open system in the long term, and a major move in one direction could be
self replicating in the short term. One cab driver recommending a stock that
has had a big run may be a sign, but what about the thousands of other cab
drivers who at the moment have no opinion of the stock. Couldn't another 10%
increase in the stock suck them in to buy, leading to a greater number of
cab drivers who are bullish on it? And couldn't the news of the profits of
the cab drivers eventually lead reluctant valuation based traders who are
lagging the stock in YTD returns to go long, all the while creating further
upside that makes shaky contrarians like myself throw in the towel?
I am certain that this territory has been covered before, and I have a
feeling that a system which is self-defeating below a certain magnitude but
self-fulfilling above it exists in the physical sciences, though I cant
think of any at the top of my head. Advice on where to take my investigation
is well appreciated.
Kim Zussman:
Contrarian examples are easier to see in hindsight than contemporaneously.
For example, the big sell-off in March just before the Iraq war: Generalized
fear about the outcome, another Vietnam, etc sent stocks south and VIX up.
Looking back, this was an excellent buying opportunity ( I bought a bit
then, with much trepidation after experiencing the prior 3 year bear).
I agree that markets are open (relatively unbounded) over long periods,
which at some level must contribute to the risk participants are taking. In
1996, Greenspan's "Irrational Exuberance" speech was prescient but 4-years
early. Shiller's work suggests mean reversion of stockmarket when PE's are
too high, and has over 100 years of data to support. Yet the trend
continued with vigor in 1990's, making poor those who bet on mean reversion.
To the extent that markets are at least partially efficient, VIX and VXN
should not be reliable indicators (and should become less reliable over time
as investors seek to exploit).
Let's say finance academics show in a series of (statistically valid) papers
that buying the market at VIX (or VXN, etc) over X results in positive returns
over 1 year:
http://papers.ssrn.com/sol3/papers.cfm?abstract_id=371461
These papers circulate to all the hedgies and investment houses who pay PhDs to
capitalize on anomalies. The houses in turn trade heavily according to these
findings. Will VIX based buying remain profitable? If VIX is an indelible
indicator of risk, then buying at a certain level should proscribe high
probability of either loss or gain, without knowledge of which. If high VIX
were an immutable indicator of profitable long entry, smart would buy (earlier
and earlier) and the indicator would not indicate.
IMO contrarian buy or sell signal points should be very difficult to identify
contemporaneously, otherwise they would be exploited by (all you) smart money
and would not form global minima and maxima. If you were around in 1987, how
would you know to throw in at the vertiginous convulsion (and the largest drop
since the great depression)? And even if you had some indicators, what about
the guts? Bail out 3/00? Why not?
James Lackey:
I have never lost more money than going against what I thought everyone already
knew. I have never missed so many opportunities, thinking that everyone knew,
so I was too late. I have never lost more opportunity by taking small profits
in what I thought was to sell the news as now everyone knows.
All that is retrospective, qualitative. But a close second is trading to get
even...and when I did I sold only to see the price rise 10-fold again...LACK
Mark Serafini:
Contrarianism is best performed in a context where the market is in the
process of creating a self-fulfilling/self-defeating paradox. Once you locate
those environments, you can then wait for the market to behave in a counterintuitive
manner...at that point in time you have found yourself a true contrarian
opportunity.
Omid Malekan:
Assuming the spec-list represents a fair cut of the investment world, much
can be learned from the recent discussion of contrarianism. Many of us admit
to the approach, and more importantly we all take a certain pleasure in it.
In my brief years of interaction with traders I have met many people who are
and love to talk about being a contrarian but I haven't met many who talk
with the same glee about just following the trend. I know there are many
trend-followers, but not many of them seem to get the added pleasure that
contrarians do just from their approach. I believe this comes from the fact
that if you are a good contrarian not only are you making money, but by
definition you are making money when the majority or "the crowd" is wrong
and thus losing money.
Now we have hit a trap. The first lesson most traders learn is how dangerous
trading for any other reason other than to make money is. And as much as
most traders will agree with me on this, most of us end up doing a trade for
external reasons (having a bad day, wanting to recoup losses, meeting a
certain profit goal, paying the rent) sooner rather than later. I submit
that being a contrarian should be added to the list. Why is it that most of
us usually complain about being early vs getting in too late? Does it have
something to do with wanting to pick the exact top, the points where the
greatest number of people are wrong?
I still see much value in the approach, but now believe that many of us are
contrarians because we get certain satisfactions, not necessarily because we
are good at it and make money.
Daniel V. Grossman
Omid, I recognize a similar tendency in myself, but would analyze it an an unfortunate "perfectionism".
Thus if I make two trades on a day:
1. I sell 1000 shares at the high (or within a cent or two of the high) for
the day, after which the stock drops significantly.
2. I sell 2000 shares not near the high for the day but making twice the
profit.
I would probably have stronger thoughts about, get more pleasure out of, the
first of these trades, because would demonstrate to myself how smart I was,
how my thinking and instincts were so perfect that I was able to get out at
the high.
Is this familiar to anyone, or is it solely my own counterproductive idiosyncrasy?
