We are all guilty of it, but it is probably the single most dangerous
investment sin. Perhaps it is part of our social evolution to conform. A
sort of “Eat shit 17 quadrillion flies can’t be wrong”. With regards to
financial markets you may have seen the same shit, but given a pseudo-
intellectual spin such as “perfect market theory” or its ilk which
implicitly suggest that markets are right and you are wrong, albeit an
imperfect market theory would be just as valid. Human capacity for
self-delusion based on information and normative conformity bias is well
documented and includes Asch’s classic Conformity experiment which is
well worth watching, if only for the appalling 1970’s hairstyles.

Ok,
so over the past five years we have been taught that bad news is good
news as market liquidity is dominated by central bank policy and that
all dips should be bought (see http://www.youtube.com/watch?v=0akBdQa55b4)
and that yield is good, almost regardless of risk. If it’s gone up in
price, find a justification, however spurious and then flex the
assumptions to add at least 10% to the price to keep compliance happy
with the endless buy recommendation. This self-reinforcing consensus
however is little more than a mass goal-seek. Sell side careers do
better during the longer periods of cyclical upswing and if it all goes
pear-shaped, then the flawed recommendation can be buried along with the
general debris. For buyside, the pressure on short term returns is also
intense and bucking the trend can also be expensive to careers, ergo
momentum investing rules and in turn merely reinforces the conformity
bias until the big reset. A particularly interesting feature of the Asch
experiment was also the effect of introducing an additional potential
dissenting voice to the group and the speed at which it could puncture
the group delusion. Quite what will represent that ‘additional voice’ in
today’s markets will have to be seen, but take care because when it
happens, as it always does, it will be quick.
I was
reminded of the pervading power of recency bias in a meeting with an
investment manager who was interested that my growthrater system did not
share his upbeat view of the value of a stock; in this case Nestle, a
solid consumer group with a good record of historic growth but with
current revenue growth falling short of the expectations that rising
Asian demand were expected to deliver. Notwithstanding, the investor was
probably referring a post interest cost of capital (WACC) rather than a
more robust pre-interest one, his position was that the market (aka big
sell-side) were pushing the stock on the basis of a seriously
sub-market cost of capital. If growth is slowing and volatility
increasing however, this looked more like a goal seek to justify where
the stock, or they would like it be, rather than a serious revaluation
argument. In the ‘growth-rater’, the equity risk premiums used are those
for the market average, with the flex in target operating free cash
flow yield determined by variances in discount growth rating. Unlike the
above flexing of specific risk premium, this is not a function of a
subjective discount plucked out of the air to goal-seek a share price,
but directly related to what the company is actually achieving and is
expected to deliver in terms of organic revenue growth. As a consequence
it is considerably more immune from the group goal-seek. It may provide
uncomfortable results, but this should be expected from any rigorous
structured approach. My response to the cost of capital issue on Nestle
is simple and demonstrated with two charts. First, the chart of the
group’s organic revenue growth vs the growth rating being priced in by
markets against the backdrop of the share price. From 2004 to end 2011,
Nestle’s organic revenue growth was consistently above the growth rate
that was being priced into the shares. In other words you could buy
growth at a discount, ie Cheap. After that point, the relationship
inverted and markets were pricing growth at a premium to that being
delivered, a feature that has become more pronounced as organic revenue
growth rates erode, ie Expensive. As the Growt-rater automatically
provides target price ranges (second chart) one can see that the time to
buy Nestle was before the shares outperformed and the to sell it before
it went down. Now how about that for a revolutionary investment
strategy!
