In Summary
Numerous retail investors lost fortunes
participating in an endeavour that they barely understood. The boom is
evident in the fact that 10 IPO’s conducted since 2000 occurred during
this period.
Indeed, the ensuing crash led to the disappearance
of the retail investor from the Nairobi Securities Exchange, with most
activity nowadays being dominated by foreign and local corporate
investors.
The decline in retail activity has been brought
about by a number of issues. Specifically, the fall of a number of
stock-brokers, the increasing appeal of the real estate sector and some
issues of corporate governance amongst some listed companies. However,
there is an element of psychology that has affected retail investor
participation at the bourse.
A recent working paper at the Cleveland Fed entitled “Friends Do Let Friends Buy Stocks Actively”,
shows that increased social activity leads to more active investment by
investors. In essence, the more sociable you are, the more likely you
are to trade your portfolio more actively.
Further research has shown that higher returns
lead investors to be more sociable and engage in more conversation with
other investors.
A study in 2009 showed that in Taiwan, retail
investors underperform the market by an average of 3.8 per cent and
accumulate losses that sum to 2.2 per cent of Taiwan’s GDP. This is a
startling statistic that shows the adverse effects of active portfolio
management on wealth creation. If the same statistics applied in Kenya,
then it would mean that active investors lose about Sh9 billion per
annum.
Numerous studies have shown a link between investor activity and wealth erosion.
Socialising is important in a number of domains,
career advancement, marital stability, academic success and even
business success to name a few are some of these domains. However, it
seems that investing is not one of them. Through socialisation, one is
likely to get caught up in investment fads or feel the urge to “keep up
with the Joneses”.
Even professional fund managers are liable to this
“socialisation bias”. As Warren Buffett aptly puts it “time is a friend
to the fundamentalist and a foe to the faddist”; in this case, the
faddist being the overly active investor.
A casual reading of the above would seem to
suggest that I am advocating for retail investors to passively invest in
the stock market through mutual funds and other such professionally
managed investment vehicles. Actually, this is not the thrust of the
argument. The key take-out is that an understanding of the psychological
biases that inform investment decisions is critical to make good
decisions.
For investors, a good handle or awareness of the
psychological biases that influence your life, not only investment is
required. Emotional intelligence therefore is crucial for investment
success.
Retail investors should take note that over the
really long run, when dividends and capital gains are accounted for,
stock markets tend to do better than real estate.
Retail investors should therefore troop back to
the stock market carefully with the knowledge that a “socialisation
bias” exists and it is likely to erode your wealth. In short, do not
invest on the basis of stock tips received whilst sharing a beer with
your friends
