In financial markets, the decisions made by
investors largely depend on their expectations about the future. Expectations
are largely made based on the historical performances of themselves as well as
their investing targets. They compare the historical performances of their
models with the actual targets' historical performances in order to improve the
effectiveness of their models, then they use their amended models to make their
expectations. Every investor in financial markets is doing the same, the only
difference is the differences between their models. Some people argue that
people do not only look back to the history, they also try to foresee changes
in the future, for example, the coming central bank monetary policies and
governments' fiscal policies. However, do people really make forecasts without
looking back from the history? The answer is definitely no. Many peoples'
forecasts are made by their individual experience, and their experience is made
of the history they have experienced.
We have to admit that without considering
black swan events, when the future is further ahead, it is harder to predict,
this is because more changes will be made when the future is further ahead of
us. Usually in order to compensate higher risk, we expect higher returns, this
is why the rates for long term investment are generally higher than the rates
for short term. However, if we consider the discount rate, it means the value
in the future is lower than the value at the moment. If the discount rate is
much greater than the risk-free return rate, it is almost meaningless to expect
returns from a long term project, as for a company, the decisions are usually
made based on at most a 5 year period, even for the majority of governments,
this is true as well; therefore, the returns from a project which lasts over 5
years are more dependent of the exogenous factors rather than the endogenous
factors. There are much more uncertainties about exogenous factors than uncertainties
around endogenous factors, as countless factors are able to influence the
environment and different participants can have different degrees of influence
on the environment, which makes it impossible to estimate an appropriate outcome
of the environment (the market or the economy) in a long time.
Therefore, I
think being “short-sighted” is probably a good choice when participating in the
financial market, as almost all of our possible expectations and decisions are
made on our historical experience and observations, when the future is further
ahead, our expectations and decisions become more likely to be wrong. Give an
example, the housing crisis in US in 2007 was a result of Clinton’s housing
plan which aimed to provide housing for more people in America. Even if you
could see a crisis would come in 2007, you could not short the housing market immediately,
the most profitable way would be shorting in early 2007, and such profiting
method is not about making good expectations about some events in the future,
it is about having critical observation of the market and making the right move
ahead of others.
