Many stock pundits and advisors strongly recommend
diversification, that is, holding more than one stock to reduce risk. This is the idea that it is a good idea to
put all your eggs in one basket. More on
the concept later, but I wanted to address the impact of diversification on
commissions here.
Different experts (and I will use the term loosely)
recommend different numbers of stocks to be diversified, but for our example we
will use five. Assume a starting
portfolio of $10,000, a not insignificant sum for most people. In order to purchase five stocks at $8 per
buy, the investor is down $40 from the get-go.
Of course, in order to unwind the positions, that is, sell the stocks,
he will have to pay another $40.
Diversification has cost him $80, or 0.8%, He could have put all $10,000 in one stock
and been better off even if the stock went down in value by one half of one
percent.
Whatever the benefits of diversification, and there is some debate
on the value, it does create a financial hole that the investor has to dig out
of. It may be better to put all of your
eggs in one basket if the cost of buying many baskets is going to cause you to
go broke anyway.
