WHEN
YOU DECIDE THAT YOU MADE A MISTAKE IN BUYING IT IN THE FIRST PLACE:
This happens. You find yourself wondering what
you were thinking, or why did you listen to that person’s advice,
etc. Once you know it was a mistake, sell and move on.
WHEN
YOUR SECURITY HAS REACHED YOUR PREDETERMINED SELLING PRICE (FOR PROFIT
OR LOSS):
In this case you had a sell strategy in place at
the time you made the purchase, which is a good idea. A common strategy
is to sell if your security loses 20% of its value, but you could
use a different percentage as your trigger. Some people actually put
in their sell order immediately after making the purchase, using a
stop loss price to trigger the sell if the stock goes down to that
limit. (Read up on this procedure before you try it.) You could also
subscribe to the philosophy of automatically selling any security
that has achieved a certain amount of profit. In any case, if you
have a strategy in place for selling, you should be consistent with
it.
Do not be deterred from selling because you are hoping the price will
recover to at least your purchase price. This is probably the most
common error: holding onto a loser with the hopes of achieving 0%
return on your investment. When it’s obvious the stock is “dead
money,” go ahead and sell so that you can put that money to
work profitably.
WHEN
YOUR OPINION ON THE OUTLOOK FOR THE SECURITY, THE MARKET, OR THE ECONOMY
HAS CHANGED:
Hopefully you make investments based on sound reasoning.
But things can change. If fundamentals change at a company you own,
or an industry sector goes out of favor, selling that company or companies
in that sector could benefit your portfolio. Of course, this can be
a very hard call. You have to decide if this change is temporary and
fixable, or is it a harbinger of worse things to come. Do not put
off assessing the situation.
WHEN
YOU NEED THE MONEY FOR SOMETHING ELSE:
This reason is the easiest to identify. If you
need to take money out of your investment portfolio, sell the weakest
of your holdings: the stock(s) with deteriorating fundamentals, not
your winners. When you find another investment that meets your criteria
as a good investment, and it is a good time to buy this new investment,
but you don’t have the buying power, sell your weakest holding(s)
to raise enough money to buy that something better.
