You already know that frictional expenses can make buying and selling stock in rapid-trading fashion seriously lower your returns.

Still, there are times when you may want to part with one of your stock positions.

How do you know when it’s time to say goodbye to a favorite stock?

These helpful tips can make the call easier.

-Earnings were not properly stated.

-Debt is growing too rapidly.

-New competition is likely to seriously harm the firm’s profitability or competitive position in the marketplace.

-Management’s ethics are questionable. Benjamin Graham said that “you cannot make a quantitative adjustment for unscrupulous management, only avoid it.” In other words, it doesn’t matter how cheap a stock is, if the executives are crooks, you are likely to get burned.

-The industry as a whole is doomed due to a commoditization of the product line.

-The market price of the stock has risen far faster than the underlying diluted earnings per share. Over time, this situation is not sustainable.

-You need the money in the near future – a few years or less. Although stocks are a marvelous long-term investment, short-term volatility can cause you to sell out an inopportune moment, locking in losses. Instead, park your cash in a safe investment such as a bank account or a money market fund.

-You don’t understand the business, what it does, or how it makes money.

One important note: History has shown that it is generally not a good idea to sell because of your expectations for macroeconomic conditions, such as the national unemployment rate or the government’s budget deficit, or because you expect the stock market to decline in the short-term.
