What is a One-Night-Stand Investment?

Most investors have made decisions that they eventually regret. One-night-stand investments are simply decisions that investors regret sooner rather than later, turning what are supposed to be long-term investments into short-term ones. What causes the regret can vary widely: putting too much of one's portfolio in an investment, hearing bad news about the investment, and not delivering up to earnings expectations are some examples.

One-night-stand investments are a topic that behavioral finance researchers often study.

The next day, John speaks to his financial advisor, who can't believe that he fell for such a terrible sales job. He urges John to get out of the stock, and he does. John's investment in the beverage company is a one-night-stand investment.
