Golf And Investing

A recent article discusses how golf and investing may be related, but also talks about several behavioral biases that can affect investors. For example, loss aversion shows up in golf as golfers are more likely to make a putt of the same difficulty for par than they are to make the putt for birdie (one under par). Another behavioral bias discussed is probability neglect, that is, people tend to worry about bad outcomes that have a very low probability, such as a plane crash or losing 40 percent of their investment. By overweighting events with a low probability, investors can incur large opportunity costs. Finally, an informational cascade occurs when investors believe the signals from other investors, even if they do not agree. For example, if a stock you view positively begins to drop, you may sell based off what other investors are doing, rather than what your research has revealed to you. As the article notes, smart investors aren't loss averse, they don't neglect probability, and believe in their own analysis.
