Opportunity Cost
There’s one other type of risk that the exam may ask about: the concept of opportunity cost. This is the idea that every choice investors make to invest their money somewhere potentially represents hundreds (even thousands) of other choices that they could have made to invest somewhere else but didn’t. It’s the risk of not having made the best choice. In other words, which opportunities are you missing out on by investing in a certain security?
An illustration of the concept is to think of a teenager at the mall with $20 in his pocket. If he decides to spend that entire $20 on chocolate, that is $20 he cannot spend on a movie, toys, clothes, or other types of candy. All those other options for which the teenager could have used his money represent the opportunity cost of spending his $20 on chocolate.
