Risk tolerance is a psychological trait that is genetically based, but positively influenced by education, income, and wealth (as these increase, risk tolerance appears to increase slightly) and negatively by age (as one gets older, risk tolerance decreases).

In psychological terms, risk tolerance is defined as “the extent to which a person chooses to risk experiencing a less favorable outcome in the pursuit of a more favorable outcome.” In other words, would you risk $100 to win $1,000?

What would make me sell: Sometimes there are good reasons to split up. For this part of your journal, compose an investing prenup that spells out what would drive you to sell the stock. We’re not talking about stock price movement, especially not short term, but fundamental changes to the business that affect its ability to grow over the long term. Some examples: The company loses a major customer, the CEO’s successor starts taking the business in a different direction, a major viable competitor emerges, or your investing thesis doesn’t pan out after a reasonable period of time.
