Now, imagine that you decide to buy the stocks of those five companies with your $1,000. To do this, you will incur $50 in trading costs—assuming the fee is $10—which is equivalent to 5% of your $1,000. If you were to fully invest the $1,000, your account would be reduced to $950 after trading costs. This represents a 5% loss before your investments even have a chance to earn.
Risk tolerance is also affected by one’s perception of the risk. For example, flying in an airplane or riding in a car would have been perceived as very risky in the early 1900s, but less so today as flight and automobile travel are common occurrences. Conversely, most people today would feel that riding a horse might be dangerous with a good chance of falling or being bucked off because few people are around horses.
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.
