Things to remeber
- When a buyer seeks to buy a stock, the willingness of other participants to sell the same stock suggests that they value stock differently. As such we need to have more reliable information.
- Familiarity bias - investors favor investments in companies they are familiar with.
- Overconfidence bias - investors trade too much.
- Disposition effect - Investors tend to hold on to stocks that have lost value and sell stocks that have risen in value since the time of purchase(tendency to hang on to losers and sell winners).
People hate to think about bad things happening, so they always underestimate their likelihood.
