First, lack of risk awareness. The stock market should be cautious and risky when entering the market. Most investors tend to put risks behind them, value immediate interests, and like to chase up and kill down. Second, the lack of awareness of asset allocation. Some investments have always been linked to the higher expected risk of income, and putting an egg in the same basket does not understand the risk dispersion. Third, blind investment, even the companies they invest in don't know what they do. By feeling investment, I feel that the investment risk is very small, so I keep increasing my investment until I exceed the tolerance limit, and the higher the risk, the greater the risk.

Fourth, listen to others to make investments. Careless and irrational. Buffett's book emphasizes that the premise of successful investment is rational thinking and one's own personality. Investment must be rational. If you can't understand, then don't do it. Why talk about rationality? Because the stock market is to put aside emotions and not let emotions dominate everything. People are in an irrational state when manipulating, and always feel that they are very talented and talented in stock trading. Only reason can see the reality clearly.

Fifth, always buy or buy when investing. Instead of making money, it will make you lose money. Your ordinary transaction will only increase the income of the fund manager, instead of making your wallet swell, it will shrink.

Sixth, pay too much attention to financial news and listen to investment experts for fear of missing the market. If an investment expert makes money in the stock market, he will stop working.

Seventh, excessive self-doubt, lack of self-confidence, fear and greed.
