Group 1 - The core idea is that retail investors can outperform other retail investors by avoiding common pitfalls and leveraging them as tools for success [1] - Retail investors often panic and sell when a stock drops by 5%, but hold on when it drops by 10%, while they tend to sell too early when a stock rises by 2% [1] - Establishing a "stop-loss line" for each stock is crucial, such as selling if it drops below the 20-day moving average or more than 15% in a week [1] Group 2 - The focus in a bull market should be on trends rather than daily fluctuations, as many sectors experience rotation [1] - Retail investors should select solid stocks in sectors with policy support, such as new energy and semiconductors, and minimize daily monitoring [1] - Avoiding the urge to trade based on daily market movements can help reduce transaction costs and improve profitability [1] Group 3 - Retail investors often react to news, entering positions based on perceived good news, which can lead to losses as institutional investors may sell at that time [1] - It is more effective to focus on price trends and volume rather than news, as consistent price movement along moving averages indicates genuine buying interest [1] - The key to success in a bull market for retail investors is to act contrary to the crowd: remain calm when others panic, wait when others rush to cash out, and focus on trends rather than news [1]
