Investing in stocks is risky. Stocks that rise sharply in the short term are often affected by market sentiment, industry dynamics and company fundamentals, and are difficult to accurately predict. Here are some suggestions to help you improve the accuracy of your investment judgment: 1. **Pay attention to market dynamics**: Pay attention to economic data releases, industry news, company financial reports, etc., which may affect stock prices. 2. **Technical analysis**: Learn technical analysis tools, such as moving averages, relative strength indicators (RSI), etc. These tools can help you identify potential buying and selling opportunities. 3. **Hot industries**: Pay attention to hot industries in the current market, such as technology, green energy, artificial intelligence, etc., usually excellent companies in these industries have greater growth potential. 4. **Company fundamentals**: Choose companies with good financial conditions and great profit growth potential, especially some undervalued stocks. 5. **Social media and forums**: Pay attention to hot stocks discussed on social media and investment forums. Sometimes market sentiment can affect stock prices. Please remember that short-term investments are risky. It is recommended that you do more research and evaluation, and consider consulting a professional financial advisor. If you decide to invest, make sure to only invest funds that you can afford to lose.
