Don't research too many stocks, the key to making money is these 5 points:

1. Earnings must be solid — P/E ratio should not exceed 15, and annual earnings per share should be at least 0.2 yuan.

2. Position must be correct — Stock price must be above the annual moving average; avoid stocks below it.

3. Size must be moderate — Choose fully tradable stocks with a market cap between 5-50 billion yuan.

4. Background must be reliable — Top 10 shareholders should include institutions or foreign investors, not just retail investors.

5. Trend must be upward — Moving averages should be in a bullish alignment, and the stock price should be above the 20-day moving average before considering a buy.

In short: Look for stocks with solid fundamentals, strong technicals, and institutional interest. The simplest path is often the best — less tinkering is the survival strategy for retail investors.
