For ordinary retail investors, the most pragmatic choice is to buy and hold patiently. Frequent trading and short-term speculation often end in losses. It is very difficult to compete with institutional funds and platform algorithms, and you are more likely to be overwhelmed by market sentiment. Be especially cautious of extreme actions—don't easily short, because history has shown that this is usually not a game for retail investors.

Let's look at two typical examples from the US stock market: one is the bullish side represented by Warren Buffett, who mostly坚持投资持有, with only a few times of cashing out in his decades-long career. Each time he was waiting carefully for a lower entry point. It is this restraint and patience that have allowed his team to accumulate assets worth trillions.

On the other side are short-sellers like Bill Gates—who once held enormous wealth but missed many upward cycles due to being bearish. The long-term performance difference between these two styles speaks for itself. For retail investors with limited funds, adopting a bullish mindset and holding long-term is often more practical than trying to predict market bottoms and trading frequently.
