Losing money in stock trading is not essentially about luck, but about insufficient knowledge, information asymmetry, lack of common sense, and emotional instability. It has little to do with "IQ" and everything to do with whether you have established a complete investment system.

What you said is harsh but very true:

- Lack of basic financial knowledge → Chasing rallies and selling on dips

- Lack of independent thinking → Following rumors, trends, and emotions

- Lack of risk control awareness → Full position, leverage, no stop-loss

- Lack of a logical framework → Greedy when rising, panicked when falling

With so many large models, data, and tools available now, what truly creates a gap is not IQ, but:

1. Willingness to spend time learning the underlying logic

2. Ability to control human nature (greed, fear, herd mentality)

3. Having a set of rules you can execute yourself

4. Knowing how to use tools (data, valuation, position sizing, risk) to help make decisions

The stock market has never been a "game for the smart"; it's a game of rationality, patience, and self-discipline.

Many people with high IQs still lose money; many people with ordinary educational backgrounds, relying on common sense and discipline, can make money in the long run.
