How to select strong stocks? After multiple反复 (repeated experiences), I've concluded that 'chart patterns' are more reliable than 'concepts'. Guosen Technology is the best example.

I used to chase 'concepts'—every day, various so-called 'hot concepts' would see their stocks surge to the daily limit, which looked exciting, but real trading always brought problems, mainly due to the following reasons:

1. A single stock can belong to multiple concepts, making it hard to determine which one is dominant.

2. Different apps define the same stock's concepts differently, so it's impossible to know which app is accurate.

3. There are many stocks in hot concept categories, but whether to buy or sell still ultimately depends on chart patterns—concepts don't really help.

Based on the above, I no longer blindly follow 'concepts'—I only focus on chart patterns.

The stock in the chart is Guosen Technology. It's not found in any of the hottest sectors recently, yet it keeps hitting the daily limit. If I had to assign it a concept, it would undoubtedly be 'limit-up stock'.
