The biotech sector, from a technical perspective, indeed presents an opportunity for increased positions on the left side. But it depends on your own mindset—if you're risk-averse, you can follow the approach from the previous two times: wait until the decline is sufficient and the rebound begins before entering the market. This way, you avoid eating the top or the bottom, and you'll feel much more comfortable.

If you think you can earn a little more on the left side, then consider opening and adding to your positions in batches. Follow the rhythm of "buying one layer after a two-layer decline," rolling through 3 to 5 layers, which is enough—there's no need to go all-in at once. This way, you can participate in opportunities without risking too much by going all-in. The key is to operate according to your own risk tolerance and avoid blindly following the trend.
