Some sectors indeed become hot topics throughout the year, but there's an important point — the market won't let you reap the benefits of a sector for 12 consecutive months. Do you understand? It happens in phases. After the first wave of the trend completes, there's a 1 to 3 month correction period, then the second wave begins, often more vigorous than the first.

Missed the first wave? Don't be disappointed. There will still be opportunities to jump on the next wave. The key is to understand this cycle logic — chasing the high can easily lead to being trapped, but those who understand how to switch waves can always find entry points at certain stages. Every day in the exchange, someone says "I wish I had known earlier," but in reality, the opportunity has always been there, as long as you're not impatient.
