Pre-market plan for today:

Plan to buy $Direxion FTSE China Bear 3X(YANG.US) in batches during the mid-session today and tomorrow, with the price controlled between 20.70-21.5. This is a point with an extremely high win rate, but the possibility of Hong Kong's Spring Festival market cannot be ruled out, which may lock or trap the position for a longer time. However, it can be confirmed that there is a profit probability of over 95%.

Monitor $Baidu(BIDU.US) and wait for short-selling opportunities. There should be a profit of over 10 yuan per share, with multiple operations. Conservatively estimated, the profit can reach 15-20%.

Monitor the post-earnings trend of $Sandisk(SNDK.US) $Western Digital(WDC.US). There may be a pullback, so short briefly and then go long. However, it is unlikely to participate in Western Digital. The reason for not betting on its earnings is the high risk—a 50% chance of choosing the wrong direction. Even if the position is unwound later, it will still be a loss because it wastes the time cost of profitable capital.

Monitor the earnings of $NVIDIA(NVDA.US) and look for opportunities to bet on earnings options. There may be a 15-20% return on the total capital invested.

Seize the opportunity to act, and don't operate blindly or based on feelings just because you're bored. These are behaviors that lack reverence for the stock market.
