The market hit a low of 87564 early in the session and then began a strong rebound. The overall market's large B-wave rebound structure is developing into a complex pattern. This week, many factors are affecting the market, including economic data and monetary policies, especially Japan's interest rate hikes, which will cause significant volatility and restrict upward space. For this rebound to be strong and sustainable, it must break and stabilize above 91117 to open up further upward potential; otherwise, the market will continue to fluctuate sharply below that level. In the short term, as long as the price does not effectively break below 87366, there is still a chance for the market to push higher towards 93000. However, after breaking above 91117, it is advisable to encounter resistance and mainly take short positions, avoiding chasing the rally. The trend is nearing its end, and even if there is an upward surge, it will be the last opportunity.
