1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The weekly market declined to varying degrees, with all three option underlying assets dropping by over 1%. The changes in the position PCR ratios showed divergence, with the position PCR of 50ETF and 300ETF continuing to fall, while the put contract position ratio of 500ETF increased. Considering the changes in the implied volatility curve structure, with the curve of 500ETF shifting to the left, indicating some cautious sentiment, it is believed that the current market risk preference level has decreased, and a cautious attitude towards small-cap growth stocks is recommended.
