1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Today, all stock indices showed narrow - range oscillatory corrections. Recently, the trading volume of the stock market has been shrinking, indicating an increase in market wait - and - see sentiment and a weakening of investors' risk appetite. The main logic supporting the stock market has cooled down. On one hand, the marginal benefits of incremental policies have weakened. On the other hand, the valuation repair of technology stocks has come to an end. The market is entering the earnings disclosure season, and the realistic logic of earnings verification is heating up. Additionally, technology stocks have achieved significant gains, increasing investors' willingness to take profits and bringing short - term technical adjustment pressure. In general, in the short term, market sentiment is inclined to wait - and - see, and stock indices will mainly oscillate within a range. Due to the high possibility of short - term stock index oscillations, for options, one can hold bull spreads or sell covered calls [3] 3.
