Summary by Directory 3.1 Market Views - **Stock Index Futures**: On Tuesday, the sentiment in the equity market was weak, with sectors like computer, media, and new energy leading the decline, and only the dividend index being resilient. The factors contributing to the pullback are the sharp decline of Bitcoin against the US dollar on December 1st and the historical value - oriented style in December. Although it's unlikely to fall below the November low, the market is expected to be volatile in December, being stable before major meetings and facing risks in the second half of December. The recommended operation is to hold IM + dividend [1][7]. - **Stock Index Options**: On Tuesday, the trading volume of financial options decreased, and the implied volatility of each variety showed differentiation. The skewness remained at a high level, and the PCR of open interest decreased slightly, indicating weak market sentiment.
