Due to the intertwined bullish and bearish factors, it is difficult for investors to time the market, and using linear profit - loss tools for asset allocation bears high volatility risks [1] - The CSI 1000 Index is likely to fluctuate in the short term because although there are positive policy expectations and continuous capital inflows, there is still a need for short - term technical consolidation due to the significant increase in stock valuations [5] Option Indicators - As of November 6, the position PCR of CSI 1000 index options was 108.90%, at the 96.0% quantile level since 2023, indicating that the proportion of non - bearish investors in the market is at a relatively high historical quantile, and the market sentiment is generally positive [3] - Since late October, the at - the - money implied volatility of CSI 1000 index options has continued to decline.

The active margin trading funds can attract more investors to enter the market [10] - Resident wealth management funds, institutional medium - and long - term funds, and foreign capital are continuously flowing into the stock market.

Taking the call bull spread as an example, this strategy is suitable for a moderately bullish market, with limited maximum losses and the potential to accumulate floating profits when the index rises [11][13]

1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints of the Report - Short - term, stock indices will maintain range - bound oscillations. Currently, the market is in a stage where the rhythm of policy - driven positive expectations and the rhythm of profit - taking by funds are in a tug - of - war. In the medium to long term, policy - driven positive expectations and the trend of net capital inflows into the stock market provide strong support for stock indices. However, in November, the incremental signals from the policy side have weakened, and although external risk factors have eased, uncertainties still remain, limiting the upward driving force of stock indices. With the significant increase in the valuation of stocks, the demand for profit - taking by profitable funds has risen, and there is still a need for technical consolidation of stock indices [3][9][84]. - The implied volatility of ETF options and stock index options is at a relatively low level. Considering that the stock indices are expected to rise in the medium to long term, it is advisable to maintain a mild bullish stance through bull spreads or ratio spreads [4][85]. 3.
