1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - On January 29, 2026, stock indices showed volatile differentiation. The SSE 50 Index led the gains, while the CSI 500 and CSI 1000 Indices rose first and then fell. The total trading volume of the Shanghai, Shenzhen, and Beijing stock exchanges was 325.94 billion yuan, an increase of 26.71 billion yuan from the previous day. In the short term, the driving force for the upward movement of stock indices has weakened, and there is a high demand for the CSI 500 and CSI 1000 Indices, which have had large previous gains, to consolidate through fluctuations. The defensive nature of the SSE 50 Index has attracted capital attention. In the medium to long term, positive policy expectations and the continuous net inflow of incremental funds into the stock market are the main supporting forces for the upward movement of stock indices. Overall, stock indices are likely to fluctuate and consolidate in the short term. For options, considering the relatively solid medium - to long - term upward logic of stock indices, a bull spread strategy can be adopted [4]. 3.

The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 3.1181 trillion yuan, an increase of 401.7 billion yuan from the previous day [4]. - The positive policy expectations and the continuous net - inflow of incremental funds into the stock market are the main supporting forces for the upward movement of the stock index. These two factors remain unchanged in the medium and long term, and the logic of the medium - and long - term upward movement of the stock index is relatively solid [4]. - In the short term, the policy support needs, the promotion of technological innovation, and the expectation of boosting consumption are relatively clear, which strongly support the stock index.

In general, the stock index will mainly fluctuate and consolidate in the short term [4]. - Regarding options, since the medium - and long - term upward logic of the stock index is relatively solid, a bull spread strategy can be considered [4]. 3.

1. Report Industry Investment Rating - No relevant content provided. 2. Core Viewpoints of the Report - Today, the stock indices showed mixed trends. The CSI 1000 and CSI 500 rose significantly, while the SSE 50 and CSI 300 fluctuated within a narrow range. The total stock market turnover was 1897.2 billion yuan, a decrease of 24.1 billion yuan from the previous day. The power equipment, commercial space, consumer electronics, and liquid - cooled server sectors led the gains, which was favorable for small - and medium - cap indices. The stock market is still in a sector rotation market, with the overall trading volume not significantly increasing. Active funds are concentrated in high - growth sectors, resulting in a structural differentiation of the indices. In the long - term, positive policy expectations and the inflow of funds form the long - term support for the indices. In the short - term, as the end of the year approaches, the liquidity of funds has tightened, and the incremental policy signals are not clear, so the short - term upward driving force of the stock indices is insufficient. Overall, the stock indices will maintain a range - bound trend in the short - term [3]. - Currently, both the PCR of open interest and the implied volatility are within the normal range. A bull spread or ratio spread strategy with a mild bullish view can be adopted for options trading [3]. 3.
