Short - term Outlook - In the short term, the market style differentiation is expected to continue. The SSE 50 Index corresponding to IH is expected to be relatively resistant to decline due to the defensive properties of large - financial and low - valuation blue - chips and the policy expectations of weight sectors.

The small - and medium - cap indexes corresponding to IC and IM are volatile in the short term due to the sentiment of growth sectors, but the CSI 500 Index has long - term allocation value and may have structural opportunities after short - term adjustment [4].
