Report Investment Ratings - Stock index: ☆☆☆ [1] - Treasury bond: ☆☆☆ [1] Core Views - As of the week ending September 19, the stock index rebounded slightly after a brief shock last week, with some indices hitting new highs, but individual stock performance diverged. The risk - free rate has rebounded, but the capital side remains loose, and trading volume and margin trading leverage continue to rise. Foreign investors may still have a high level of attention to the A - share market, and foreign futures member seats are still in the stage of increasing positions, indicating that market risk appetite may still be high [1]. - From the high - frequency macro - fundamental factor scores, for stock index futures, the inflation indicator scored 7 points, the liquidity indicator scored 9 points, the valuation indicator scored 11 points, and the market sentiment indicator scored 9 points. For treasury bond futures, the inflation indicator scored 8 points, the liquidity indicator scored 11 points, and the market sentiment indicator scored 7 points [1]. - In terms of the term structure, the discount of stock index futures narrowed rapidly last week, and the near - month contracts of IF, IH, and IC all showed premiums, indicating strong bullish sentiment. However, the December contracts of IC and IM still had a large discount [1]. - The net value of the financial derivatives quantitative CTA strategy increased by 0.45% last week, with profits coming from opening and closing a long position in TF on Wednesday. In the long - term, fixed - asset investment and social retail consumption were both lower than expected, and the overall economic data in August exerted significant pressure on stock index futures, while the rebound of treasury bond futures was not significant. In the short - term, the continuous decline of the US dollar index increased the contribution of the exchange rate to stock index futures. Currently, the capital side remains relatively loose, the margin trading balance remains high, and the overall market risk appetite remains high [1]. - In terms of open interest, the open interest of IC and IM decreased marginally, while that of IF and IH remained relatively neutral. The overall comprehensive signal was neutral and oscillating. For treasury bond futures, although the capital side remained loose, market risk appetite limited the upward space, the stock - bond seesaw effect decreased, the open - interest factor weakened marginally, and institutions were still cautious about allocation behavior, with the comprehensive signal being neutral and oscillating [1].
