# [True Insight Institutional View] U.S. stocks showed mixed performance, Hang Seng Index tests support at 10-day moving average

The three major U.S. stock indices showed mixed performance, with the Dow and S&P 500 slightly down but with limited losses, while the Nasdaq rose slightly by 0.03%. The Golden Dragon Index, reflecting the performance of Chinese concept stocks, also rose slightly by 0.12%.

As for the Chinese and Hong Kong stock markets, after hitting a new high for the year last week, A-shares continued to perform well yesterday. The Shenzhen Component Index once hit a nearly two-year high during the session, while the Shanghai Composite Index even reached a 10-year high. At the close, the Shenzhen Component Index rose 1.73% to 11,835 points, and the Shanghai Composite Index also rose 0.85% to 3,728 points, both setting new closing highs for the year. The trading volume exceeded 2.8 trillion yuan. Hong Kong stocks rose and then fell back yesterday, with relatively volatile performance in the early session. In the afternoon, it once surged to 25,466 points, but failed to sustain the gains in the final session, closing at the day's low of 25,176 points, down 93 points or 0.37%. The Hang Seng Tech Index maintained its upward trend, closing at 5,579 points, up 0.65%, with a total trading volume of 312.8 billion yuan. Among the constituent stocks, JD Health (06618.HK) performed the best, rising more than 8.4%, while Ali Health (00241.HK) also rose 3.6%. Auto stocks also rebounded, with Geely Auto (00175.HK) rising nearly 3% and Li Auto (02015.HK) up 1.2%. Tingyi (00322.HK) was the worst-performing constituent stock, falling more than 3.2%, while mainland property stocks also faced selling pressure, with Longfor (00960.HK) and China Resources Land (01109.HK) both falling more than 3%.

The Hang Seng Index has now fallen back to near the 10-day (25,121 points) and 20-day (25,160 points) moving averages. As long as it does not fall below these levels, the upward trend is expected to continue. However, if it falls below, the market may need to further test the 50-day moving average at around 24,550 points.
