Yuegangwan Holdings and Weichai Power both fell by two to three percentage points. The traditional chemical and industrial manufacturing sectors in the Hong Kong stock market followed the broader market's fluctuations. 3M rose by over four percentage points, with the old-line defensive materials sector in the U.S. stock market strengthening against the trend. Both are industrial materials, but the defensive attributes of the U.S. stock market are reflected in the return curve, while cyclical stocks in the Hong Kong market bear the brunt of the volatility first.
