The Shanghai SSE composite index is now below 2320, the lowest since the amazing run up started in 2006. The index is off over 60% from the peak.



This is a stunning stock market crash. Usually a stock market crash leads to less business investment, and an economic slowdown.



The second graph compares the NASDAQ (as a percent from the peak) to changes in business investment in structures and software and equipment.



This shows that business investment in both categories went negative about 3 quarters after the stock market peaked. Of course there are major differences between the U.S. and China, but I'd expect business investment to slow in China.
