In today's ever-more interrelated financial world, China's stock-market action is growing increasingly influential everywhere else. As the globe spins, the results of each day's stock trading in China often spill over into Europe and then the States to affect sentiment. This impact is universal, but especially pronounced in sectors China plays a major role in like commodities stocks. Interestingly, the recent breakdown in the US stock markets in late June was the latest example of this China-driven sentiment bleedover. On Monday June 28th, the flagship S&P 500 stock index (SPX) here in the States remained well above its correction lows from 3 weeks earlier. But as China's stock markets opened the next morning, a US non-profit organization released a downward revision in its brand-new index of leading economic indicators for China. It claimed it had made "a calculation error" weeks earlier. The reaction in Shanghai was fast and furious, China's flagship Shanghai Stock Exchange Composite Index (SSEC) plunged 4.3% on Tuesday the 29th. It was this index's worst selloff by far in nearly 6 weeks. Later that same day, this ugly Chinese sentiment spilled over into the States and drove a 3.1% SPX selloff. Not only was this the worst US down day since just before the correction bounced in early June, but it drove the SPX to fresh new correction lows. This led to more selling in the following days. And when that "news" alleging a slowing Chinese economy hit, commodities stocks bore the brunt of the selling pressure worldwide
