If riding a bucking bronco is your idea of fun, you’re going to love what the stock market has in store. Consider this past week’s ride a preview.The week’s action didn’t look like much, if you didn’t know better. The Dow Jones Industrial Average rose 213.12 points or 0.6%, while the S&P 500 advanced 0.5%, and the Nasdaq Composite ended little changed.
The S&P 500 slumped 1.8% on Monday and Tuesday, thanks to China Evergrande, the Chinese property company that looks like it is ready to default on its more-than $300 billion in debt. Cries of the next Lehman Brothers—or maybe the next Silverado?—echoed through the canyons of Wall Street as investors prepared for the worst.
