The S&P500 could see higher volatility upon the release of the November FOMC meeting minutes on Wednesday, which should offer insights into how the Fed is thinking about the path of rate increases. Tech companies HP and Dell (today in after-hours) will report earnings, offering a glimpse of the state of demand for PCs. And retailers Best Buy and Dollar Tree will report earnings, ahead of "Black Friday", which is historically one of the year's biggest shopping days. This morning S&P500 futures are lower as the number of China Covid cases jumped over the weekend, worrying traders about the global growth outlook.
