Closing changes for the main US markets:
- S&P 500 -0.6%
- Nasdaq composite -0.8%
- Russell 2000 -1.7%
- DJIA -0.4%
On the week:
- S&P 500 -4.8% -- worst since week ending June 17
- Nasdaq composite -5.5%
- Russell 2000 -4.9%
- DJIA -4.1%
Now for more bad news: There's an outside bearish reversal on the weekly chart of the S&P 500 (and the Nasdaq as well).
If that's not bad enough, next week is the worst week on the calendar seasonally for equities, over the past 50 years.
