The
Dow Jones Industrial Average (DJIA) plunged nearly 1,100 points at the open -- hitting an annual low of 15,370.33 along the way -- but has since pared these losses to 232 points. The
S&P 500 Index (SPX), meanwhile, was off triple digits at one point, while the
Nasdaq Composite (COMP) plummeted to its lowest level since last October. Combining last week's drubbing --

Among the stocks with notable option activity is Bank of America Corp (NYSE:BAC), with the contracts crossing at two times the average intraday pace. Calls are outpacing puts by a 2-to-1 margin, and it looks like one trader opened a block of 16,760 weekly 9/4 16.50-strike calls for $0.21 apiece. The stock is off 1.5% at $15.86 -- and earlier hit an annual low of $14.60 -- despite some upbeat attention from the brokerage bunch.
One of the top losers on the Big Board is China-based Alibaba Group Holding Ltd (NYSE:BABA). The e-commerce concern is down 2.1% at $66.74 -- after falling to a record low of $58, its first foray south of its IPO price to date.
One of the biggest decliners on the Nasdaq is Omeros Corporation (NASDAQ:OMER), down 13.2% to churn near $18.19. Just last week, the stock soared to all-time highs thanks to well-received drug data. The stock is now testing a foothold atop its 10-day moving average.

The CBOE Volatility Index (VIX) is up 5.7 points, or 20.4%, at 33.76 -- and earlier hit a six-year peak of 53.29.
