Among the stocks with unusual put volume is gambling giant

Trade-Alert. This represents a break from the norm, as LVS option traders have been

Microblogging issue Twitter Inc (NYSE:TWTR) is one of the worst performers on the Big Board today, down 6.7% at $16.71 -- and giving up all of yesterday's gains. Sparking the sharp sell-off is a bearish note from Stifel Nicolaus, which cited slowing growth and a "lack of product innovation" for its negative outlook.

The leading advancer on the Nasdaq is catheter concern Hansen Medical, Inc. (NASDAQ:HNSN), which has surged nearly 32% to $4.22. A nod from the Food and Drug Administration (FDA) is boosting the stock, and sending its options volume through the roof.
The
CBOE Volatility Index (VIX) has jumped 1.4 points, or 6.9%, at 21.36.
Today's put/call volume ratio on the SPDR S&P 500 ETF Trust (SPY) is 1.18, with puts outstripping calls. At last check, SPY has lost 2.5 points, or 1.3%, at $191.12.
