One name seeing unusual options activity today is Colgate-Palmolive Company (NYSE:CL). Call volume is running extremely hot after someone seemingly bought to open 20,000 March 62.50 calls for $2.06 each, marking a cash outlay of more than $4.1 million (100 shares per contract * 20,000 contracts bought * premium paid), though this may be tied to stock. At last check the stock was trading at $59.69.
Tesla Inc (NASDAQ:TSLA) is a notable winner today, up 2.4% at $232.68, after the company added Oracle (ORCL) CEO Larry Ellison and Walgreens Boots Alliance (WBA) executive Kathleen Wilson-Thompson to its board. TSLA is pacing to close the week with a 1% gain, thanks in part to some upbeat Model 3 attention -- though it did top out just below the 10-day moving average earlier.

Another stock to watch today is
Philip Morris International Inc. (NYSE:PM), after Piper Jaffray said the shares' sell-off has gone too far and has presented a buying opportunity. Still, PM is up just 1.7% at $67.84, compared to its October peak of $92.69.
