McDermott International Inc (NYSE:MDR) is seeing unusual options volume today, with roughly 12,000 calls across the tape so far -- nearly seven times the average intraday volume. The January 2020 10-strike call is by far the most popular, with most positions likely being bought to open. MDR stock is up 10.8% at $10.13, after the oil concern inked a contract with Qatargas.
One of the top performers today is Rexan Pharmaceuticals Inc (NYSEAMERICAN:RNN), on a pancreatic cancer drug development and commercialization agreement with BioSense Global. The pharma stock is up 42.5% at $7.64, at last check, and earlier traded as high as $9.14. RNN is pacing for its best day since 2014, but is still set to close beneath its 80-day moving average -- a trendline not tackled since before a late-January bull gap.

Wave Life Sciences Ltd (NASDAQ:WVE) is one of the underperformers on the Nasdaq today, on poorly received data for its muscular dystrophy treatment. WVE shares have plummeted 28% to $24.48, at last check, and earlier touched a new annual low of $22.90.
