The company averages 437 option contracts a day - already nearly 7,000 have traded just an hour into the day. 6,800+ have been calls - a 253:1 call to put ratio. The Feb 12.5 calls are the action. Over 6,700 have been purchased on essentially no open interest (OI) - these are opening order purchases. Vol is up on call purchases - the skew is changing shape from the classic volatility smile (smirk) to an upward curving smile. The demand for the calls is going up --> that means vol is going up. This is "irregular" but not "uncommon" when one line continues to trade on the offer.
