Today’s tickers: VRTX, ZQK & JPM VRTX  - Vertex Pharmaceuticals, Inc. –  A sizable bullish position initiated in Vertex options this morning looks for shares in the drug maker to regain some of the steep losses realized during the past two months. Shares in Vertex Pharmaceuticals are trading flat on the session at $39.10 as of 11:20 a.m. ET, but have dropped 35% since the second week in October. One options trader who appears to have purchased a 3,500-lot April $42/$55 call spread for a net premium of $2.66 per contract stands ready to profit from a strong rebound in Vertex shares through expiration. The spread starts making money if shares increase 14% over the current price of $39.10 to surpass the effective breakeven point at $44.66, with maximum potential profits of $10.34 per contract available in the event shares jump 41% to hit $55.00 by expiration in April. ZQK  - Quiksilver, Inc. –  Options on apparel and accessories retailer, Quiksilver, Inc., are more active than usual on Friday ahead of the company’s fourth-quarter earnings report next week. Shares in the maker of casual wear under its Quiksilver, Roxy and DC brands are trading up 2% today at $4.09 as of midday on the East Coast. Traders exchanged more than 7,500 option contracts on ZQK during the first half of the session, sizable volume versus the stock’s average daily options volume of around 1,300 contracts. The Dec. $5.0 strike calls are seeing the heaviest trading traffic, with more than 4,200 lots in play against zero open positions. It looks like most of these calls were purchased for an average premium of $0.05 apiece, perhaps by one or more strategists expecting the price of the underlying to pop after earnings. The stock posted double-digit percentage gains following the release of third-quarter earnings in September and after the second-quarter earnings report in April of this year. Buyers of the $5.0 strike front month call options on ZQK this morning may profit at expiration should shares in the name rally nearly 25% to top the breakeven price of $5.05.…
