Carnival Cruise (CCL) shares are sinking today and implied volatility in the options on the stock is moving higher in the wake of the Italian cruise ship disaster off the coast of Tuscany. CCL is down $4.73 to $29.55 and morning trades on the stock include a multi-exchange sweep of 2650 Jun 30 puts at $2.60 when the market was $2.60 to $2.70. Data from one exchange is hinting at opening sellers. Feb 30 calls on the stock were actively traded early and seem to include a mix of action. 3332 traded (53 percent Ask) and the flow includes a sweep of 757 contracts at the $1.20 asking price, to open. However, the top trades in CCL are a Jan 27 – 32 put spread, sold at $2.30, 10000X and tied to 820K shares at $29.65, which is possibly a closing trade from mid-Nov (see 11/15 color) after the volatile move in the stock and ahead of this week’s expiration. Still, implied volatiilty in CCL has rallied 47.5 percent to 41, as investors now worry about the impact to the industry from the stricken Italian cruise liner. RCL sees higher options volume today as well. (Looks like the original spread was bought on 11/14 for about $1.23. It was a 1X2.
