Monarch Casino (MCRI, news, chart, volatility) is seeing action. The casino-operator was the subject of increased call buying in mid-December when the Jan calls at the $10 strike saw multiple days of active trading and increasing open interest. Now, it appears a large position in those calls (12,735 contracts) is being closed out and rolled to the March 10/12.5 call spread (along with 5,000 March 10 puts).
