Royal Caribbean's ( RCL) stock is rising along with heavy options trading ahead of its earnings report Thursday.

The average volume for the cruise line operator is about 2,700 options, but more than 22,800 contracts changed hands Friday, according to OptionMonster's tracking system. The bulk of the action centered on the June 15 calls, in which more than 4,100 calls traded versus open interest of just 577 contracts.

The stock ended Friday's regular session up 6.2% to $11.98 and then made an even $12 in after-hours trading. The shares have been in a fairly steady uptrend since closing at their 52-week low of $5.40 on March 3, but the stock is still only about one-third of its $35.35 high.
