Freeport McMoran (FCX) is up 73 cents to $34.90 and 83,000 calls traded, compared to 27,000 puts. The top trades of the day are in the May 35 and 40 calls after a strategist apparently bought the spread 24000X for $2.15 on the NYSE. One of the legs might be closing and it could possibly be a roll from the lower to the higher strike.
