Mosaic Earnings Play

Sold the Mosaic (MOS) 67.5/65.0 put spread for $0.23 just before the close last night (1/4/11). MOS was set to report earnings after the close. It seemed and earnings beat was definitely in the cards given all the upbeat news around the fertilizer industry and commodity space in recent moths. Given the earning beat and subsequent price rise I am confident the options will expire out of the money for a nice quick 10% gain (not counting commissions). I would close the position but I put such a small amount into it that the commissions make it more viable to just wait for expiration.
