Express Scripts Inc (ESRX) $44.86 +6.30%

ExpressScript shares are up $2.80 to $45 following a positive earnings report and option volume is 3x the daily average with 9,500 calls and 6,200 puts traded thus far. Volume leaders are the August $47.50 calls and $42.50 puts, but the largest trade is in the November 40 puts as a 1,000 contract block traded. Today’s price action could be exaggerated by short covering as shares of ESRX and rival MHS have been hit hard in the past two weeks. ESRX actually traded down to $38 in the aftermarket following yesterday afternoon’s earnings release.
