You better read rule 10b5-1 in the discloser make in the 2011 annual report. Note the section on ESRX and Walgreens ability to offset losses over 75% of revenue, Walgreens it is estimated is at 85% of non retention, with, no estimation should Esrx/Medco merger be approved.
Something will happen, as we are in March and beware the Ides of March should be noted!!
