Express Scripts (NASDAQ:ESRX) plunges 12.6% following its Q3 report late yesterday, when it said analysts' 2013 forecasts are "overly aggressive." ESRX said EPS would grow but didn't provide specifics, while the Street expects $4.50/share. A "weak business climate and the unemployment outlook" may lead to a loss of members, depressed drug utilization and "increased client demands and expectations," Express Scripts said.
