In trading today, Foundation Medicine $FMI stock has completed a remarkable roundtrip, giving up all the gains from a spectacular move from sub-$20 to over $50 on the back of their splashy deal with Roche announced at the JP Morgan Healthcare Conference. While the stock has been dribbling downward for months, the last ten bucks comes as a result of their second quarter earnings release and conference call held on July 29, 2015 where the company slashed its 2015 guidance for FoundationOne test numbers and revenue.
