Jive Software (JIVE -19.3%) tumbles after providing soft guidance to go with in-line Q2 EPS. The enterprise social networking software firm forecasts Q3 revenue of $28M-$29M and EPS of -$0.10 to -$0.12, largely below a consensus of $29.3M and -$0.10. 2012 guidance ranges are in-line, but the mid-points are below consensus. Citi has downgraded Jive to Neutral in response. Shares had rallied in June due to Microsoft's purchase of rival Yammer, but are now close to their post-IPO lows.
