I think she misunderstood the financials. JPM didn't "miss" analysts' expectations - it exceeded them - and probably in large part due to the continued benefits from its acquisition of WMB.
The reason it "tanked" is because JPM did not pay out a dividend - which indicated to many analysts that JPM expects to see more losses from mortgage loan defaults in the future. Anyone with knowledge on JPM's exposure these days - particularly to WMI as a result of its acquisition of WMB for a mere $1.88B - knows that JPM is holding on to all of its cash because a settlement is going to cost quite a bit.
