The problem with c level executive resigning

$MongoDB (MDB.US)$ when you get ppl resign and there is no immediate replacement, usually that leads to believe that there is friction internally. If mdb would have said we are replacing cfo stock would have gone up 20%. But friction can be many things, it can be the cfo was banging the secretary or cooking books. Either way this cloud will pass and stock will go up again, it might be as early as tomorrow where we can see 7-8% rise
