Good grief, one day of recovery and suddenly happy days are here again for the bulls?! If I were long, I'd be just a wee bit concerned about how anxious (desperate?) some folks are to call the bottom. I think considerably more fear and worry will be necessary to register an intermediate term low.
In addition, after a four plus year bull run it's also possible the tide has turned on a longer term basis. If the longer term trend has turned down, buying the dips will become quite painful. Bear markets can remain oversold for long periods just as bull markets can remain overbought for long periods.
