Overextended?

Well some areas are up a lot in the last couple sessions so I am looking at my favorite scalps, GOOG and BIDU on a reaction pullback. I.E. panic down and buy for a scalp bounce. Also, ENER might bounce after it looks to open lower from their earnings release last night. CERN might be a buy being an uprade to a 100 price target. Electronic medical records are the future. More so after the many records lost from Katrina's wake. Thus. here is a need for off-site backup and I feel this disaster hit home again for that to be mandated. Outside of that, who knows. The market is short-term over bought but, still it seems the best trades are the news plays, volume breakouts.
