I know this sounds elementary, but doesn't GILD's P/E ratio drop from 13 to 10 tomorrow? There may be a data lag, but the information will begin showing up in metrics. Also, the forward P/E of 9 may go even lower.
Of course we should also expect upgrades from the analyst community because of the increased guidance. Don't get too excited. Have a glass of wine. Take an Ambien and check back early tomorrow morning.
