Just a few of days ago, fellow Fool Sean Williams (TMFUltraLong) agreed with yours truly and questioned Regeneron's lofty valuation:

[F]antasyland valuation. There's no way that Eylea's forecast of $250 million-$300 million in sales translates into a $10.5 billion market cap. Avastin should give Eylea enough competition to bring Regeneron back to Earth. Never get too excited about new drugs otherwise you often get burned.
