Today I bought more Amgen (AMGN). It has a low P/E ratio, pays a dividend, and has a pipeline I like. On the other hand, it is a big company, so it can't grow as fast as say, Regeneron (REGN) or even Alexion (ALXN), both of which looked mighty tempting today.
Next week AMD reports Q1 results on Thursday. The following week I have at least 5 biotech stocks reporting Q1 results. Maybe stocks will get cheaper, but my guess is with the economy reviving nicely and actual earnings coming in, buyers will be back soon enough.
