The stock has gotten beaten up pretty badly. And it seems a large portion of that is due to fear about the Discover and Brex acquisitions being too much to handle at once. But I can't find any news stories about those acquisitions having negative effects yet. And as long as sub prime and near prime consumers don't get crushed in the short term they'll have time to finish the integrations and become a somewhat more diversified company.
Tempted to buy soon but waiting for price to fall more.
