Revisiting the big banks

On November 7th a post here suggested buying an equal weighted basket of the big banks(Citicorp, Bank of America, JPMorgan Chase, US Bancorp and Wells Fargo). It suggested further that this basket would lead to an aggregate 15% gain in six months or "much higher". The post gave six reasons why this performance could be expected.

Three months later Citicorp is up 15%, BofA 24%, JPM 18%, Wells 26%, and USB 16%. That's a 20% gain for the basket. So far so good.
