CAPS member gamblingkev elaborates on the bargain opportunity:

[Santander] does not share in most of the problems in the Spanish banking market but they do get hit every time talk of default in Greece or Portugal is mentioned. They have great prospects for growth in South America and I think they're undervalued based on that. They also pay a very solid dividend.
