Goldman, JP Morgan are likely to be the most active as dealmaking returns to Wall Street: KBW

At some point in the not too distant future, the math won't make sense anymore for banks to keep blowing cash into buying back their own shares. When that happens, a climate for deals finally could develop. In that case, JP Morgan and Goldman Sachs both could emerge as significant M&A players, broadening their reach not directly into banking but rather ancillary industries that will help the Wall Street institutions grow, according to an analysis Monday by Keeefe, Bruyette & Woods.
