Davos always attracts a cluster of global bankers, but the list of those braving the Swiss weather this year includes a particularly large contingent of Wall Street financial titans.

Participants include not just Jamie Dimon, head of JP Morgan, Lloyd Blankfein, head of Goldman Sachs, and Richard Fuld, head of Lehman Brothers, but also a large contingent of private equity leaders. These include Stephen Schwarzman of Blackstone Group, David Rubenstein of Carlyle Group.
