Friday's a good day for reading some soft news - like Fortune magazine's “40 Under 40″ ranking of business’s hottest rising stars.  Yes, it's got all the techies - the Mark Zuckerbergs, and the Sergei Brins - who form the bulk of the list.  Representing finance, there are hedgies who have amassed a fortune clipping those lucrative incentive fees from their billion-dollar funds. 

John Arnold, 36, who runs Centaurus Advisors, is a Houston-based energy trader who was #9 - he's had a successful second act after leaving Enron.  Further down, is Greg Jensen, 36, of Bridgewater Associates, the No. 2 to Ray Dalio at one of the world’s largest hedge funds.  Boaz Weinstein, a Deutsche Bk star derivatives trader (and chess master), rebounded to 17 - after having lost a lot for DB, he formed the $1.5 billion Saba hedge fund.

From private-equity, there's Adam Palmer, 37, at the Carlyle Group - he's #35.  Mr. Palmer is basically a Carlyle lifer, having joined the firm in 1996 and focusing on its original stock in trade - aerospace and defense investments.  He made partner at age 32 and has the 18th longest tenure at the firm out of 900 people, and could help lead the private-equity giant some day.

Other finance types:  Aryeh Bourkoff, 37, a media banker at UBS.  Eric Edidin, 38, is the founder of Archer Capital Mgmt, after his stint in Blackstone Group’s restructuring group.
