Citadel Investment Group founder Ken Griffin does not take the non-compete agreements he makes employees sign lightly. In a crowded field, perhaps no one this side of Alan Howard takes them quite as seriously.

Daniel Nehren knows this. He worked for Griffin for two whole years—an eternity by Citadel standards—before departing, eventually for Barclays, in May of last year. We say eventually because, of course, Nehren had an eight-month non-compete to wait out, and in case K.G. was thinking of making his former equity execution head the next Misha Malyshev, Nehren’s decided to be as conspicuous in his non-competition as possible. We’re sure there are many, many pictures on his Instagram of him in all sorts of exotic locations with want of good wifi. When he’s not not working abroad, he’s been sitting in the Park Avenue median between 55th and 56th streets so that Griffin’s non-compete enforcers can keep an eye on him not competing. And then there’s this:


Call off your goons, Ken! Nehren is finally free to ply his trade elsewhere.
