Steve Cohen's giant New York City penthouse is back on the market for a fourth time, but now it costs $72 million

The mansion in the sky is now up for grabs for $72 million - down $7 million from its listing price last summer. He first put it on the market in 2013, when it was offered for $115 million. He later listed it for $98 million, then again for $79 million.

Cohen, who runs Point72 Asset Management (formerly known as SAC Capital), picked up the apartment for $24 million in 2005. He hired the late architect Charles Gwathmey to redesign the 9,000-square-foot space, which has five bedrooms and six baths. Located at One Beacon Court - part of the Bloomberg Tower complex - it's in a prime location on the southeast corner of Central Park.

It's now listed with Richard Steinberg and Matthew Slosar of Douglas Elliman.
