market folly

Per CNBC, Bill Ackman's Pershing Square has reportedly been building a stake in United Technologies (UTX).  Ackman told Scott Wapner that he thought the company was "great."  The company has been awaiting the closure of its acquisition of Rockwell Collins (COL).  Additionally, UTX management has said they've been evaluating splitting up into a few different entities.

Secondly, Ackman has exited his bet against Herbalife (HLF).  He had previously been outright short shares, but then this past November restructured the short via put options.  Now, he's out of his short bet entirely.  

This comes after he said back in 2013 that he'd go to the "ends of the earth" to shut the company down, dubbing it a pyramid scheme.  Shares of HLF are already up 36% year-to-date after being up a similar amount already last year.

Pershing Square has been active lately, as it also recently revealed a new Nike (NKE) position.
