Over the past year, based on his increasingly more dour media appearances, billionaire Carl Icahn had been getting progressively more bearish. At first, he was mostly pessimistic about junk bonds, saying last May that “what’s even more dangerous than the actual stock market is the high yield market.” As the year has progressed his pessimism has become more acute and in December he said that the “meltdown in high yield is just beginning.” It culminated in February when he said on CNBC that a “day of reckoning is coming.”

Some skeptics thought that Icahn was simply trying to scare investors into selling so he could load up on risk assets at cheaper prices, however that line of thought was quickly squashed two weeks ago when Icahn announced to the shock of ever Apple (AAPL) fanboy that several years after his “no brainer” investment in AAPL, Icahn had officially liquidated his entire stake.

As it turns out, Icahn’s AAPL liquidation was just the appetizer of how truly bearish the legendary investor has become.

As readers will recall, when it comes to what we believe is one of the world’s most bearish hedge funds, we traditionally highlight the net exposure of Horseman Global, which not only has been profitable for the past four years, it has done so while running a net short book. To the point, as of March 31,Horseman was net short by a record 98%.

As it turns out this was nothing compare to Icahn’s latest net exposure.

In the just disclosed 10-Q of Icahn’s investment vehicle, Icahn Enterprises LP in which the 80 year old holds a 90% stake, we find that as of March 31, Carl Icahn – who subsequently divested his entire long AAPL exposure – has been truly putting money, on the short side, where his mouth was in the past quarter. So much so that what on December 31, 2015 was a modest 25% net short, has since exploded into a gargantuan, and unprecedented for Icahn, 149% net short position.
