William Ackman, founder and CEO of hedge fund Pershing Square Capital Management, speaks at the Sohn Investment Conference in New York, May 5, 2014. Activist investor Ackman said on Monday that he recommends the shares of mortgage finance giants Fannie Mae and Freddie Mac because the companies have low liquidity risk.
Appearing on "Halftime Report" with Scott Wapner, Ackman previewed a presentation on the firm he's giving tomorrow that he says is the most important of his career.
