BOSTON, Jan 26 (Reuters) - Sitting on a double-digit loss
that is the deepest in his firm's history, billionaire investor
Bill Ackman on Tuesday told investors that he made mistakes last
year in not cutting two big positions but said he sees plenty of
new investment opportunities.
Ackman, whose Pershing Square (N:SQ) Capital Management lost
between 16 percent and 20 percent in its funds in 2015, said it
was a "very costly" mistake that he did not sell drug maker
Valeant Pharmaceuticals International Inc (N:VRX) VRX.TO when the
stock price rose to $200 over the summer.
