Mala Gaonkar, co-portfolio manager at Lone Pine Capital LLC:
Gaonkar's pick was doing quite well until it reported earnings last week. Microsoft Corp. ended up tumbling about seven percent after reporting quarterly results and took her winnings down to four percent.
Jeffrey Gundlach:
Gundlach had a slightly less conventional idea: buy Puerto Rican bonds. Attendees weren't too surprised by his pick given that Bloomberg reported his fund's stake in junk-rated Puerto Rican debt just a couple of weeks before his speech. His pick hasn't done as bad as you might expect given the turmoil that has continued to plague the region since his call. The S&P Municipal Bond Puerto Rico Index is down about five percent.
Bill Ackman of Pershing Square Capital Management LP:
One of Ackman's picks is performing quite well, but the other has been grabbing headlines for all of the wrong reasons. Jarden Corp. is up 15 percent since last May, but his bullish bet on Valeant Pharmaceuticals International Inc. has been demolished. The stock is now down 84 percent.
Perhaps this year will look a bit better.
