If you look beyond the headlines with the new 13F filings, there are some interesting moves from some big-time investors not named Warren Buffett.
The first one to jump off the page: Steven Cohen's SAC Capital basically doubled down on Apple. The firm's holding jumped 553,000 shares to 876,000.
On Wall Street, the debate on names that have risen so much—80 percent in the last year for Apple—is whether an investor will get burned if buying at these levels. SAC certainly seems to think there's room to run with Apple .
The Bill and Melinda Gates Foundation is better known for its philanthropy than for its investment prowess, but it likely realized a decent gain from its stake in Goldman Sachs. It liquidated all 500,000 shares.
One other company that's worth noting: . David Einhorn's Greenlight Capital bought more than 55 million shares worth about $254 million. Sprint's stock is up more than 40 percent in the last year and the company recently announced subscriber growth for the first time in three years.
Back to Buffett for a moment. What makes investors like Warren Buffett great is not just when they buy, but when they sell. Take Nalco, the chemical company based in Illinois.
If you marginally know the name, it probably stems from the coverage of the Gulf oil spill. Nalco's chemical dispersant was widely used by BP as it frantically tried to deal with the problem.
Berkshire Hathaway sold all of its 6 million shares in the last quarter. Reportedly, it bought that stock more than two years ago at an average price that was less than half of what it traded for at the end of 2010.
That's approximately a $100 million profit of a roughly $80 million investment.
