Legendary investor

Warren Buffett's

Berkshire Hathaway

added Bank of New York Mellon to its portfolio in the third quarter, a stock that has generated buzz as

a likely acquisition target for larger banks.

Notably, Berkshire appears to have sold more shares than it bought in the third quarter. Reports suggest that many of those holdings were picks of Lou Simpson, Berkshire's other investment manager, who will retire this year. There has also been speculation that Berkshire is raising money for a big buy, so investors will have their eyes peeled.

In October,

Buffett announced the appointment of Todd Combs, a little-known hedge fund manager, to help run a significant portion of the investment portfolio at Berkshire Hathaway. Combs has been heading

Castle Point Equity

, a Greenwich, Conn.-based hedge fund with total assets under management of about $280 million, much smaller than Berkshire's nearly $50 billion portfolio.

Ever since he called gold the "ultimate bubble" earlier this year, investors have been waiting for Soros to burst it for them by selling out his large stake in the largest gold exchange traded fund

SPDR Gold Trust

(GLD) - Get Report

.

While Soros Fund Management has been paring exposure to SPDR Gold, it has added rival gold ETF

iShares Gold Trust

(IAU) - Get Report

to its holdings. Clearly

Soros still likes gold.

Of course, it is worth noting that the billionaire investor claims he is not actively involved in running Soros Fund Management, so it is possible that his fund's holdings do not really reflect his own views.

stepped up exposure to healthcare and solar stocks in the third quarter. Dendreon was its most notable addition.

John Paulson's

Paulson & Co has had a testing time in 2010, which has proved to be a rough one for the hedge fund industry.

The hedge fund titan became famous for his $15 billion bet against sub-prime mortgages in 2007. In 2008, he made money shorting bank stocks and in 2009, he switched sides, making large bets on the nation's big banks, scooping them up at low valuations.

The relative underperformance of big banks through much of 2010 had reportedly weakened his fund's returns. But the gold and equities rally in September and October helped bring his fund

back into the black. Advantage Plus, his flagship fund, rose 2.55% in October and is up 2.54% for the year, according to a

Reuters

report. The fund's gold-denominated share class was up 4.7%.

Paulson moved to cut back his exposure to big bank stocks during the third quarter. He exited

Goldman Sachs

(GS) - Get Report

First Horizon

When

Carl Icahn

buys a significant stake in a company, you know big change is around the corner. The activist investor is legendary for his role in staging outright takeovers, waging proxy wars to replace management and calling for corporate restructuring to create value.

Icahn is waging an ongoing battle against

Blackstone's

(BLK) - Get Report

bid for energy company

Dynegy

(DYN)

, arguing that the $4.50 a share offer price undervalued the target. Blackstone raised its offer price to $5 per share, ahead of a crucial shareholder vote on the deal on November 17. The vote was then delayed to Nov. 23, to give shareholders more time to evaluate the deal. Ultimately, Dynegy failed to garner enough support for the Blackstone takeover and scrapped the bid. It is now evaluating other options.

Stockpickr Tools Carl Icahn's Portfolio

Icahn holds a less than 12% stake in studio

Lionsgate

(LGF)

and has been

attempting to acquire the studio. Icahn also owns debt in

Metro-Goldwyn Mayer

and initially supported a bid by Lionsgate to take over the beleaguered studio, but in the end backed a bid by rival

Spy Glass Entertainment

.

Lionsgate sued Icahn alleging that he interfered with Lions Gate's efforts to merge with MGM until he was able to obtain a large portion of MGM's debt and thus profit from a combination, the

Associated Press

said.

Irrespective of his success, Icahn sure knows how to up the ante in a takeover battle.

David Tepper set markets on fire in September, sparking what came to be known as the "Tepper rally",

when he said that stocks had no way to go but up as the Federal Reserve would without a doubt launch another round of quantitative easing.

His bet on the central bank's move certainly paid off. According to the

New York Times'

DealBook, Appaloosa Investment, his flagship fund, gained 5% in October and is up 21% year to date, a period that has seen over 400 hedge funds close shop.

It would be interesting to see if Tepper's picks in tech, especially Cisco after it crashed 16% two weeks ago following a weaker than expected guidance, will pay off.
