Plenty of investors follow big money because, after all, those guys got rich for a reason, right? The brand new iBillionaires Index launched on Wednesday, giving investors a means to “track and measure the performance of Wall Street’s biggest winners: financial billionaires.”  The index uses 13F filings that disclose holdings of the 30 large-cap equities listed on the S&P 500 to follow the performance of top market players, including Warren Buffett, Carl Icahn, Daniel Loeb, John Paulson, Wilbur Ross, David Tepper, David Einhorn and more.  Investors that manage over $100 million are required by the Securities and Exchange Commission to disclose their holdings within 45 days after the end of a quarter.  The deadline for Q3 was Thursday and the reason that so much buzz is going around today.

If you’re wondering about some of the recent moves that have been on the wires today, here are a few for you (remember these filings can come months after the purchase and this certainly is only a sampling):

John Paulson:  Kept his 10.2 million shares of the SPDR Gold Trust, added ADR shares of Anglogold Ashanti (AU) to now have 31.4 million, bought 646,800 shares of FedEx (FDX) , snapped up some Time Warner Cable (TWX) and added to his stakes in and Family Dollar Stores (FDO) , Vodafone Group (VOD) and Aetna (AET) .  Paulson, the founder of Paulson & Co., cut his exposure to Sprint Corp. (S) , Realogy Holdings Corp. (RLGY) and MGM Resorts International (MGM) .

George Soros and Daniel Loeb have also jumped on the FedEx bandwagon with Paulson.

Daniel Loeb:  In addition to his new FedEx holdings, the outspoken billionaire and head of Third Point LLC, has big stakes in Activision Blizzard (ATVI) , Nokia Corp. (NOK) and International Paper Company (IP) .  Loeb tripled his holdings in Gilead Sciences Inc. (GILD) to 500,000 shares and opened a new position by purchasing 100,000 shares of Google (GOOG) .  He also thinned his position in Yahoo (YHOO) from 62 million shares to 16 million.

George Soros:  Opened a position in Microsoft (MSFT) with 12.6 million shares and 126,500 call options and trimmed his stake in Google from nearly 400,000 to 164,500 and cashed out on its 11,200 Google call options.  Soros, who runs Soros Fund Management, took some lumps this week with his 800,000 share position in Millennial Media, Inc. (MM) , 237,000 shares of Cisco Systems (CSCO) and Lumos Networks (LMOS) , although it’s notable that he is still in the green on both Cisco and Lumos.   Soros also increased his position in Mercury Systems (MRCY) to 1.7 million shares in October, a company he has been trading for more than five years.

Carl Icahn:  Raised his holdings in Navistar International ($NAV) by 13 percent to 13.3 million shares.  He bought a few more shares of Apple (AAPL) to now have 4.73 million shares and kept his stake in Transocean (RIG) at about 21.5 million shares.  Icahn shed most of his Netflix (NFLX) stock during the third quarter and in October (for a profit of a whopping $800 million).  As such, Icahn Enterprises LP (IEP) has about 2.6 million shares of Netflix still in its portfolio.

Warren Buffett:  Grew Berkshire Hathaway’s ($BRK.A) position in Exxon Mobil (XOM) to 40 million shares while dumping 10.5 million shares of Conoco Phillips (COP) , leaving Berkshire still holding 13.5 million shares.

David Einhorn:  Sold off his position in Capital Bank Financial Corp. (CBF) and opened positions in Intrexon Corp. (XON) and Tempur Sealy International (TPX) .  Einhorn runs Greenlight Capital, Inc.
