Every quarter, many money managers have to disclose what they've bought and sold, through 13-F filings. Their latest moves can shine a bright light on smart stock picks.
Today let's look at Tudor Investment, founded in 1980 by Paul Tudor Jones and featuring the flagship Tudor BVI fund. Jones, featured in Jack Schwager's Market Wizards: Interviews With Top Traders, was one of the few to foresee the 1987 market crash (and he made many millions on it as well). Known for focusing on short-term trading, equity, venture capital, debt, currency, and commodity markets, he has recently been employing a more conservative strategy, resulting in some performances that have been less spectacular than usual.
The company's reportable stock portfolio totaled $2.9 billion in value as of March 31.
So what does Tudor's latest quarterly 13-F filing tell us? Following are a few interesting details.
New holdings include Seadrill
Among holdings in which Tudor increased its stake were Frontier Communications
Entropic, focusing on semiconductor technology for the home entertainment niche, has bought the set-top business of bankrupt Trident Microsystems and is working with Intel to get into the Internet-TV business as well. Bulls like its double-digit revenue growth and its balance sheet, while bears fret over its volatility, falling margins, and potential overdependence on a few customers.
Tudor reduced its stake in lots of companies, including wireless broadband provider Clearwire
Finally, Tudor unloaded plenty of companies, such as Sirius XM Radio
We should never blindly copy any investor's moves, no matter how talented the investor. But it can be useful to keep an eye on what smart folks are doing, and 13-F forms can be great places to find intriguing candidates for our portfolios.
