Soros seems to like his cheap business technology stocks, adding 1 million shares to a position in Extreme Networks ( EXTR), a network infrastructure company, which trades at under $3 a share. The hedge fund's total interest in the company rose to 8 million shares. Soros and Paulson are both famous for playing energy stocks and commodities from oil to gold. Both managers, for instance, continue to invest heavily in the yellow metal. In energy, Paulson made a notable portfolio addition of 3 million shares of XTO Energy, and took an initial 3 million-share stake in Devon Energy ( DVN). Soros, though, made a true energy dollar-store bet in the first quarter, buying more than 1 million shares of independent oil and gas explorer Cano Petroleum ( CFW), which traded at a share price below $1 at several points during the first period. Cano shares closed at $1.13 on Tuesday. -Reported by Eric Rosenbaum in New York.
