Jim Simons, chairman and CEO of Renaissance Technologies Corporation, does not give many interviews. As he once put it, citing Benjamin the Donkey in Animal Farm: "God gave me a tail to keep off the flies. But I'd rather have had no tail and no flies".

Then we find him appearing in a least expected program:



As a trader, the billionaire hires PhD’s who came over from overseas to implement his trading strategies. As a citizen of the US, he is advocating improving the quality of education in mathematics and science in this country. He donated generously to courses related to math and science educations.

GuruFocus tracks his portfolio. As of September 30, 2010, just on the long positions, he held 2772 stocks, of which 805 of them are new stocks. Total value of his stock was over $24 billion. Click on Jim Simons for details.
