Legendary investor Carl Icahn recently added a "sizable position" of Apple to his $16 billion holding company -- Icahn Enterprises.

Since he announced his purchase on Sept. 11, 2013, Apple is up about 20%.

After making the purchase, Icahn was quoted saying it was a "no-brainer" investment, citing that the company's valuation was "extremely cheap" by the numbers.

Icahn should know, too. Unlike most of today's billionaires, he made his fortune entirely by investing in the stock market. Since he founded Icahn Enterprises less than 30 years ago, his company has enjoyed total returns in excess of 288,000%.

To put that in perspective, if you had invested $1,500 with him back in 1987, the size of your position would be worth over $4.3 million today
That kind of performance is one reason Chartered Market Technician Michael J. Carr recently designed a trading system to leverage the financial genius of investing gurus, like Icahn.

By applying his proprietary trading system to stocks that are held by the market's 20 most successful gurus -- including Warren Buffett, George Soros and David Einhorn -- Michael has earned big gains betting alongside the world's most renowned investors.

For example, on Sept. 12, Michael's system identified a buy on Netflix (NASDAQ: NFLX), one of Carl Icahn's top portfolio holdings. Just three months after his system gave the signal, Netflix is up over 20%.
