Carl Icahn's Netflix investment may be the most annoying Best Trade Ever.
Last fall, Icahn revealed that he had bought a 10 percent stake in Netflix. His average price per share was around $58 each.
Back on Oct. 10, Icahn started selling shares. The biggest sale took place Tuesday, when he sold for an average price of just over $344, for a total of $819 million. That means he made a profit of about $645 million on Tuesday's sale alone.
