Renaissance Technologies may have netted over $1.5 billion in two months, as it bought a load of Tesla stock before it rocketed up 91% this year.
The quantitative hedge fund, founded by Cold War codebreaker and math professor Jim Simons, bought 3.3 million shares in Elon Musk's electric-car startup last quarter, recent SEC filings show. The purchases boosted its total holding to about 3.9 million shares - a 2.1% stake - at the end of December, according to Bloomberg data.
Renaissance's Tesla shares were worth about $1.6 billion then, based on Tesla's $418 stock price at the time. Given Tesla's shares now change hands at $800, the fund's stake is now worth almost $3.2 billion.
That return would be remarkable enough, but Simons may have raked in closer to $3 billion if he bought into Tesla at the $250 mark in early October, then sold at the $970 peak earlier this month. At those price points, Renaissance's stake would have surged in value from less than $1 billion to almost $3.8 billion.
Tesla stock skyrocketed after the automaker posted strong earnings, opened its Shanghai factory in record time, and announced a production target of 500,000 vehicles this year. The rally has boosted Tesla's market capitalization to over $140 billion, surpassing the combined market caps of Ford, GM, and Chrysler, the "big three" US automakers.
The stunning stock rally has burned short-sellers and spurred investors, industry veterans, and even politicians to warn it won't last.
