market folly

John Thaler's hedge fund JAT Capital just filed a 13G with the SEC regarding shares of IMAX Corp (IMAX). Per portfolio activity on August 22nd, JAT has disclosed a 4.6% ownership stake in IMAX with 2,979,280 shares.

Since the end of the second quarter in June, this marks a 349% increase in their position size as they've gobbled up shares. Since the end of June, shares of IMAX are down 48%.

Some managers have had somewhat of a '3D' pairs trade on by going long IMAX and short RealD (RLD), but we obviously can't see JAT's shorts.

Thaler's Background

Before he founded JAT, Thaler worked at Shumway Capital Partners (which returned capital this year). Chris Shumway himself invested in JAT's launch. Thaler covered technology, media and telecom and managed the internal Omni fund while at Shumway. Before that, he worked at Spectrum Equity Investors in private equity.

Due to his background, you'll see an emphasis on the TMT sectors in his portfolio. Thaler earned his BA in Economics from the University of Chicago. In 2008, JAT returned -5.9% and in 2009 returned 23.2% gross. This isn't the first time we've covered Thaler's fund as we've also detailed JAT's bet on social media via SINA.

Per Google Finance, IMAX is "is an entertainment technology companies, specializing in motion picture technologies and presentations. The Company’s principal business is the design and manufacture of digital theater systems (IMAX theater systems) and the sale or lease of IMAX theater systems."
