## Questions

### Who runs investment decisions at JAT Capital?

John Thaler serves as the sole founder, Portfolio Manager, and the principal whose capital the firm now manages. Since returning all external investor capital in 2015, Thaler has been the firm's exclusive client, making all material portfolio decisions. He does not manage capital for other families or institutions.

### Is JAT Capital still a hedge fund accepting outside investors?

No. JAT Capital Management returned all outside investor capital in July 2015 and converted to a private investment office. The firm has not accepted external institutional or individual investor capital since that date. It continues to file regulatory disclosures that reflect ongoing investment activity for John Thaler's personal accounts.

### What is JAT Capital's relationship to the Tiger Cub network?

JAT Capital is a direct descendent of the Tiger Cub lineage. John Thaler worked as a partner and senior analyst at Shumway Capital Partners, founded by Chris Shumway, who himself previously worked at Tiger Management under Julian Robertson. The firm's long/short equity approach with concentrated TMT bets reflects this heritage.

### What asset classes and sectors did JAT Capital focus on when it managed institutional capital?

The firm ran a concentrated, global long/short equity strategy focused primarily on technology, media, telecommunications, and consumer discretionary sectors. Public filings indicated heavy weightings in large-cap internet and technology companies. The fund also employed short positions and macro hedges, though the primary alpha generation came from stock-picking in growth equities.

### How large was JAT Capital at its peak?

JAT Capital's assets under management peaked at more than $3 billion in 2013, per public and industry records. By the time Thaler returned capital in mid-2015, the firm had roughly $1.7 billion in regulatory assets under management. The firm's current AUM is not publicly disclosed and reflects only Thaler's personal wealth, which Altss estimates in a broad $1–5 billion band.
