Founding Kase Capital Management

In 1999, Tilson founded Kase Capital Management, a value-oriented hedge fund based in New York. The firm launched at the height of the dot-com bubble, a period defined by speculative excess and market volatility.

Kase Capital distinguished itself by avoiding unprofitable technology stocks and focusing instead on undervalued companies with strong balance sheets. This contrarian stance paid off in the early 2000s, as Tilson’s funds avoided the worst losses of the market crash.

• Fundamental equity analysis

Closure of the Hedge Fund

By the mid-2010s, changing market dynamics posed challenges for traditional value strategies. After several years of underperformance, Tilson made the decision to wind down Kase Capital in 2017.
