Hedge funds apparently like the sound of an auction house gavel even more than previously suspected.

Another major hedge fund has taken a big stake in auction house Sotheby’s. Atticus Capital has built up a 5.4% stake in the company, according to regulatory filings. At the end of March, the New York-based hedge fund owned no substantial Sotheby’s holding.

Atticus’ move follows a similar one by SAC Capital Advisors, which took a 5.9% stake in Sotheby’s to become the company’s third-largest shareholder. News of SAC’s stake was quickly followed by an exhibit of SAC founder Steven Cohen’s art collection at Sotheby’s New York headquarters in April.
