(Bloomberg) -- Stock-picking hedge funds led by Chase Coleman, Philippe Laffont and Andreas Halversen notched double-digit gains in the first half, beating turbulent equity markets amid the coronavirus pandemic.

Tiger Global Management, run by founder Coleman, has climbed roughly 17% this year in its flagship hedge fund, according to people with knowledge of the matter. It was up about 6.5% in June, said the people, asking not to be named because the information is private. Meanwhile, Halvorsen’s Viking Global Investors rose 2% in its hedge fund in June, bringing this year’s returns to 11%, according to another person.

Laffont’s technology-focused Coatue Management surged 8.6% last month through June 26, extending gains for the year to 19%, a separate person said. That outpaced the gains of the Nasdaq 100 Index, which rose 16% in the first six months.

After falling 20% in the first quarter, stocks soared 20% in the second quarter, the most since 1998, as the Federal Reserve offered unprecedented market support. But while U.S. consumer confidence rose in June by more than forecast, hopes of a quick economic recovery have been shaken by the increase in Covid-19 cases across the nation.

The managers share a common background. They are all so-called Tiger Cubs, the term for alumni of legendary stock-picker Julian Robertson’s Tiger Management who went on to start their own hedge firms. Other members of the group, which tend to trade in similar ways often with a focus on technology stocks, include Lee Ainslie and Stephen Mandel.

Representatives for the firms declined to comment.
