Holocene Advisors Portfolio holdings
Holocene Advisors manages private funds, including a global long/short stock fund and a concentrated long-only fund. Its founder and chief investment officer, J. Brandon Haley, started the firm in 2016. The long/short fund holds both long and short positions so that it is not exposed to overall market moves, while the long-only fund, called the Holocene Children's Fund, holds a concentrated portfolio for the long term. Stock ideas come from research by teams that each focus on one sector. The name comes from the Holocene Epoch, the geological era that began about 11,500 years ago.
