About Henry Ellenbogen

Henry Ellenbogen, the star manager of T. Rowe Price's New Horizons fund, founded Durable Capital to run his small- and mid-cap growth playbook across public and private markets — backing 'durable growth' companies before they become obvious.

Durable's 13F is a curated growth-discovery list: software, tech-enabled services, and consumer names in the sweet spot between venture scale and mega-cap fame.

Methodology: turnover is min(value bought, value sold) ÷ average reported value across the two quarters — value-based, so market moves inflate it slightly versus a share-based measure. Concentration and largest position are shares of the filing’s total reported value, options excluded. New/exited counts compare against the prior filed quarter. All figures derive solely from the fund’s 13F filings.
