About Josh Tarasoff

Josh Tarasoff runs Greenlea Lane Capital, a concentrated long-only equity fund with a philosophical bent unusual even by value-investing standards — he publishes extended essays on decision-making, business quality, and what he calls "productive uncertainty" that read more like epistemology than pitch decks. The portfolio reflects that disposition: nine positions as of 2026 Q1, with roughly 72% in the top five, anchored by canonical compounders (AMZN, BN, BRK/A, MKL) and a meaningful cash-equivalent sleeve in SGOV. The SGOV position is worth flagging for 13F readers — it signals either tactical caution or dry powder, not a thesis. The book is straightforward long equity with no known systematic use of shorts or derivatives, so the filing is a reasonably faithful representation of the portfolio. The clone backtest shows negligible excess return versus SPY over seven-plus years, which is the honest context for any follow-on analysis; whether that gap closes depends entirely on holding-period alignment with Tarasoff's own, which tends to be long.

2026Q2 brief

Josh Tarasoff's Greenlea Lane Capital managed a tightly wound 10-position, $360M portfolio in 2026Q2, adding just one new name: SPOT (Spotify) at 5.0%, which slots in as the seventh-largest holding. The initiation fits Tarasoff's pattern of owning dominant platform businesses with durable network effects — AMZN (18.3%), BN (16.3%), GOOGL (9.8%), and NFLX (5.4%) all share that DNA, and Spotify's improving margin profile and podcast/audiobook optionality arguably justify placement alongside them. The 10.6% slug in SGOV (short-term Treasuries) is notable — it's essentially a cash proxy suggesting either dry powder discipline or portfolio ballast while awaiting better entry points. No trims, no exits, and no adds to existing positions signal very high conviction in the current book. The continued holdco concentration in BN (16.3%) and BRK/A (13.0%) reflects a preference for compounding vehicles run by elite capital allocators. The one thing to watch next quarter: whether TSLA (5.5%) is trimmed — it's the position that looks most stylistically inconsistent with the rest of the book.
