Renaissance Capital LLC holds a focused book of 52 reported positions worth $181.3M as of Q2 2026 (disclosed Aug 5, 2026, a ~36-day 13F lag). This quarter Cerebras Systems Inc - A first appears in 13F filings (one of 5 new listings in the book), a listing rather than a purchase; they opened Kodiak Gas Services Inc and trimmed Astera Labs Inc. Their largest long position is Astera Labs Inc at 12% of the reported non-option book. Cloning the disclosed picks since 2024 would be +24% (+11.7%/yr). That is a simulation of the disclosed long book, not audited returns.
Following at the filing date actually beat the quarter-end book by 2.7 points over this window.
Growth of $10,000 cloning Renaissance Capital LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~36 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.
Top-heavy: focused book
