About

A simple, equal-weight basket of all publicly traded Y Combinator alumni (as of 12/8/2024, excluding Notable Labs), rebalanced daily. Tech-heavy and volatile, mixing large names like Airbnb/Coinbase/DoorDash with smaller, riskier frontier and software firms.
NutHow it works
It holds an equal slice of every Y Combinator alumni company that’s publicly traded as of Dec 8, 2024 (minus Notable Labs). It rebalances each day to keep weights the same. No timing or signals—just a YC list. Mix of big names (Airbnb, Coinbase, DoorDash, Dropbox, GitLab, Instacart, Reddit) and smaller, riskier names (Amplitude, Ginkgo Bioworks, PagerDuty, Matterport, Weave, Rigetti, Momentus, Oklo). Expect tech-heavy ups and downs.
CheckmarkValue prop
A pure, rules-based YC-alumni equity sleeve offering tech exposure beyond the S&P. Out-of-sample shows higher risk (~30% drawdown and negative returns), but it can diversify a core portfolio and offer upside when tech growth accelerates.

FAQ

A Composer symphony is an automated trading strategy that executes trades based on parameters of your choice. Some symphonies are similar to holding one ETF in normal conditions and rotating to a different ETF when market conditions shift, for example a 5% drop in the S&P 500, while others use complex rules with dozens of triggers. However, complex doesn’t always mean better. A simple, well-structured symphony can be just as effective as an intricate one. Learn more about how symphonies work here.
