About

A simple buy-and-hold, equal-weight basket of 14 stocks. Heavy tilt to chips/AI and healthcare, plus consumer, materials, insurance, shipping, and Berkshire. No auto-rebalancing—positions drift as winners grow, increasing concentration risk over time.
NutHow it works
Your cash is split evenly across 14 individual stocks, then held. There’s no automatic rebalancing, so faster growers naturally become a bigger slice over time. The mix spans chips/AI (NVIDIA, ASML, KLA), big tech (Microsoft), healthcare (Eli Lilly, Merck, Moderna), consumer (Ulta, Monster), materials (steel, lithium), insurance (Kinsale), energy shipping (FLEX LNG), and Berkshire.
CheckmarkValue prop
Out-of-sample annualized return of 24.83% vs S&P 24.23%, with Calmar ~1.06. A simple 14-stock buy-and-hold tilt toward AI/semis and healthcare offers solid risk-adjusted upside and a transparent, low-turnover approach.

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.
