About

A simple, fixed‑weight U.S. stock portfolio: 20% Berkshire Hathaway, 20% S&P 500 (VOO), 30% Nasdaq‑100 (QQQM), 30% U.S. large‑cap growth (SCHG). Rebalanced daily. Heavy tilt to mega‑cap growth/tech; Berkshire adds a diversified, quality ballast.
NutHow it works
It keeps a fixed mix of four U.S. stock holdings and resets to these weights each day: - 20% BRK.B: Berkshire Hathaway (Buffett’s conglomerate: insurance, railroad, utilities, lots of cash). - 20% VOO: S&P 500 fund (broad U.S. market). - 30% QQQM: Nasdaq‑100 fund like QQQ but with a lower fee; very tech‑heavy. - 30% SCHG: U.S. large‑cap growth fund (Apple, Microsoft, Nvidia, Alphabet, etc). Net effect: 100% stocks, tilted to big‑growth/tech; Berkshire adds some balance.
CheckmarkValue prop
Out-of-sample Sharpe ~1.61 and Calmar ~2.06 with beta ~1: a disciplined fixed-weight U.S. equity mix (mega-cap growth with Berkshire ballast) offering strong risk-adjusted upside and transparent, rules-based returns vs. the S&P 500.

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.
