About

A simple 100% U.S.-stock mix: 20% Berkshire, 20% S&P 500 fund (VOO), 30% Nasdaq‑100 fund (QQQM), 30% large‑cap growth fund (SCHG). Rebalanced daily, it leans heavily toward big tech and growth versus the broad market.
NutHow it works
Hold four pieces and keep them at fixed weights each day: 20% Berkshire Hathaway (Warren Buffett’s conglomerate), 20% VOO (S&P 500—big U.S. companies), 30% QQQM (Nasdaq‑100—very tech‑heavy), 30% SCHG (fast‑growing large U.S. stocks). No timing—just maintain this mix. This tilts toward big tech and growth.
CheckmarkValue prop
Out-of-sample edge: ~21.9% annualized return, Calmar ~4.72, max drawdown ~4.64%, beta ~0.98. More risk-adjusted growth than the S&P 500 from a simple fixed-4-asset mix with daily rebalance.

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.
