About

Half Berkshire Hathaway, nearly half the S&P 500 via SPY, plus a small 5% cushion in short‑term US Treasuries (VGSH). Daily rebalancing keeps those weights. Stock‑heavy with a Buffett tilt and a modest safety sleeve.
NutHow it works
It keeps about half in BRK.B (Warren Buffett’s Berkshire Hathaway). The other half is split 90% in SPY (tracks the 500 largest US stocks) and 10% in VGSH (short‑term US Treasury bonds). That nets to 50% BRK.B, 45% SPY, 5% VGSH. It rebalances daily to stay there.
CheckmarkValue prop
Buffett-tilt core with 5% short bond sleeve. Out-of-sample: ~8.9% annualized vs ~15.9% S&P, but max drawdown 9.6% vs 18.8%, Calmar ~0.92 and Sharpe ~0.62—better downside protection with solid returns.

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.
