About

A one-fund, buy-and-hold portfolio that invests 100% in SPY to mirror the S&P 500’s performance across major U.S. companies—simple, low maintenance, and fully exposed to stock market ups and downs.
NutHow it works
It puts all the money into one fund: SPY, which aims to match the S&P 500 (500 large U.S. companies). It doesn’t try to time the market. It just buys SPY and holds it. Trades happen mainly when you add/withdraw cash or to keep the single holding at its target.
CheckmarkValue prop
Out-of-sample this strategy tracks the S&P 500 with near-identical returns (~22.60% annually), similar drawdowns (~18.76%), and solid risk metrics (Sharpe ≈1.42, Calmar ≈1.20). Ultra-simple: 100% SPY, buy-and-hold, minimal upkeep.

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.
