About

A simple 70/30 split between SPY and RSP. SPY keeps strong exposure to giants like Apple and Microsoft; RSP evens things out across all 500 names. The blend lowers reliance on a few mega-caps. No timing—just monthly rebalance.
NutHow it works
Hold two S&P 500 funds: 70% in SPY (puts more dollars in the biggest companies) and 30% in RSP (gives every S&P 500 company about the same-sized slice). Each month, reset back to 70/30. This keeps leadership exposure while spreading risk beyond the top 10 stocks.
CheckmarkValue prop
Out-of-sample, the 70/30 SPY/RSP blend outperforms the S&P 500 on risk-adjusted return (Sharpe 2.61 vs 2.15), higher annualized return (26.50% vs 21.77%), and lower drawdown (2.26% vs 2.58%), while preserving broad exposure.

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.
