About

An 80% RSP + 20% SPY mix. It keeps S&P 500 exposure but reduces reliance on a few big tech names. Rebalanced once a year. Tends to help when the broader market participates; can lag when mega-caps drive most gains. Best as a small tilt.
NutHow it works
Put 80% in RSP—the S&P 500 where every company gets roughly the same small slice—and 20% in SPY—the version where the biggest companies dominate. Once a year, move money to restore 80/20 if it drifted. Helps when many stocks rise; lags when a few giants lead.
CheckmarkValue prop
Out-of-sample data show the 80/20 equal-weight blend often outperforms the S&P 500 when breadth leads, reducing mega-cap risk and delivering steadier, potentially higher risk-adjusted returns with an annual 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.
