About

100% SPY with daily rebalancing to be the sole holding, providing a simple, passive bet on the US stock market (S&P 500).
NutHow it works
What you need to know in plain language: 1) You invest only in SPY, a fund that mirrors the S&P 500. 2) The plan checks every day to keep the entire portfolio in SPY (100% SPY). 3) If SPY moves, your portfolio value moves with it. 4) There are no other assets, no sector bets, and no market timing. It’s simply a passive bet on the US stock market.

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.
