About

Own two recent winners and a small cash cushion. ~50% goes to the strongest short‑term small/mid‑cap, ~40% to the strongest recent large/mid‑cap, and ~10% stays in cash. Rebalanced daily; very concentrated and momentum‑driven.
NutHow it works
Every day it splits your money 50/50 into two lists. • Half 1: From a curated set of larger growth names, it buys the single stock that rose the most over the last month and keeps ~20% of this half in cash (a ~10% cash cushion overall). • Half 2: From a smaller, more volatile list, it buys the single stock with the strongest ~2‑week rise. It rechecks daily, so you usually hold 2 stocks plus some cash.
CheckmarkValue prop
Not a core S&P substitute. Out-of-sample results show negative returns and larger drawdowns vs the S&P, but a two-stock momentum sleeve with a cash cushion can serve as a high‑tolerance satellite to diversify risk and seek regime shifts.

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.
