S&P 500

The S&P 500 (Standard & Poor's 500) is a stock market index tracking the performance of 500 of the largest publicly traded companies in the United States. It is widely regarded as the most accurate barometer of the US equity market and is one of the most closely followed financial benchmarks globally. The S&P 500 serves as the reference index for One-Signal's SPX solution, which has generated 22.80% annualized returns between 2020 and 2025 versus 16.34% for S&P 500 futures buy-and-hold over the same period. The system's beta of 0.111 against the S&P 500 demonstrates that these returns were generated with very low correlation to broader market volatility.
