Index
A financial index is a measurement of the performance of a group of assets — typically stocks, bonds, or commodities — used as a benchmark for market performance. The S&P 500 is one of the most widely followed equity indices globally, representing 500 of the largest US-listed companies. Indices serve as reference points for portfolio performance and as the underlying basis for many tradeable instruments including futures, ETFs, CFDs, and options. One-Signal uses the S&P 500 as the reference index for its SPX solution. Between 2020 and 2025, the One-Signal SPX solution generated 22.80% annualized returns versus 16.34% for S&P 500 futures buy-and-hold over the same period.
