Overview
The S&P 500 Index (^GSPC) is a market-capitalization-weighted index of 500 large-cap US equities maintained by S&P Dow Jones Indices. It is the most widely followed US equity benchmark, covering approximately 80% of total US stock market capitalization. Daily close values are sourced from Yahoo Finance via the macro data pipeline.
Interpretation
- Rising S&P 500 typically signals risk-on sentiment, which historically correlates with Bitcoin upside as capital flows into speculative assets.
- Declining S&P 500 often coincides with risk-off flows — Bitcoin may decouple short-term but extended equity drawdowns tend to compress crypto valuations.
- Compare with NASDAQ Composite to gauge growth/tech vs. broad-market leadership.
- The S&P 500 / BTC ratio reveals whether Bitcoin is outperforming or underperforming traditional equities over a given window.
Use Cases
- Use as a macro backdrop indicator alongside BTC price to assess risk-asset correlation regime.
- Compare with
macro_nasdaq_compositeto track growth vs. value rotation. - Combine with
macro_ust_10y(10Y yield) to evaluate the equity risk premium and its impact on crypto discount rates. - Track the correlation coefficient between S&P 500 and BTC to identify regime shifts (decoupling vs. correlated markets).
