Tracking the S&P 500 · Updated daily after market close
The BATS blends widely-used public market indicators into a single, easy-to-read score. Higher = more bullish. Lower = more oversold. It is not investment advice — just a clear snapshot of where market sentiment sits right now.
What goes into the BATS
Each card below is one ingredient. We blend the live components together, weighted by their historical strength, to produce the BATS.

Where has the BATS been?
The daily BATS reading over time, computed with the same weights and formulas used on the gauge above.
Does the BATS work? — Historical backtest
For every trading day since 2007, we compute the blended BATS from that day's live components (using the same weights shown above), then measure how the S&P 500 actually performed 6 and 12 months later. This is the honest test of whether the combined signal earns its keep.
Real market moments — what did the BATS say?
The aggregate backtest above averages every trading day since 2007. Below are specific moments people actually remember — famous crashes, famous bottoms, famous tops — with the BATS reading on that day and how the S&P 500 performed afterward. This is the "did it work at the moment that mattered?" test.
About the BATS
BATS stands for Benchmark Asset and Trend Scenarios. The BATS combines several well-known market indicators into one number from 0 (very oversold) to 100 (very bullish). Each ingredient is publicly available data — volatility, breadth, momentum, options activity, and more — and we explain on each component's page exactly how it contributes.
The blending logic itself is proprietary: we choose which indicators to include, how to weight them (weights reflect each component's historical predictive power), and how to translate the raw numbers into a single signal.
