It’s the output of a full research desk, distilled to one screen.

How the TrendArc Score works

The TrendArc Score is a single 0–100 conviction reading distilled from our three component lenses — Health, Momentum, and Moat. Higher means a stock the framework views as worth a serious look; lower means caveats the framework wants you to weigh before you commit capital.

The blend is not a textbook weighted average. The weights, the component normalizations, and the distribution shape were arrived at over hundreds of hours of real-money decision-making across our own portfolios — tested against names we already held, names we had rejected, and names we wished we’d caught earlier. We re-ran the same backtests and live-trade audits dozens of times, tuning until the ranking the score produced matched the ranking we’d have written down ourselves after weeks of fundamental work.

What that buys you is a score with the same opinions an experienced analyst would have, delivered in 0.3 seconds across 2,400+ US stocks. The distribution is anchored so that the median large-cap sits near 50, the genuine compounders separate cleanly into the upper quartile, and the structurally damaged names settle in the lower one — without bonus bumps, sentiment overlays, or look-ahead bias smoothing the picture.

We use this score every day, for our own capital. That’s the calibration discipline behind it — the formula stays proprietary because the time and the tested judgment that went into it are what makes the output trustworthy in the first place. The component scores and their drivers are fully visible on every stock’s detail card; the proprietary part is how we weigh and shape them into the final conviction number.
