Best alternatives to PairBook in 2026
If you own more than a couple of stocks or ETFs, there's a decent chance some of them move together more than you realize — which quietly cancels out the diversification benefit you thought you had. PairBook is a free database that's already run the math: it publishes correlation, covariance, beta, volatility, and holdings-overlap analysis for over 52,000 pairs of US-listed stocks and ETFs, so you can check whether two positions are actually diversifying you or just duplicating the same bet. Data refreshes daily after market close, covers 1, 3, and 5-year windows, and is exposed through a free public JSON API that needs no API key and allows cross-origin requests — genuinely usable from a browser-side app, not just a backend. There's also an embeddable SVG badge for showing a correlation figure on your own site, and the methodology is documented publicly.
