ETF Insider

etfinsider.co

Editor’s pick Hands-on review

ETF & mutual fund overlap/correlation and portfolio visualization tool featuring Sankey look‑through, correlation matrices, and efficient‑frontier (Sharpe) views. Free tier allows up to 4 saved portfolios and limited full‑holdings visibility; Pro ($14/mo) unlocks unlimited portfolios, full holdings depth, and Excel export. Enterprise adds a financial data API, custom reports/visualizations, and white‑label options. Coverage explicitly includes **US‑listed ETFs & mutual funds**; equities coverage is described as **international** on pricing, but the FAQ states non‑US assets not listed in the US are not supported (current constraint). Holdings are sourced primarily from SEC EDGAR and refreshed on a quarterly cadence based on filings; data may be delayed per exchanges/providers.
