What XRay does

Institutional analysis,
no institution required

Most portfolio tools show you what you hold. XRay shows you what you really own — and what happens when markets move.

🔍
True fund look-through
XRay looks inside every ETF and mutual fund to show your real company-level exposure. NVIDIA appearing in 6 of your funds? You'll see the combined total instantly.
⛓
Correlation cascade stress test
When NVIDIA drops 40%, AMD, Broadcom and Microsoft don't stay flat. XRay propagates shocks through a live correlation matrix to show the full ripple — not just the direct hit.
Unique feature
📈
Generational growth projection
Each position projected using its own verified historical CAGR over up to 100 years. Custom rate slider. Built for long-term and generational wealth planning.
🎯
Iconic investor models
Compare your portfolio against Buffett, Cathie Wood, Peter Lynch, Ray Dalio, David Swensen, and Ron Baron. See exactly what to trim and where to add.
📊
Holdings ledger
Every position across all accounts — summed, sorted, and showing gain/loss to the dollar. Missing Fidelity gain data? XRay calculates it from your cost basis automatically.
💰
Live dividend tracker
Connect your free Finnhub API key and see your estimated annual dividend income, total portfolio yield, and monthly income run rate — updated live.
Live data
🌡️
7 macro stress scenarios
Rate change, oil, dollar index, gold, CPI, PPI, GDP — each with calibrated sector sensitivities based on real historical data. Slide and watch your portfolio react.
🔀
Fund overlap analysis
Holding VGT, QQQ, and VIGAX? XRay shows which companies appear in multiple funds and by how much — so you know your true concentration before the market tells you.
📉

Black-Scholes delta computed live from your CSV. Net delta per underlying, total dollar exposure, and how spreads behave under each stress scenario.

The ripple effect most tools ignore

When NVIDIA drops 40%, it doesn't happen in isolation. Broadcom, AMD, Microsoft and Meta all move. XRay uses a 30×30 correlation matrix to calculate exactly how much — and shows you the full damage, not just the direct hit.
