Live Burst-Warning score: AI index (SOX+NDX) vs broad/defensive (DJI+RSP+XLP+XLV), with an auto-refreshing divergence report. AI Bubble Watch answers one question at a glance: is the market still rewarding the AI leaders, or is money quietly rotating out of them into the broad, defensive market? It builds two live, equal-weight indices from free public market data and compares them: • AI index — PHLX Semiconductors (^SOX) + Nasdaq-100 (^NDX), the heart of the AI/compute trade. • Broad / defensive index — Dow (^DJI), Equal-Weight S&P 500 (RSP), Consumer Staples (XLP) and Healthcare (XLV) — the "average that holds up." A transparent 0–100 Burst-Warning Score distills the leadership picture into GREEN, WATCH, or WARNING, and flags the classic late-cycle pattern where the broad market drifts up while the AI leaders roll over. Click the toolbar icon for an instant score and color-coded gauge. Open the full report for: • A base-100 chart of the AI index vs the broad index, with hover details. • An AI ÷ Broad relative-strength line and its 21-day trend. • Returns across horizons from one week to one year, plus year-to-date. • A full breakdown of how every point of the score is calculated. Lightweight and privacy-friendly: • No sign-in, no API key, no tracking, no ads. • Fetches only public market quotes, on demand. • Uses local browser storage solely to cache results for speed. • Open, inspectable methodology — every number is computed on your device.
