AI Bubble Watch — Index Divergence

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.
