Dale Gibbons, Vice Chair and Chief Business Officer of Deposits at Western Alliance, sold 40,000 shares at $82.39 for $3.3M — his verified first-ever sale on this ticker across 142 Form 4 filings dating to 2005 — trimming his stake by 13% from 307,093 to 267,093 shares, with the transaction priced just 1.9% below the 90-day high of $84.03. A 20-year insider choosing to sell for the first time on record, near a multi-month peak and 36 days ahead of earnings, is a notable shift in behavior regardless of the remaining $22M stake. Bull case: stock holds above $73.90 (30d low) into the July 15 earnings print with $2.45 consensus EPS intact; bear case: a break below $73.90 confirms distribution and opens a retest of the $65.45 90-day low.

Where it could go — Broad base rate 50% positive at 90d for this signal type; bull holds $73.90, bear breaks $73.90 toward $65.45.

CAO Ben Mucha sold $482K worth of shares, reducing their stake by 63% at a price just 3.6% below the 90-day high. This is a substantial liquidation but lacks a supporting cluster of buys and occurs against a backdrop of strong analyst optimism.

Where it could go — Analyst mean target not provided; bear case if stock breaks the 30-day low of $73.90.
