MGM: Mixed Signals from Institutions and Insiders – Neutral

Signal Basis

Institutional net outflow of $248M (335 sellers vs 250 buyers) indicates distribution, while insiders net bought $37.2M over the past 90 days (buy value $37.2M vs sell value $1.3M), creating a clear divergence. Smart money shows a slight net inflow of $3M, but not enough to outweigh the broader institutional trend.

Confirmation

A slowdown in institutional selling combined with continued insider buying would suggest a bottoming pattern. Continued smart money accumulation would further support this.

Invalidation Risk

Further institutional reduction and a shift to insider selling would increase bearish pressure and invalidate the neutral view.

The scenarios above are AI-generated directly from institutional holders' Form 13F filings on SEC EDGAR and describe historical patterns only. Not investment advice — see the underlying institutional filings linked below.

Smart Money Convergence

MGM does not currently show a 13F-and-insider convergence signal — its insider confidence score is 55/100, below the threshold this product uses to flag combined buying pressure.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
