View all 675 holding institutions

Across its top 20 institutional holders, MGM's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 8/100, avg. turnover score 41/100).

Notable Holders

MGM ranks #814 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

MGM is a top-conviction position for Mudita Advisors LLP — at 9.4% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in MGM belongs to Davis Selected Advisers, but the position matters far more to Mudita Advisors LLP, who has 9.4% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

California State Teachers Retirement System has added to its MGM position for two straight quarters, increasing it by $200.0M to reach $207.0M today.

Cliff Asness has trimmed its MGM position for two straight quarters, cutting it by $170.8M while still holding $97.8M.

MGM is down 1.4% today, but institutions show net buying of $477.1M this quarter — a divergence between today's price move and the underlying institutional flow.

Company Fundamentals

MGM posted net income of $425.9M over the trailing twelve months, and currently trades at a P/E of 26.5.

  • Profitable — net income of $425.9M over the trailing twelve months
  • Revenue grew 3.2% year over year
  • Net income declined year over year, from $539.5M to $425.9M
  • Generated $2.5B in positive operating cash flow
  • Current ratio of 1.23x — below the conventional 1.5x liquidity buffer
  • Liabilities run 15.68x equity — a highly leveraged balance sheet worth noting

Game Theory Scenarios

Bullish— Smart Money Convergence

Institutional inflow and insider buying converge bullish

Signal Basis

13F filings show a net institutional value increase of approximately $477M for the latest quarter, with smart-money guru net flow of about $483M; insiders bought roughly $37.2M against only $1.3M in sales, yielding a net positive of 962,500 shares.

Confirmation

A cluster alert — three or more insiders buying in the same window — would materially strengthen the bullish case.

Invalidation Risk

With institutional net seller count (322) already exceeding buyer count (312), a reversal in dollar-flow direction would weaken the thesis.

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.
