Notable Holders

MAR ranks #181 out of 37503 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

MAR is a top-conviction position for Harbor Investment Advisory, LLC — at 13.8% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in MAR belongs to BlackRock, Inc., but the position matters far more to Harbor Investment Advisory, LLC, who has 13.8% 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.

Ken Griffin has trimmed its MAR position for two straight quarters, cutting it by $399.2M while still holding $300.0M.

Game Theory Scenarios

Neutral— Wait & Watch

Institutions accumulate heavily; insiders sell exclusively

Signal Basis

13F filings show institutional net buying of approximately $26.4 billion with 851 net buyers versus 647 net sellers and 193 new positions against 81 exits; however, insider activity over the trailing 90 days reveals 10 sell transactions totaling $34.3 million with zero insider purchases, producing a clear divergence between the two signals.

Confirmation

A subsequent quarter in which insider selling subsides or insider purchases emerge alongside continued institutional accumulation would confirm a bullish convergence.

Invalidation Risk

Sustained insider selling coupled with a meaningful decline in institutional net inflows would shift the balance bearish and invalidate the neutral stance.

AI-assisted, sourced directly from institutional holders' SEC EDGAR Form 13F filings, covering historical data only. Should not be the sole basis for any trade.

Smart Money Convergence

MAR does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, 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.
