View all 920 holding institutions

Across its top 20 institutional holders, MAS's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 35/100).

Notable Holders

MAS ranks #537 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

MAS is a disclosed holding of Bill Nygren (Harris Associates L.P.), one of the tracked superinvestors on AlphaSMO — it makes up 0.9% of that fund's own 13F portfolio.

920 institutions disclose a position in MAS, but none treat it as a major bet — even Beutel, Goodman & Co Ltd., its most concentrated holder, allocates just 2.2% of its own portfolio to it.

Van Eck Associates CORP has added to its MAS position for two straight quarters, increasing it by $168.7M to reach $382.9M today.

Jacobs Levy Equity Management, Inc has trimmed its MAS position for two straight quarters, cutting it by $163.9M while still holding $659.7K.

MAS is down 2.6% today, but institutions show net buying of $2.4B this quarter — a divergence between today's price move and the underlying institutional flow.

Smart Money Convergence

MAS 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.
