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).
MAS ranks #537 out of 37696 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.
924 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.
Assenagon Asset Management S.A. has added to its MAS position for two straight quarters, increasing it by $17.9M to reach $24.2M today.
Balefire, LLC has trimmed its MAS position for two straight quarters, cutting it by $750.5K while still holding $270.5K.
MAS is up 1.1% today, and institutions have been net buyers of $2.4B this quarter — today's price move and the underlying institutional flow are pointing the same direction.
MAS posted net income of $837.0M over the trailing twelve months.

Top 5 Institutional Movers
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 2026-09-30 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.
