View all 1197 holding institutions

Across its top 20 institutional holders, AME's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 33/100).

Notable Holders

AME ranks #359 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

AME is a top-conviction position for Maren Capital LLC — at 10.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in AME belongs to BlackRock, Inc., but the position matters far more to Maren Capital LLC, who has 10.2% 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.

BlackRock has added to its AME position for two straight quarters, increasing it by $690.9M to reach $4.7B today.

EdgePoint Investment Group Inc. has trimmed its AME position for two straight quarters, cutting it by $246.5M while still holding $352.8M.

AME is up 0.8% today, and institutions have been net buyers of $16.3B this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Company Fundamentals

AME posted net income of $1.6B over the trailing twelve months, and currently trades at a P/E of 34.2.

  • Profitable — net income of $1.6B over the trailing twelve months
  • Revenue grew 12.7% year over year
  • Net income improved year over year, from $1.4B to $1.6B
  • Generated $1.8B in positive operating cash flow
  • Current ratio of 1.06x — below the conventional 1.5x liquidity buffer
  • Liabilities run 0.51x equity — within a conventional range

Game Theory Scenarios

Bullish— Smart Money Convergence

Institutions accumulate aggressively; insider signal too thin to offset

Signal Basis

13F filings for the quarter ended 2026-06-30 show net institutional accumulation of $16.26B, with 610 net buyers versus 478 net sellers and 119 new positions against 72 exits — a decisively positive flow. Insider activity is negligible by comparison: one buy of $1.02M and one sell of $1.68M (confidence score 19.85), far too thin to meaningfully counter the institutional signal.

Confirmation

Sustained net institutional buying in the next 13F cycle, with buyer count continuing to exceed sellers, would further confirm the bullish case.

Invalidation Risk

A cluster of insider sells (3+ in the same window) or a reversal to net institutional distribution in subsequent filings would invalidate this outlook.

AI-generated from institutional holders' SEC EDGAR disclosures and limited to historical data. Should not be relied upon as the sole basis for any investment decision.

See the institutional 13F filings behind this signal

Smart Money Convergence

AME does not currently show a 13F-and-insider convergence signal — its insider confidence score is 20/100, 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.

On August 7, 2026, AMETEK announced it has increased the maximum amount it can borrow through its commercial paper program from $2.3 billion to $3.5 billion. The program issues short-term, unsecured notes, and all other material terms are unchanged. The company says the extra room gives it flexibility for general funding needs, including potential acquisitions, and its revolving credit line will continue to back the program, with combined borrowings capped at $3.5 billion.

AMETEK issued a press release on August 4, 2026, reporting its financial results for the three and six months ended June 30, 2026. The 8-K is a routine filing that furnishes the press release as an exhibit rather than re-filing the financials. The excerpt doesn't include the actual revenue or profit figures, so there's nothing here to judge performance by.
