View all 2354 holding institutions

Across its top 20 institutional holders, APH's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 31/100).

Notable Holders

APH ranks #101 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

APH is a top-conviction position for Egerton Capital — at 8.3% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in APH belongs to BlackRock, Inc., but the position matters far more to Egerton Capital, who has 8.3% 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.

ASR Vermogensbeheer N.V. has added to its APH position for two straight quarters, increasing it by $40.8M to reach $57.0M today.

TD Waterhouse Canada Inc. has trimmed its APH position for two straight quarters, cutting it by $55.4M while still holding $41.2M.

APH is down 2.6% today, but institutions show net buying of $51.2B this quarter — a divergence between today's price move and the underlying institutional flow.

Company Fundamentals

APH posted net income of $5.1B over the trailing twelve months, and currently trades at a P/E of 19.7.

  • Profitable — net income of $5.1B over the trailing twelve months
  • Revenue grew 54.2% year over year
  • Net income improved year over year, from $3.2B to $5.1B
  • Generated $5.4B in positive operating cash flow
  • Current ratio of 2.98x — enough short-term assets to cover short-term liabilities
  • Liabilities run 1.69x equity — within a conventional range

Smart Money Convergence

APH 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.
