Across its top 20 institutional holders, TMO's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 33/100).
TMO ranks #80 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
TMO is a top-conviction position for Unisphere Establishment — at 8.8% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in TMO belongs to BlackRock, Inc., but the position matters far more to Unisphere Establishment, who has 8.8% 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.
Sarasin & Partners LLP has added to its TMO position for two straight quarters, increasing it by $50.7M to reach $173.5M today.
Congress Asset Management Co has trimmed its TMO position for two straight quarters, cutting it by $95.4M while still holding $3.0M.
TMO is down 3% today, but institutions show net buying of $82.8B this quarter — a divergence between today's price move and the underlying institutional flow.
TMO posted net income of $7.0B over the trailing twelve months, and currently trades at a P/E of 35.6.

TMO 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.
