Across its top 20 institutional holders, LRCX's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 37/100).
LRCX ranks #50 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
LRCX is a top-conviction position for Coatue Management LLC — at 8.4% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in LRCX belongs to BlackRock, Inc., but the position matters far more to Coatue Management LLC, who has 8.4% 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.
Annex Advisory Services, LLC has added to its LRCX position for two straight quarters, increasing it by $37.0M to reach $37.2M today.
Y-Intercept has trimmed its LRCX position for two straight quarters, cutting it by $21.3M while still holding $5.2M.
LRCX is down 3.3% today, but institutions show net buying of $228.5B this quarter — a divergence between today's price move and the underlying institutional flow.
LRCX posted net income of $7.3B over the trailing twelve months, and currently trades at a P/E of 48.2.

Top 5 Institutional Movers
LRCX 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.
