Across its top 20 institutional holders, AMKR's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 43/100).
AMKR ranks #845 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
AMKR is a top-conviction position for Light Street Capital Management, LLC — at 5.7% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in AMKR belongs to BlackRock, Inc., but the position matters far more to Light Street Capital Management, LLC, who has 5.7% 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 AMKR position for two straight quarters, increasing it by $549.8M to reach $1.1B today.
American Century Companies Inc has trimmed its AMKR position for two straight quarters, cutting it by $50.2M while still holding $91.0M.
AMKR is up 3.3% today, and institutions have been net buyers of $1.1B this quarter — today's price move and the underlying institutional flow are pointing the same direction.
AMKR posted net income of $436.1M over the trailing twelve months, and currently trades at a P/E of 26.9.

Top 5 Institutional Movers
AMKR does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
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.
