Amkor Technology Inc in the Q2 2026 filings. At least 5 of the 91 current managers on file reported a position, worth $284m between them.

Managers reporting a position
Largest first. Weight is the share of that manager’s whole reported book, which is the number worth quoting: $400m is a rounding error in one book and a defining bet in another.

Ownership through time
At least 10 of the 95 managers whose filings are on file listed AMKR in Q2 2026, against 1 in Q2 2013. 2 managers fewer than in Q1 2026: 2 started positions; 1 listed it again; 1 sold out, by its own filing; 4 no longer listed it among the positions read, which can mean a holding below the listed range or a filing not yet made.
Each manager’s largest 500 positions a quarter are read, so a small holding in a very large book can be missing, and a manager is counted as leaving only where its own filing shows it.

Between the quarter ends of Q1 2026 and Q2 2026. Each change in shares is valued at the Q2 2026 price, so the price’s own move is left out; a 13F shows the two quarter ends, not when in between anything was bought or sold.

What AMKR is worth
Knowing who owns it is half the question. The other half is what it is worth against the companies it trades beside, which is the one an interviewer will follow up with.
Build the comp set around AMKR →How much of the picture this is
A Form 13F reports US-listed long equity and nothing else: no shorts, no bonds, no cash and no non-US listings. It arrives forty-five days after the quarter ends, so a manager who sold in July still shows the position in a filing published in August. This page reads the managers on file here rather than every filer in the market, and each manager’s largest positions rather than the whole table, so a small position in a very large book may not appear. Say “their last filing showed” rather than “they own”, and the distinction will do you credit.
What to do with a name the funds are buying
Knowing who owns something is the start of a pitch, not the pitch. The next questions are what it is worth and why they were buying.
