Which funds own MU
Micron Technology Inc in the Q2 2026 filings. At least 47 of the 91 current managers on file reported a position, worth $164bn between them. At least half the current managers on file hold it, so owning it is the consensus rather than a call. The quarter went the other way: 31 managers trimmed or sold out against 17 buying.

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 50 of the 95 managers whose filings are on file listed MU in Q2 2026, against 20 in Q2 2013. 5 managers more than in Q1 2026: 6 started positions; 2 listed it again; 2 sold out, by their own filings; 1 no longer listed it among the positions read, which can mean a holding below the listed range, a filing that reported no holdings, 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.

Reported as options rather than shares

What MU 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 MU →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.
