Which funds own FAST

Fastenal Co in the Q2 2026 filings. At least 3 of the 91 current managers on file reported a position, worth $2.1bn between them. It is among the largest positions of fewer than a fifth of the current managers on file. The quarter went the other way: 4 managers trimmed or sold out against 1 buying.

Managers holding: 3; at least, of 91 current
Combined value: $2.1bn; as reported
Opened: 0; new this quarter
Added to: 1; already held
Trimmed or sold out: 4; 2 sold out entirely

Only each manager’s largest 200 positions are listed here, so a smaller holder may be missing.

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.

Sold out of this quarter

Valued at what the position was worth in the previous filing, because by this one it is gone.

Ownership through time

At least 10 of the 95 managers whose filings are on file listed FAST in Q2 2026, against 10 in Q2 2013. The same number as in Q1 2026: 3 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 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.

Managers on file listing it

Their combined reported value

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.

Started in Q2 2026

No manager on file started a position.

What FAST 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.

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.
