53 quarterly 13F filings, from Q2 2013 to Q2 2026, each read from the filing itself. A quarter is compared only with the quarter before it, so a quarter with no filing is a gap in the record, not a sale.

The books most like this one
Among the managers whose filings are on file, at Q2 2026. Overlap is the share of the two books that is the same: for every stock both list, the smaller of its two weights, added up. Two books can overlap because both own the largest companies; it says nothing about whether the managers agree.
| Manager | Overlap | Stocks in both | Overlap over time | |
|---|---|---|---|---|
| Invesco Ltd | at least 25% | 155 | Compare | |
| T. Rowe Price Associates Inc | at least 22% | 136 | Compare | |
| Fidelity (FMR LLC) | at least 22% | 133 | Compare | |
| Capital World Investors | at least 22% | 120 | Compare | |
| Woodline Partners LP | at least 21% | 145 | Compare | |

| Wellington Management Group LLP | at least 21% | 135 | Compare | |

“At least” where either manager has more positions than are read each quarter: a stock both hold below that range is not counted.

Reading this record
A 13F lists US-listed long equity and options at the quarter end, filed up to 45 days later. It shows what was held, not when it was bought or at what price, and nothing short. Where a quarter lists only the largest positions, a name missing from it may still be held below that range; the counts of what was opened and sold always cover the whole filing.
