What PDT Partners LLC changed, 2013 to 2026
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 | |
|---|---|---|---|---|
| Quantbot Technologies LP | at least 16% | 128 | Compare | |
| Voloridge Investment Management LLC | at least 15% | 104 | Compare | |
| AQR Capital Management LLC | at least 13% | 108 | Compare | |
| Renaissance Technologies LLC | at least 13% | 100 | Compare | |
| Two Sigma Investments LP | at least 12% | 100 | Compare | |
| Acadian Asset Management LLC | at least 12% | 108 | Compare | |
| MFS Investment Management | at least 12% | 88 | Compare | |
| Winton Group Ltd | at least 10% | 89 | Compare |
“At least” where either manager has more positions than are read each quarter: a stock both hold below that range is not counted.
The filings behind it

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.
