What is J A Stack's strike rate?

J A Stack has won 67 of 641 runners since 2022, a strike rate of 10.5% (as at 20 October 2026). Figures are computed from our own results archive.

Which course does J A Stack do best at?

Navan by strike rate: 7 wins from 33 runners (21.2%) since 2022. Read from the 15 courses with the most runners on the same basis, and only those with at least 30 — a small sample cannot top the list, and a rarely-visited course is not in the comparison.

Who rides most for J A Stack?

J M Sheridan, with 149 runners since 2022 — 23% of the total. That pairing has won 16 (10.7%).

Is J A Stack in form?

Too few runners in the last 14 days to read — 4 runners, which is not a sample we will draw a conclusion from.

What is J A Stack's Fair A/E?

1.13, from 640 runners with a computed fair probability since 2022. Fair A/E compares actual wins with a margin-stripped market expectation, so 1.00 is par: above it the wins came at bigger prices than the margin-free market implied, below it they did not.

KTB Yard Profile

Sends out around 130 runners a season, almost all on the flat, winning with 11% of them — beating the margin-free market read across five seasons (Fair A/E 1.13). The edge shows sharpest with horses returning fresh: 14% off breaks of two months or more (109 runs).

The read

The record is strongest at Navan (21.2%, n=33), clear of the yard's 10.5% baseline. Horses returning fresh after 61+ days have been a positive signal at 13.8% (n=109, Fair A/E 1.25), but a horse in first-time headgear has been a poor signal at 3.8% (n=52, Fair A/E 0.48). J M Sheridan rides 23% of the entries and matches the yard's average almost exactly (10.7%, A/E 1.04) — the partnership beats the margin-free market read. The yard also reads well on Heavy going (18.8%, n=80) and at trips under 6f (15.5%, n=116). 23 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Jersey Stakes at Ascot (Jun 2026, £99,243). Seasonally, the yard fires Mar–Apr.

Each tile is the record in that situation vs the 10.5% baseline — descriptive splits with the sample always shown, not tips. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races.

Showing the 60 most-raced of the 127 horses sent out in this window — each ran at least 4 times. Horses with fewer runs aren't listed; search finds any horse since 2005. Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

Where they came from · where they went next

Of the 60 horses listed, none arrived from another yard in our archive — all 60 had their first archived run here.

14 have since run for another yard, most often for James Fanshawe (2); 46 have no later run for another yard in our archive.

Read from each listed horse's whole archived career (2005 onwards), not only this window, and counted over the horses listed above, not the whole string. “First archived run” means our archive holds nothing earlier, not that the horse was unraced. A horse with no later run elsewhere may still be here, be off the track, or have run somewhere our archive does not cover — none of that is asserted.
