William Stone
Fair A/E compares wins with a margin-stripped market expectation. Favourite-heavy samples — top yards, leading riders — naturally read a few points warm, so 1.05 means "beat the margin-free market read", not "the market underrates this by 5%".
Sends out around 70 runners a season, almost all on the flat, winning with 9% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.03).
It is weakest at Kempton (AW) (3.7% over 109 runners) — the widest gap in the record. Debutants struggle at 0% (n=51, Fair A/E 0.00). The market has consistently overbet horses returning fresh after 61+ days: 5.4% strike, Fair A/E 0.80 and −93.12 to a £1 stake over 186 runners — those runners underperform what the price implies. Hollie Doyle rides 17% of the entries and edges the yard's average (13.3% vs 9.3%, A/E 1.23) — the partnership beats the margin-free market read. The yard also reads well off a 0-7-day break (16.7%, n=48). The record reads poorly off a break of 180+ days — 1.8% over 55 runners, 7.5pts below the baseline. One Group or Graded win sits in the archive record — the biggest prize the yard has landed: the IRE Incentive Scheme Dick Poole Fillies' Stakes at Salisbury (Sep 2021, £25,520). The stable star of the record: Tigerfish (IRE) — 9 wins from 49 runs for the yard. Seasonally, the yard fires Nov–Jan.
Yard patterns
the angles behind the record · vs 9.3% baselineEach tile is the record in that situation vs the 9.3% 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.

KTB’s figures
the forward record · since 5 Oct 2026KTB’s figures on this yard’s runners since 12 Oct 2026: the KTB Selection in 1 run (won 0) · fastest on KTB Speed in 1 run (won 0) · to 23 Oct 2026.
Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.
Quick answers
- What is William Stone's strike rate?
- William Stone has won 129 of 1,380 runners since 2008, a strike rate of 9.3% (as at 30 October 2026). Figures are computed from our own results archive.
- Which course does William Stone do best at?
- Brighton by strike rate: 10 wins from 65 runners (15.4%) since 2008. 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 William Stone?
- Hollie Doyle, with 241 runners since 2008 — 17% of the total. That pairing has won 32 (13.3%).
- Is William Stone in form?
- Too few runners in the last 14 days to read — 5 runners, which is not a sample we will draw a conclusion from.
- What is William Stone's Fair A/E?
- 1.03, from 1,374 runners with a computed fair probability since 2008. 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.
