Jonjo & A.J. O'Neill
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 250 runners a season, almost all over hurdles and fences, winning with 12% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.93).
The record is strongest at Fontwell (23.8%, n=42) and Carlisle (20%, n=45) — all clear of the yard's 12.3% baseline. Debutants struggle at 4.9% (n=61, Fair A/E 0.44). The market has consistently overbet horses returning fresh after 61+ days: 11.3% strike, Fair A/E 0.85 and −93.82 to a £1 stake over 327 runners — those runners underperform what the price implies. Jonjo O'Neill Jr rides 53% of the entries and edges the yard's average (14.9% vs 12.3%, A/E 0.99) — the market has that partnership priced right. The record reads poorly in NH Flat races — 4.8% over 62 runners, 7.5pts below the baseline. The market has consistently overbet the yard in Class 2: Fair A/E 0.65 across 135 runners (6.7% strike, −79.87 to a £1 stake) — runners there underperform what the price implies. 5 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Trustmarque Ultima Handicap Chase at Cheltenham (Mar 2026, £84,405). The stable star of the record: Wilful (IRE) — 6 wins from 13 runs for the yard. Seasonally, the yard fires Aug–Sep.
Yard patterns
the angles behind the record · vs 12.3% baselineEach tile is the record in that situation vs the 12.3% 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.
