Alexis Acker
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%".
Rode around 60 times a season, almost all over hurdles and fences, winning on 9% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.90). Riding last-time-out winners the record reads 18% (66 rides). Rode mostly for M Rolland — 58% of rides in the window.
Rides on last-time-out winners have been a positive signal at 18.2% (n=66, Fair A/E 0.85), but rides in big fields of 14 or more have been a poor signal at 3.9% (n=228, Fair A/E 0.76). The market has consistently overbet first rides on a horse: 4.2% strike, Fair A/E 0.38 and −148.10 to a £1 stake over 240 rides — those runners underperformed what the price implied. M Rolland supplied 58% of the rides and edges the rider's average (10.8% vs 8.6%, A/E 0.96). The rider also read well off a 31-60-day break (13.3%, n=75). The record read poorly off a 8-14-day break — 2.2% over 45 rides, 6.4pts below the baseline. 9 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Prix Renaud du Vivier at Auteuil (FR) (Nov 2009, £117,961). The standout partner of the record was Grand Charly (FR) — 5 wins from 25 rides together. Seasonally, the rider fired Oct–Nov.
Riding patterns
the angles behind the record · vs 8.6% baselineEach tile is the record in that situation vs the 8.6% baseline — descriptive splits with the sample always shown, not tips. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

Quick answers
- What is Alexis Acker's strike rate?
- Alexis Acker has won 54 of 626 rides since 2008, a strike rate of 8.6% (as at 28 October 2026). Figures are computed from our own results archive.
- Which course does Alexis Acker do best at?
- Compiegne by strike rate: 3 wins from 31 rides (9.7%) since 2008. Read from the 15 courses with the most rides 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.
- Which yard does Alexis Acker ride most for?
- M Rolland, with 362 rides since 2008 — 58% of the total. That pairing has won 39 (10.8%).
- What is Alexis Acker's Fair A/E?
- 0.90, from 584 rides 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.
