Mme A Rosa
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 10 runners a season, across both codes, winning with 7% of them — level with the margin-free market read across the lifetime window (Fair A/E 1.01). New recruits from other yards win at 9% first time out (32 runs).
The record is strongest at Saint-Cloud (FR) (10.8%, n=37), clear of the yard's 6.5% baseline. It is weakest at Chantilly (FR) (0% over 37 runners) — the widest gap in the record. Horses returning fresh after 61+ days have been a poor signal at 3% (n=66, Fair A/E 0.62). The yard also reads well over 1m5f – 2m (12.1%, n=33). The record reads poorly on Standard (AW) going — 1.3% over 77 runners, 5.2pts below the baseline. The market has consistently overbet the yard over 2m1f – 2m4f: Fair A/E 0.35 across 50 runners (2% strike, −40.70 to a £1 stake) — runners there underperform what the price implies.
Yard patterns
the angles behind the record · vs 6.5% baselineEach tile is the record in that situation vs the 6.5% baseline — descriptive splits with the sample always shown, for you to weigh. 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. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

Quick answers
- What is Mme A Rosa's strike rate?
- Mme A Rosa has won 14 of 216 runners since 2008, a strike rate of 6.5% (as at 8 November 2026). Figures are computed from our own results archive.
- Which course does Mme A Rosa do best at?
- Saint-Cloud (FR) by strike rate: 4 wins from 37 runners (10.8%) 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.
- What is Mme A Rosa's Fair A/E?
- 1.01, from 211 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.
