Highlights

• • Home implied probability (raw) = 83.3%, normalized ~77.4%; our estimated true probability = 78.0%
• • Current home odds (1.20) produce -6.4% ROI by our estimate, so no value

Pros

• + Market reflects heavy favoritism toward the home player, so results are relatively predictable if our conservative estimate is correct
• + Low volatility outcome if the favorite is indeed that likely to win

Cons

• - No positive expected value at available prices (favorite underpriced for profit)
• - Lack of data (form, surface, injuries, H2H) increases uncertainty around our probability estimate

Details

We examined the quoted moneyline (Home 1.20, Away 4.10). The market-implied probability for the home player is about 83.3% (1/1.20) or ~77.4% after normalizing for book margin; with no external form, surface, injury, or H2H data available we make a conservative estimated true probability of the home player winning of 78.0%. At the current home decimal price (1.20) the expected value is p * odds - 1 = 0.78 * 1.20 - 1 = -0.064 (a -6.4% ROI), so there is no positive-value bet on the favorite. The away price (4.10) implies ~22.6% normalized win chance; to back the away player profitably at our estimates we would need to believe her win probability greatly exceeds that implied level, which we cannot justify given the absence of supporting information. Therefore we recommend no bet and specify the minimum fair odds needed for value on our estimated probabilities.

Key factors

• • No external research on form, surface, injuries, or H2H was available
• • Market strongly favors the home player (heavy favorite), which compresses value
• • Bookmaker margin/overround reduces apparent edge at quoted prices
