What is a Value Bet (EV+)?

Uma Value Bet (Bet with Positive Expected Value) This occurs when the actual probability of an event is greater than the implied probability embedded in the odds offered by the bookmaker.

Mathematically, if the Expected Value (EV) is greater than zero, the model has an operational edge over the market in the long run. This is the central guideline used in quantitative analysis to obtain consistent returns over data sampling.

EV Analytical Formula


                    EV = (Odds × (Probability / 100)) - 1

If the final result is greater than zero (> 0%), the model has identified an outlier with a positive statistical value.

Frequently Asked Questions (FAQ)

EV+ stands for Positive Expected Value. It indicates that, statistically, that market operation will return a positive yield if executed repeatedly over a large data sample.

Measurement requires statistical models, such as the Poisson distribution or historical performance analyses. If the model indicates a 60% probability of an event occurring and the bookmaker’s odds are 2.10 (equivalent to 47.6%), there is a calculated value margin.

No. The +EV edge operates under the Law of Large Numbers. Any single event is subject to short-term random fluctuation (variance), but the statistical aggregate tends toward the projected expected return.

Analytical models typically target EV margins between +2% and +8%. Extremely high values (>15%) generally suggest errors in the input parameters or rapid price adjustments by market participants.

Filling in the "Stake" field is optional. When entered, the system calculates the average net profit in local currency (R$) per transaction carried out under that EV margin.
