Given Evolent Health's history of stock price increases following earnings beats, and considering the anticipation of a positive EPS report, there is a high likelihood of a short-term positive impact on EVH's stock price. The historical data provided shows a clear correlation between earnings performance and stock price reaction, suggesting that if EVH beats the EPS estimate again, we could see a similar positive movement. However, the overall negative performance over the last year introduces some uncertainty, hence the confidence score is not at the maximum.
