Given MYR Group's history of stock price volatility post-earnings, the anticipation of beating the EPS estimate and providing positive guidance could lead to a positive short-term impact on the stock price. The historical data indicates that the market reacts notably to MYR Group's earnings announcements, especially when the actual EPS diverges from estimates. The recent upward trend in the stock price and the potential for positive guidance suggest a likely positive investor sentiment leading into the earnings announcement.
