Given Universal Display's history of positive stock price reactions to earnings beats and the anticipation of positive guidance, it's likely that a beat or strong future outlook could lead to a short-term increase in the stock price. The company's past performance, including a 3.59% increase after last quarter's earnings beat, supports this expectation. Additionally, the overall 40.36% increase in stock price over the last year indicates a strong bullish sentiment among long-term shareholders, which could be further bolstered by a positive earnings report.
