Given AES's history of stock price movements following earnings reports and guidance announcements, there is a potential for positive short-term impact if AES beats the EPS estimate and provides favorable future guidance. The anticipation of this event, based on past performance where a beat in EPS estimate led to an 8.32% increase in stock price, suggests a likely positive reaction if the trend continues. However, the overall negative performance over the past year indicates investor sentiment may be cautious.
