An earnings surprise is the difference between a company's reported EPS or revenue and the analysts' consensus estimate. A positive surprise means results exceeded expectations, while a negative surprise means results fell short.

Earnings reports can increase volatility in UPS stock, especially when reported EPS, revenue or company guidance differs from market expectations. An earnings beat does not always lead to a price increase, as investors also consider the outlook, valuation and broader market conditions.
