Lockheed Martin's stock price has shown to be more sensitive to future guidance than to earnings beats or misses. With a history of positive stock performance following earnings that beat estimates, and a general upward trend over the past year, the short-term impact is likely to be neutral to positive, depending on the actual earnings results and the guidance provided. However, as the market has already priced in expectations, only significant deviations from the forecasted EPS or unexpected future guidance are likely to cause substantial stock movement.
