While Alaska Airlines was the operator of the flight in question, the investigation's focus on Boeing's potential criminal liability suggests that Alaska Airlines' direct impact may be limited. However, there could be indirect effects, such as reputational damage or operational disruptions, though these are less likely to significantly affect the stock price in the short term.

The convening of a grand jury by the US Justice Department specifically targeting Boeing for a recent incident significantly raises the stakes for the company. This legal scrutiny could lead to potential fines, sanctions, or other regulatory actions, negatively impacting investor confidence and potentially the stock price in the short term.
