Boeing shares fall 9.2%, hitting 18-month intraday low

A 9.2% single-session drop to an 18-month intraday low is a sentiment event as much as a price one, signaling that the market's patience with Boeing's narrative has thinned rather than simply repricing near-term numbers. The read-across matters beyond the planemaker itself, given its weight in aerospace supply chains and industrial credit. The open question is whether this proves a one-day air pocket or the start of a sustained de-rating, and what, if anything, management offers to reset the story.
