Embraer is trading at $73.56, down 6.32%, amid a broad risk-off selloff, with no clear company-specific catalyst. - The S&P 500, Nasdaq, and Dow are all sharply lower, with technology stocks leading the decline. - Embraer announced a six-jet Wheels Up purchase agreement on November 5, a positive development rather than an evident cause of the drop. - IndiGo talks were reported November 4 and do not explain today’s decline.
