Blue Bird is trading 5.65% up at $61.12, alongside a broad U.S. market rally on November 4; this supports a global risk-on explanation, not a confirmed company-specific catalyst. - The S&P 500, Nasdaq and Dow were all higher. - Blue Bird announced a $300 million Georgia manufacturing expansion on October 21, planned to create 375 jobs; available reporting does not establish it as the reason for this session’s rise.
