Boeing (BA) shares surged 5.07% during Monday's intraday trading session, reflecting strong investor optimism following a series of positive catalysts.

The primary driver was a rare double-notch upgrade from BNP Paribas, which lifted its rating on Boeing to Outperform from Underperform and raised its price target to $300. The upgrade, noted by multiple analysts as a significant bullish signal, fueled a rally in the stock as 80% of analysts now rate Boeing a Buy with a mean price target of $276.16.

Further boosting sentiment, Boeing announced the delivery of Somon Air's first 737 MAX aircraft, the first of two scheduled for the carrier and the first 737 MAX to enter service in Tajikistan. This milestone underscores Boeing's ongoing delivery momentum and the recovery of its commercial airplane business.
