This 1 ‘Buy’-Rated Blue-Chip Just Had Its Worst Day Since 2008. Should You Buy the Dip?

The stock market is exiting April on a shaky note. Weighing on sentiment are persistent fears over tariffs and their potential to stall economic growth. Although the market has experienced a few bursts of optimism on strong corporate earnings and hopes of trade war deescalation, several U.S.-listed large-cap stocks have been hit hard. 

In fact, among the hardest-hit in the broader S&P 500 Index ($SPX) is Northrop Grumman (NOC), which nosedived as much as 12.7% on April 22, its steepest single-day drop since the 2008 financial crisis. The defense giant rattled Wall Street with a highly disappointing earnings report for Q1 2025, revealing significant manufacturing cost overruns tied to its B-21 stealth bomber program. Mounting headwinds from tariffs further added to the downfall.
