US Stock Movers: Defense Stocks Rally as Airlines and IBM Slump Post-Earnings

Key Facts

1RTX and Lockheed Martin shares rose following earnings reports that strengthened the defense trade.
2American Airlines and Southwest Airlines shares fell due to fuel cost pressures highlighted in their reports.
3IBM shares lost altitude following the company's earnings release.

As corporate earnings reports continue to shape sector dynamics, major US stocks experienced significant price action following Thursday's opening bell. According to reports, defense contractors RTX and Lockheed Martin saw their shares climb after posting strong financial results that bolstered the defense trade. Conversely, American Airlines and Southwest Airlines shares faced downward pressure due to fuel cost concerns highlighted in their respective reports, while IBM shares also lost altitude following its earnings release.

This divergence highlights the strength of the defense sector relative to the airline industry, which remains sensitive to energy price volatility per market data. IBM's decline post-earnings further underscores the mixed reaction from investors toward large-cap technology results this season. The contrast between the rally in defense stocks and the slump in airlines reflects the broader market's focus on operational efficiency and cost management in the current economic environment.

Regarding current levels, RTX closed at $194.88 and LMT at $514.36 (as of July 22, 2026). In the airline sector, LUV stood at $48.69 and AAL at $15.28 (as of July 21, 2026), while IBM was priced at $205.77 (as of July 22, 2026). Investors are now looking ahead to broader economic indicators and central bank commentary to gauge the next phase of market volatility.
