The defence industry companies work with governments providing them with military capabilities across land, sea, air, and electronic systems. They help support current and future defence and military needs. Defence stocks, especially those of U.S. companies, have seen an increase following the outbreak of the Hamas-Israeli armed conflict on 7 October 2023.
Defence Companies Whose Stock has Increased
Several defence stocks have increased since the start of the Hamas-Israeli armed conflict.
Northrop Grumman Corp (NYSE: NOC) is one of the largest defence contractors in the world. It was up 11.5% on Monday 9 October from the close of business on Friday 6 October. It continued to rise for that week until 13 October when it closed at $490.15, a 16% increase since 6 October.

In Summary
The above examples show a direct correlation between the outbreak or cessation of conflicts and the increase or decrease in the price of defence stocks.
When conflict occurs, governments reach out to their key strategic defence partners to supply them with military equipment and technology. Increased demand for their products and services leads to an increase in the share price of these companies.

It is interesting to get confirmation in the correlation between the share price movement and certain type of geopolitical event, such as armed conflicts. After all such is the nature of business of Defence corporations and contractors.
Would be educational to explore other factors such as breakthrough R&D and scientific discoveries that cause significant share price movements?
