RTX scored a contract 5x as big as Palantir's biggest win ever. But is RTX stock cheap enough to buy?

By now, you've probably heard the news: Last month, rising defense technology star Palantir Technologies ( PLTR 1.60% ) won a $10 billion contract from the U.S. Army, consolidating 75 separate, smaller contracts into a single award, guaranteeing Palantir about $1 billion in annual revenue for the next 10 years.

This was big news for Palantir , to be sure. It's almost certainly part of the reason why Palantir stock is up $20 so far this month, adding $45 billion to its market capitalization.
