Defense penny stocks live at the intersection of government contracts and geopolitical cycles. The big primes (Lockheed, Northrop, RTX) get the headlines; sub-$5 names are specialists — drone subcomponents, software contractors, niche electronics. Their stock behavior is bimodal: long stretches of low volatility punctuated by sharp moves on contract wins, congressional appropriations news, or geopolitical events.
See also: quantum computing (government contract overlap), nuclear power (national security relevance), penny stocks under $1.
