Ken Fisher: Don’t Fall for This Wartime Investment Mistake
Ken Fisher argues that defense stocks do not perform as many investors expect during geopolitical conflicts. He explains that brief spikes in defense stocks at the start of a conflict typically fade and often lead to underperformance from the conflict's onset. Only unexpected, material increases in global defense spending drive sustained gains in defense stocks.
Summary
In this short commentary, veteran investor Ken Fisher addresses a common misconception about defense stock performance during geopolitical conflicts. He opens by referencing his longstanding characterization of the stock market as 'the great humiliator,' a term he says he has used for decades to describe the market's tendency to confound investor expectations.
Fisher focuses specifically on the behavior of defense stocks when geopolitical tensions or armed conflicts emerge. He notes that while there is typically a brief, sharp rise in defense stocks at the onset of a conflict, this rally is usually short-lived. In most cases, defense stocks subsequently underperform and often end up below where they were at the start of the conflict — a pattern he says has played out in the context of the Iranian conflict referenced in the video.
Fisher then explains what actually drives sustained, meaningful gains in defense stocks: an unexpected and material increase in defense spending, not just in the United States but globally. He emphasizes that it is the surprise element of increased defense budgets — spending above and beyond what markets had already priced in — that creates the conditions for a lasting rally in defense sector equities. A short-duration military conflict, by contrast, does not provide that fundamental catalyst.
He concludes by reinforcing his core message: defense stocks do not behave the way most investors hope or expect when a conflict begins, and falling for that assumption is a mistake he urges investors to avoid.

[0:00] Remember that I've always said I mean when I say always, for decades I've said that the stock market is what I call the great humiliator. Wanting to humiliate as many people as possible. One of the things that people always think as geopolitical issues arise is that this should help defense stocks. If the geopolitical issues arise in a conflict in a spurt there's a very brief sharp rise in defense stocks. It typically doesn't last long and then [0:31] they underperform and in not too long they usually underperform from the beginning of the conflict.
