Lessons From Past Conflicts for Today’s Stock Market

As strikes on Iran continue and the Strait of Hormuz remains effectively closed, it’s clearly too early for market watchers to stop thinking about geopolitical risk. As discussed in recent commentaries but worth repeating, history shows stocks often recover quickly from wars and other military engagements, especially when economies are resilient and earnings fundamentals remain strong. Improved valuations, the strong earnings outlook, and a still-normal level of volatility suggest the risk‑reward backdrop for stocks is getting more favorable. That said, we don’t have market capitulation signals flashing (washed-out selling), nor do we have any more clarity on how the Strait of Hormuz opens up. For now, we believe the best course of action for investors is to be patient and wait for a better entry point to add equity risk.

Stocks Seem to Be Following the Playbook as History Doesn’t Repeat but Often Rhymes

As we wrote about in our March 9 Weekly Market Commentary, stocks have historically been resilient to geopolitical shocks. In the “Stocks Have Historically Been Resilient to Military Conflicts” chart, we focus just on wars and significant military operations to get a more comparable set of events than the broader list we published last month. As the accompanying chart illustrates, even in the face of these more serious and longer-lasting events, the stock market has demonstrated impressive resilience — on average, the S&P 500 draws down 7% and recovers losses within an average of 55 days, or less than two months.

While the latest headlines and commentary from the White House suggest the conflict will be over within the next few weeks, which helped drive stocks higher early last week, disruptions to oil tankers and other shipments through the Strait of Hormuz cannot be ruled out, nor can the risk of further damage to energy facilities or other infrastructure in neighboring Gulf countries. In the event of a ceasefire that opens the Strait of Hormuz, we would expect oil prices to come down. But the price floor is likely higher than February levels in the $50s given what we’ve seen from the Iranian regime. On top of that, how long a possible détente might last — if we get one — remains an open question.

Bottom line, we believe history suggests that it’s quite possible that the 9% peak-to-trough drawdown in the S&P 500 reached in March may be all we get during this conflict. Market watchers may not have to wait too long for stocks to recover from year-to-date losses. At the same time, geopolitical uncertainty remains high enough to warrant patience and leave us comfortable recommending portfolio risk at or slightly below benchmarks currently, although past performance does not guarantee future results.
