Looking back at periods of geopolitical conflict since 1939, S&P 500 returns have historically been higher in the 1, 3, 6, and 12 months following an event, provided the shock does not evolve into a sustained disruption to global energy supply. While markets tend to react quickly, longer-term outcomes are more closely tied to economic fundamentals than the event itself.
Over time, fundamentals usually reassert themselves. Earnings growth, inflation trends and the path of monetary policy tend to ultimately drive market returns.
The implication for investors: Maintaining a diversified portfolio can help navigate periods of uncertainty while remaining positioned for recovery.
1Geopolitical events since 1939 include: WWII - Germany invades Poland and Pearl Harbor, Korean War, Vietnam War, Cuban Missile Crisis, Arab oil embargo, Iranian hostage crisis, USSR in Afghanistan, Gulf War, 9/11, U.S. invades Afghanistan, U.S. invades Iraq, Russia invades Crimea, Russian invades Ukraine, Hamas attacks Israel, U.S. bombs Iran, U.S. Captures Maduro in Venezuela.
