Stock Market During War And How It Can Impact Your Portfolio

Stock Market During War And How It Can Impact Your Portfolio

Amid rising global tensions and conflicts—such as the Israel-Palestine situation and the potential nuclear threats posed by Iran and North Korea—it may be worth exploring the economic ripples these crises could create. While these conflicts pose challenges to global peace and safety, they might also indirectly influence economic stability and growth. For example, estimates suggest the U.S. had spent an estimated $8 trillion on post-9/11 wars in the last fiscal year, representing a significant portion of our GDP.

Stock markets during times of war often experience periods of turbulence alongside moments of resilience. Historical patterns suggest that economies and stock markets have demonstrated notable strength in the face of past conflicts. However, for investors, the potential effects of ongoing crises can still feel concerning at times. That’s why we at Cooke Wealth Management carefully examine how these conflicts might impact stocks.

Stock Market During War: World War I and II 

The stock market has historically experienced significant turbulence during wartime, yet it often demonstrates remarkable resilience. When World War I erupted, stocks plummeted by approximately 30%, prompting a four-month closure of the markets. Upon reopening in December 1914, however, the Dow Jones Industrial Average staged an impressive recovery, surging over 88%. World War II followed a similar pattern. Despite initial uncertainty following Hitler’s invasion of Poland in 1939, the U.S. market defied expectations, climbing 10%. After the Pearl Harbor attack in 1941, stocks dipped 2.9% but erased those losses within a month. Although 1942 brought a new low, the market ended the year in positive territory. From 1939 to the war’s conclusion in 1945, the Dow ultimately rose by an impressive 50%. These examples highlight a key insight: while war introduces volatility, markets often adapt and rebound, rewarding those who navigate the uncertainty with patience and perspective.

Unlike the World Wars, the Gulf War had a less significant impact on the stock market. Geopolitical tensions sparked limited volatility, with market performance tracking historical averages. Context matters, as not all conflicts disrupt equally.

Market Resilience and Long-term Trends

While conflicts or the anticipation of war can initially cause market disruptions, escalating geopolitical uncertainty has not typically resulted in sustained or long-term declines. Historically, investors have seen markets rebound to pre-conflict levels within weeks or even months following the onset of hostilities.

The broader trend indicates that sharp sell-offs triggered by war are often brief, with markets recovering swiftly once the situation stabilizes or the conflict's scope becomes clearer. This resilience underscores the importance of not hastily abandoning equities during periods of geopolitical tension. Instead, investors can benefit from understanding historical trends, which provide valuable insights for managing portfolios effectively in such uncertain times.

Investor Responses To War

Conflicts and geopolitical turmoil often lead to instability and uncertainty in the global economy, particularly impacting the stock market. The threat or onset of war can trigger sharp sell-offs in equities, prompting many investors to withdraw their capital from the markets. It’s common to witness stock indexes experience significant declines globally in response to the initial news of conflict.

In the face of such volatility, investors often instinctively seek out 'safe-haven assets.' These assets are viewed as more likely to retain or even appreciate in value during times of crisis, offering a protective cushion against the financial upheaval caused by geopolitical tensions.

Among the most commonly sought-after safe-haven assets are gold, government bonds, and select strong currencies. Gold, with its intrinsic value and limited supply, has historically served as a reliable hedge against economic uncertainty. Government bonds, particularly those issued by stable economies, are often favored due to their relative security and guaranteed returns.

Furthermore, currencies like the U.S. dollar and the Swiss franc are typically seen as stable and resilient, making them preferred choices for investors looking to preserve value amid market volatility.

Understanding Stock Market Behavior In Uncertain Times

Deciphering stock market behavior during times of war can be a complex endeavor. A phenomenon known as 'the war puzzle,' identified by researchers at the Swiss Finance Institute, highlights the seemingly paradoxical behavior of stock prices during wartime. The study reveals that stock prices generally decline as the likelihood of war rises during the prewar phase—no surprise there. However, paradoxically, the outbreak of war itself often leads to a rise in stock prices. On the other hand, when a war begins unexpectedly, without prior warning or buildup, stock prices typically fall instead of rising.

The underlying reason for this counterintuitive behavior remains elusive. It’s as if the market is clouded by uncertainty during the buildup to war. Once war is officially declared, however, the market gains clarity, providing investors with a roadmap—albeit a grim one—which reduces ambiguity and helps guide decision-making. This shift from uncertainty to known factors can often prompt a market rebound, despite the challenges war presents. 

Investor Psychology And The Changing Structure Of Global Markets

Investor reactions to war and conflict are shaped not only by the specific circumstances surrounding the event but also by shifting investor psychology and the evolving dynamics of global markets.

In many cases, investors have responded to war with surprising calm, likely due to growing familiarity with geopolitical crises. This can also be attributed to lessons learned from past stock market recoveries, such as those following the 9/11 attacks and the Great Financial Crisis.

These experiences of resilience allow investors to remain composed in the face of minor events, confident in the market's potential to recover over time.

Additionally, the changing structure of global markets plays a significant role. For example, the U.S. economy has become less susceptible to fluctuations in energy prices, thanks to shifts in global oil markets. As a result, market resilience is driven by a combination of historical endurance, evolving investor sentiment, and the ongoing transformation of global market dynamics. These factors collectively influence the ongoing discourse around stocks during times of war

Stock Performance In World Wars

The outbreak of the World Wars had a profound impact on global stock markets. However, markets displayed intriguing see-saw patterns, with initial declines followed by strong recoveries.

At the onset of World War I, stocks experienced a sharp decline. The uncertainty surrounding the conflict, coupled with its scale, led to a roughly 30% drop in stock prices. In response to the turmoil, the stock markets were closed for approximately six months. However, when the markets finally reopened, they staged a dramatic recovery.

World War II followed a similar pattern. The initial shock of Adolf Hitler's invasion of Poland in 1939 caused a brief slump in stock prices. Yet, this downturn was quickly reversed, with stocks rising by approximately 10% almost immediately thereafter.

Impact on Dow Jones Industrial Average

The Dow Jones Industrial Average (DJIA), a key benchmark for the U.S. stock market, demonstrated remarkable resilience during these conflicts. Despite the initial market declines, the Dow surged by more than 88% in 1915, shortly after the outbreak of World War I.

This trend continued during World War II. Despite the brief dip following the attack on Pearl Harbor, the Dow quickly recovered those losses in less than a month. Over the entire period from 1939 to 1945, the Dow posted a significant cumulative gain of 50%.

The historical stock performance during the World Wars highlights a dynamic resilience that foreshadowed the modern 'buy the dip' strategy. These examples remind investors that, even in the most challenging of times, there is potential for the market to recover and even thrive—underscoring the enduring strength of stocks during periods of war
