What Successful Investors Do During Market Stress
In the world of investing, there is a distinct difference between “market noise” and “market signal.” Today, as headlines are dominated by the conflict in Iran and the resulting volatility in energy markets, that distinction has never been more critical.
At Babylon Wealth, we believe that successful investing isn’t about predicting the next geopolitical event; it’s about how you behave once that event occurs. When geopolitical shocks hit, whether it’s the current Iran conflict or past crises like 9/11 or the Gulf War, markets react swiftly. Headlines turn alarming, volatility spikes, and investor behavior often shifts from rational to reactive.
But history tells a different story than emotions.
When markets react to the fog of war, the most successful investors don’t reach for the “sell” button; they reach for their financial plan. Successful investors don’t just survive these periods; they use them.
The Current Moment: War in Iran and Market Behavior
The ongoing conflict involving Iran has triggered sharp—but not unprecedented—market reactions. Since late February 2026, global equities have experienced volatility, with the S&P 500 falling roughly 5% at one point and oil prices surging above $100 per barrel amid supply disruptions.
Markets have been “yo-yoing” on shifting expectations around escalation and ceasefire negotiations, reflecting uncertainty rather than structural collapse.
Interestingly, investor behavior is already diverging:
- Retail investors are reducing individual stock exposure
- Capital is rotating into ETFs, commodities, and defensive assets
- Treasury yields are higher, and precious metals are down
- There is caution and fear
What History Says About War and Markets
Let’s ground this discussion in data.
| Geopolitical Event | Date | Initial Max Drawdown | 1-Year Return After |
|---|---|---|---|
| Pearl Harbor | Dec 1941 | -19.8% | +4.3% |
| Korean War Start | June 1950 | -12.9% | +11.7% |
| Cuban Missile Crisis | Oct 1962 | -6.6% | +27.8% |
| JFK Assassination | Nov 1963 | -2.8% | +14.1% |
| Yom Kippur War / Oil Embargo | Oct 1973 | -16.1% | -43.2%* |
| Iranian Revolution | Jan 1979 | -2.3% | +32.0% |
| Gulf War (Iraq Invades Kuwait) | Aug 1990 | -16.9% | +20.1% |
| 9/11 Attacks | Sept 2001 | -11.6% | -18.4%* |
| Iraq War Start | Mar 2003 | -14.7% | +32.1% |
| Russia–Ukraine War | Feb 2022 | -7.1% | +4.3% |
| Israel–Hamas War | Oct 2023 | -4.5% | +36.0% |
| Iran Conflict | Early 2026 | -5.3%** | TBD |
Note: Data reflects S&P 500 price returns. Past performance is not indicative of future results.
Key insight:
- The average decline across events is relatively modest, ~10%
- Markets typically bottom within weeks and recover within ~1–2 months
- The “V-Shape” Recovery: On average, across 20+ major post-WWII geopolitical shocks, the market has taken only 28 days to return to its pre-event levels.
- Energy vs. Everything Else: Conflicts that involve major oil producers (like the current Iran situation) typically see deeper initial drawdowns due to energy price spikes. However, unless these spikes lead to a prolonged global recession, the recovery is usually robust.
- The 12-Month Rule: Historically, the S&P 500 is higher 80% of the time one year after a major geopolitical shock, with a median return of +10%
- The exceptions—1973 and 2001—were not just geopolitical events. They coincided with deeper economic or energy crises, which is a crucial distinction.
What Successful Investors Actually Do
1. They Separate Noise from Structural Risk
Not every geopolitical event has the same impact on markets. While headlines can make every conflict feel catastrophic, history shows that many wars lead only to short-term volatility.
What matters more is whether the event disrupts the real economy—especially energy markets. That’s why the current Iran conflict is being closely watched. A prolonged disruption to oil supply, particularly through the Strait of Hormuz, could turn a geopolitical shock into a broader economic issue.
Successful investors tune out the noise and focus on what actually drives markets: oil prices, inflation, and interest rates.
2. They Stay Invested (Even When It Feels Wrong)
Market downturns often trigger fear, and the instinct to sell can feel overwhelming. But acting on that impulse is one of the most common and costly mistakes investors make.
Selling during periods of panic tends to lock in losses, while recoveries often happen quickly and unexpectedly. Missing just a few of those rebound days can significantly impact long-term returns.
Investors who succeed understand that markets are resilient over time—and they avoid making emotional decisions in temporary downturns.
3. They Use Volatility as an Opportunity
Volatility can feel uncomfortable, but it often creates opportunity. During market stress, assets are frequently sold indiscriminately, regardless of their underlying quality.
This market action can lead to temporary mispricing, where strong companies trade at discounted valuations. For long-term investors, these moments can offer attractive entry points.
That’s why many institutional investors deploy capital during downturns, rather than waiting for conditions to feel “safe” again.
4. They Rebalance
Staying invested doesn’t mean doing nothing. Successful investors actively manage risk—but they do so with discipline, not panic.
In today’s environment, that often means shifting toward diversification—reducing concentrated positions in individual stocks and increasing exposure to ETFs, commodities, or defensive sectors.
This kind of rebalancing helps maintain alignment with long-term goals, without abandoning the market altogether.
5. They Focus on Time Horizon, Not Headlines
Geopolitical crises can feel overwhelming in real time, but markets are forward-looking. They begin adjusting to future expectations almost immediately.
Even during periods of conflict, economies adapt. Supply chains shift, energy markets rebalance, and policy responses evolve.
Successful investors keep their focus on where things are going—not just where they are today.
When Things Actually Go Wrong
History shows that wars alone rarely cause prolonged bear markets. The real risk arises when conflict spills into the broader economy.
Sustained inflation, major oil supply disruptions, and aggressive interest rate hikes are the factors that tend to drive deeper and longer-lasting downturns. That’s what made the 1973 oil crisis so severe—and why energy markets remain a key variable today.
How We Help You Navigate the Storm
The pattern is remarkably consistent: markets react sharply to shocks, sell off as uncertainty rises, stabilize over time, and eventually recover. The investors who succeed aren’t the ones who predict these events; they’re the ones who respond to them with discipline.
In today’s environment, the playbook hasn’t changed: stay disciplined, stay diversified, and stay invested. Because if history is any guide, periods of uncertainty often create the foundation for future opportunity.
