If Donald Trump’s Trade War Triggers a Stock Market Crash, History Says This Is the First Thing Investors Should Do

Tensions reached a breaking point over the weekend as trade negotiations between the United States and Canada completely collapsed. President Donald Trump responded swiftly by imposing 50 percent tariffs on various Canadian goods, ranging from whiskey to hockey sticks. The retaliation was immediate, with Canadian Prime Minister Mark Carney pledging to match those tariffs dollar for dollar. This sparked a rapid escalation, leading the president to double tariffs on imported automobiles and auto parts to 50 percent. As expected, the S&P 500 opened lower on Monday morning, reflecting widespread anxiety among traders.

The timing of this dispute is particularly precarious given the current mood of the financial sector. Data from the American Association of Individual Investors indicates that bearish sentiment now outweighs optimism, leaving the market vulnerable to significant volatility. Many analysts fear that if these hostilities continue to climb, it could act as a catalyst for a broader market downturn or even a full scale crash. For many individual investors, the instinct in such a scenario is to scramble for an exit strategy before their portfolios lose any more value.

However, historical data suggests that the most effective reaction to a sudden market plunge is actually to do nothing at all. While it feels counterintuitive to stay put while watching balances drop, panic selling often locks in losses and prevents investors from benefiting when the recovery inevitably begins. Research into past crises shows that markets frequently start their steepest climbs well before a recession officially ends. Those who pull their money out in fear typically miss the window of maximum growth, resulting in significantly lower long term returns compared to those who remained disciplined.

Looking back at events like the pandemic driven crash of 2020 or more recent dips, the pattern remains consistent. The individuals who fared best were not those who timed their exits perfectly, but rather those who stayed invested or even bought more shares at discounted prices during the trough. While no one can predict exactly when a bottom will hit or how long a bear market will last, history serves as a reminder that maintaining a diversified portfolio and resisting the urge to react emotionally is generally the surest path to long term success.
