President Trump’s claim that the stock market was “stronger than ever” under his policies requires important context that his statement omits. While his first term did deliver substantial market gains—the S&P 500 rose 81.3% from inauguration to his departure in January 2021—his second term tells a markedly different story. During the first year of his second term (January 2025 to January 2026), the S&P 500 gained only 13.3%, marking the weakest start to any presidency in two decades.
This 24.1% difference between first-year performance across his two administrations reveals that market strength under Trump’s policies is not uniform across time. The stock market does not move in isolation from broader economic conditions, Federal Reserve policy, corporate earnings, and geopolitical factors beyond any single president’s control. When Trump took office for his second term, the economy faced different headwinds than 2017—higher interest rates had only recently begun declining, tariff proposals created immediate uncertainty, and valuations were already elevated. To accurately assess Trump’s claim requires separating genuine policy effects from other variables that influence market performance.

Did Trump’s First-Term Policies Drive Stock Market Gains?
trump‘s first term saw impressive market returns across all major indices. The S&P 500 gained 81.3% over four years, the Dow Jones Industrial Average rose 57%, and the Nasdaq Composite surged 142%—the strongest Nasdaq performance under any president since 1981. Tax cuts, deregulation, and pro-business rhetoric created genuine tailwinds for corporate earnings, particularly among large-cap technology firms that drove much of the Nasdaq’s outperformance.
Companies benefited from a reduction in the corporate tax rate from 35% to 21%, which freed capital for stock buybacks, dividends, and reinvestment. However, attributing all market gains to Trump’s policies would be incomplete analysis. The Federal Reserve cut interest rates multiple times beginning in 2019, which typically boosts equity valuations. Corporate profit margins also expanded during this period due to cost-cutting and operational efficiency gains that would have occurred under any administration. The market’s performance from 2017 to 2020 also benefited from the low-rate environment that began under the prior administration, and from the expansion phase of an economic cycle that had begun years earlier. To isolate Trump-specific effects requires acknowledging these overlapping influences.
The Second-Term Reality Versus the Rhetoric
The first year of Trump’s second term delivered substantially weaker stock market performance than comparable periods from his first term. The 13.3% S&P 500 gain from January 2025 to January 2026 lagged the 24.1% return during the first year of his first term by more than 10 percentage points. The full-year 2025 return of 17.9% (including dividends) was respectable by historical standards but did not reflect the surge in enthusiasm that accompanied the initial months of his second term. The April 2025 tariff proposals exposed the contradiction in Trump’s market-friendly narrative.
When he announced new tariffs, the S&P 500 fell nearly 20% from its peak, representing a sharp reproof from the market itself. Although the index subsequently rebounded 32% from its April low, this volatility demonstrated investor concern about trade war risks and their impact on corporate earnings. The market’s reaction suggested that investors were pricing in real costs from tariff policies, not treating them as unambiguous positives for the economy.
Tariff Volatility and Market Uncertainty in 2025
Tariffs represent the clearest policy difference between Trump’s first and second terms, and they have created measurable market volatility. In April 2025, the announcement of proposed tariffs triggered a sharp market correction—an 18-20% decline from peak to trough—as investors recalculated earnings expectations for companies with international supply chains. The rebound that followed suggests the market partially adjusted to tariff expectations, but the initial shock revealed deep uncertainty about implementation and scope. This volatility carries real consequences for ordinary investors.
Retirees and workers with 401(k) plans experience losses during sharp declines, even if markets eventually recover. A 20% drop can wipe out a year’s worth of gains for conservative investors and force some portfolio rebalancing. The broader lesson is that tariffs create uncertainty that markets actively price in as risk, reducing valuations even when companies eventually adapt to the new trade environment. This stands in contrast to Trump’s regulatory rollbacks in the first term, which markets immediately bid upward because the policy direction was clearly pro-business with minimal downside visibility.
How the U.S. Stock Market Ranked Globally in 2025
When measured against stock markets worldwide, the U.S. performance in 2025 appears notably mediocre. With a 16% price return for the year, the S&P 500 ranked 41st out of more than 60 global stock indexes tracked by major investment firms. South Korea’s Kospi index soared 66% over the same 12-month period, Hong Kong’s Hang Seng index gained 28%, and numerous European and emerging-market indexes outperformed American equities. This global comparison matters because it shows that U.S.
market strength cannot be attributed solely to Trump administration policies—markets in other countries with different governments also delivered strong returns. The global context raises an important question: if Trump’s policies were sufficient to drive market gains, why did investors find superior opportunities elsewhere? The answer reflects divergent economic conditions, central bank policies, and valuation starting points across regions. A market that ranks 41st globally cannot reasonably be described as “stronger than ever” in absolute terms, even if it has delivered positive returns. This comparison also suggests that headwinds affecting U.S. equities—whether tariffs, debt concerns, or valuation excesses—may be broader than Trump administration effects alone.
What Actually Drove 2025 Market Performance
Breaking down the components of the 17.9% total return in 2025 reveals what fundamentally moved the market. According to J.P. Morgan analysis, earnings growth contributed 14.3% (comprised of 5.5% sales growth and 8.8% margin expansion), multiple expansion (higher price-to-earnings ratios) contributed 2.1%, and dividends contributed 1.5%. This decomposition shows that earnings drove most of the market’s advance—companies genuinely became more profitable—while valuation expansion provided a smaller boost.
The reliance on earnings growth rather than valuation expansion is actually a healthier foundation for market performance, but it also raises sustainability concerns. If the margin expansion from 2025 proves temporary—driven by one-time benefits like earlier tariff implementation that companies successfully passed to customers—then earnings growth could slow in 2026 and beyond. Additionally, the 8.8% margin expansion that contributed to the stock market’s gain represents real economic costs imposed elsewhere: on consumers through higher prices, on workers if wages don’t keep pace, and on companies operating within tariff-impacted supply chains. A stock market that rises due to margin expansion from tariff inflation may provide poor returns when adjusted for purchasing power losses.
The Role of Investor Expectations and Market Sentiment
Market performance depends heavily on investor expectations, which can shift rapidly based on policy announcements, earnings reports, and economic data. Trump’s first term benefited from markets’ initial enthusiasm for deregulation and tax cuts, which exceeded what actually materialized in terms of economic growth. By the time of the 2020 election, expectations had already normalized, and the pandemic provided a shock that revealed the limitations of tax cuts as a growth driver during a demand crisis.
In the second term, Trump’s return to office was initially greeted positively—stocks rose in anticipation of deregulation and continued business-friendly policies. However, immediate tariff announcements created offsetting headwinds that the market priced as meaningful economic risks. This suggests the market’s 13.3% first-year return reflects balanced optimism and caution, not the euphoria that accompanied the beginning of the first term.
Looking Forward—What the Second-Term Data Suggests
The divergence between Trump’s first and second-term market performance raises questions about policy sustainability and economic cycle positioning. The first term began at the tail end of recovery from the 2008 financial crisis, with significant room for profit margin expansion and economic acceleration. The second term began with the economy already years into an expansion, with unemployment near historic lows and interest rates still relatively high by recent standards. These different starting conditions matter more than policy continuity in explaining why market returns differed.
Going forward, investors will watch whether tariff policies deliver the promised manufacturing renaissance and productivity gains, or whether they prove inflationary and economically costly. The market’s April 2025 reaction suggests skepticism that tariffs will be net-positive, at least in the short term. If tariff-related supply chain disruptions and inflation persist into 2026, earnings growth could slow despite policy support, potentially delivering weaker market returns. The “stronger than ever” claim rests on a selective reading of Trump’s first term while ignoring evidence from his second term that policy alone cannot overcome economic fundamentals.
Conclusion
Trump’s assertion that the stock market was “stronger than ever” under his policies is partially supported by first-term data but contradicted by second-term performance. The 81.3% S&P 500 gain during his first term was genuinely impressive and reflected a combination of tax cuts, deregulation, low interest rates, and a favorable economic cycle. However, the 13.3% gain during the first year of his second term—the weakest such start in 20 years—demonstrates that market strength is inconsistent and depends on factors beyond any single administration’s control.
Tariffs, global economic conditions, and the maturity of the economic cycle all influence returns as much as policy. Investors and citizens should be skeptical of simple narratives about stock market performance as a proxy for policy success. A 13.3% return is respectable historically but falls far short of the “stronger than ever” claim, particularly when global markets delivered superior returns and when the market itself initially penalized tariff proposals with a sharp decline. Real policy assessment requires looking beyond headline market returns to examine earnings quality, sustainability of margins, employment outcomes, and purchasing power—measures that may tell a more complicated story about the actual impact of Trump’s second-term policies on ordinary Americans’ economic wellbeing.
