Under President Trump’s second term, the S&P 500 has experienced both swift declines into correction territory and remarkably quick recoveries, a trend unprecedented compared to other administrations. White House announcements, particularly regarding tariffs and international relations, have emerged as primary drivers for the market’s most significant upswings and downturns.
This headline-driven environment has conditioned investors to embrace volatility and “buy the dip,” necessitating a new investing playbook where the White House’s communication style holds unparalleled sway over market movements and sentiment.
President Donald Trump has been an undeniable force in the stock market, often lauded as the “ultimate stock market president” for overseeing periods of significant expansion to record highs, yet simultaneously acting as a catalyst for major declines.
During the initial two months of what the article refers to as Trump’s second term, the S&P 500 witnessed one of the swiftest descents into correction territory since World War II. This was largely fueled by uncertainties surrounding his tariff policies. Within less than a month, the index nearly entered bear market territory following the president’s “liberation day” tariff announcement. A market correction is typically defined as a fall of 10% to less than 20% from a recent peak, while a bear market signifies a drop of 20% or more on a closing basis.
Despite these sharp downturns, the market has also demonstrated an exceptional ability to recover faster under Trump’s watch. CFRA Research data indicates that S&P 500 pullbacks ranging from 5% to 9.9% since early 2025 have reversed more quickly than the historical median of 34 days. This recovery rate surpasses that observed under any U.S. president since Ronald Reagan in 1981.
“The bull market takes the stairs, whereas bear markets take the elevator,” commented Sam Stovall, chief investment strategist at CFRA Research. “What we're seeing in Trump 2.0 is lower volatility overall combined with a quicker-than-average recovery from sharp sell-offs.” Indeed, the most recent rebound in Trump’s second term saw the S&P 500 recover from a 9.1% decline in just 16 calendar days, tying for the ninth fastest recovery since World War II.
“It's the earnings growth that has caused investors to remain very optimistic,” Stovall added.
A New Era of Market Dynamics
FactSet data reveals robust first-quarter S&P 500 earnings growth, exceeding 20% year-on-year, a performance rivaling the strongest profit expansions since late 2021. This solid earnings backdrop, coupled with significant enthusiasm around artificial intelligence, likely underpinned the market’s recent recovery. However, the initial spark for the upward movement was ignited by hopes for an imminent end to the conflict between the U.S. and Iran.
Last month, Iran and the U.S. reportedly agreed to a ceasefire, which temporarily alleviated concerns about elevated oil prices and inflationary pressures. Yet, this truce has proven fragile, with President Trump recently stating the ceasefire was “on life support.”
“News trumps charts,” noted Ryan Detrick, Chief Market Strategist at Carson Group. “We've been in a very headline-driven world, headline-driven market, and investors have just had to kind of strap on and get on the roller coaster and go along with it.” Detrick believes a global bull market for equities remains intact and is still in its early stages, advising investors to “buy the dip.”
“I don't know we've ever had a market that's this fixated on the day-to-day news coming out of the White House,” he remarked, suggesting that under President Trump, such volatility is a new normal. This reflects a generational shift on Wall Street, where investors, particularly those who experienced the post-global financial crisis era, have become accustomed to treating significant market declines as opportune buying moments.
“FOMO is a very real thing for an institutional investor,” explained Steve Sosnick, chief strategist at Interactive Brokers. Sosnick observed that institutions that sold during Trump’s tariff announcement last year and were slow to re-enter the market subsequently underperformed. This has fostered a “general reluctance of institutions, broadly speaking, to sell too aggressively,” although he cautioned against placing “too much faith in when we get sort of happy talk out of the administration.”
'Don't Fight the White House'
The profound impact of White House announcements on investor sentiment is further highlighted by Fundstrat data, which shows that President Trump has been the primary driver behind both the S&P 500’s five best and five worst days since he reentered office. The market’s best day post-inauguration was April 9, 2025, when the index surged over 9% after he paused widespread tariffs. Conversely, its worst day occurred on April 4, 2025, following China’s retaliatory levies on U.S. goods.
According to Fundstrat, no other U.S. president in almost half a century has been responsible for such a high number of both peak and trough market days during their tenure. Without the five best days directly influenced by Trump in his second term, the S&P 500 would only be up a mere 1% since his inauguration, drastically contrasting with its actual 23.5% gain.
“No other president has had this level of control over the fortunes made in the stock market,” stated Hardika Singh, economic strategist at Fundstrat Global Advisors. She advises a new investment philosophy: “The only strategy investors need to follow is don’t fight the White House, because you’re going to lose and you’re not going to make any money. Throw out your old investing playbook.”
Trump’s distinctive communication style, characterized by frequent social media posts, has undoubtedly amplified market swings and reshaped how future presidents will need to convey messages to Wall Street, believes Matt Gertken, chief geopolitical strategist at BCA Research. “Social media is kind of the name of the game now,” Gertken observed. He suggests that even presidents aiming for a more measured communication approach might eventually adopt some of Trump’s standards due to the evolving media landscape.
Regardless of future presidential communication styles, market volatility appears to be a permanent fixture. Gertken posits that if presidents maintain a low social media profile, the market will “gyrate and vacillate out of speculation,” while frequent, Trump-like pronouncements will cause fluctuations based on each new statement. “There’s no going back,” he concluded.
