Dramatic Drops: The Most Notorious Days in Stock Market History
This week sent shockwaves through the stock market, leading to significant daily declines across major indexes. The catalyst? A controversial announcement from President Donald Trump on tariffs, which includes a 10% baseline tariff on all imports, along with higher tariffs on goods from countries like China, Vietnam, and the European Union. As the week progressed, major U.S. stock markets recorded their largest single-day declines since the chaotic trading days of 2020, driven by the pandemic.
Curious how this week stacks up against historical market turmoil? The Hearst Television Data Team took a deep dive into the top 10 single-day declines across three of the most followed stock indices: the Dow Jones Industrial Average, S&P 500, and Nasdaq. These indices not only reflect stock performance but also serve as vital barometers for the health of the economy.
The Dow Jones Industrial Average: A Legacy of Dips
Launched in 1896, the Dow Jones Industrial Average (DJIA) is heralded as the second-oldest U.S. market index and is composed of 30 prominent companies on the New York Stock Exchange. While comprehensive historical data is elusive, S&P Global has pinpointed the days with the most staggering losses ever recorded.
One notable exception is December 12, 1914, which experienced a massive decline after the New York Stock Exchange was shuttered for over four months. Exempting this anomaly, the most catastrophic single-day fall for the DJIA was on Black Monday in 1987, with a jaw-dropping decrease of over 22% from the previous day.
Other historical inflection points include Black Monday and Black Tuesday—two infamous days that initiated the Great Depression in 1929. Those days saw the Dow drop by 12.8% and 11.7%, respectively. Fast forward to this past week, where the Dow also saw notable declines, with an almost 4% decrease on Thursday and a staggering 5.5% fall on Friday—marking the largest daily drops since June 2020. To put this into perspective, these declines rank as the 54th and 24th largest since 1950 based on data from Google Finance.
S&P 500: A Broader Perspective
Following closely in line with the DJIA, the S&P 500 experienced its most significant decrease of 20.5% on Black Monday in 1987. Established in 1957, this index tracks 500 leading U.S. companies and serves as an essential measure for the overall market.
This past week, the S&P 500 fell nearly 6% on Friday, marking it as the 19th largest daily dip since the index’s inception. It’s worth noting that several of the S&P 500’s largest down days correlate with the Great Recession in 2008, highlighting the index’s resilience in the face of adversity.

Nasdaq Composite: The Tech Giant’s Rollercoaster
As the youngest among the three indices, the Nasdaq Composite made its debut in 1971 and includes thousands of technology-centric stocks. Over the past week, its performance has been dramatic, with declines landing among the 30 largest single-day decreases in its history. Thursday saw a decrease of nearly 6%, followed by a 5.82% drop on Friday.
Despite these challenges, it’s essential to understand the characteristic volatility that accompanies tech stocks, often experiencing drastic shifts in both directions.
