Why Does the Stock Market Decline?

What Causes the Stock Market to Go Down During Economic Slowdowns?

When the economy slows down, companies tend to make less profit. With lower sales and thinner margins, their earnings decrease. This causes investors to become concerned that the companies they are invested in will be less profitable in the future. As a result, share prices decline across the stock market as a whole.

For example, during recessions when GDP contracts, the S&P 500 has historically declined over 35% on average. In the 2008 financial crisis, the market fell over 45% during the recession. When companies expect to earn less money in a slowing economy, investors view stock investments as less attractive.

Investor psychology is also key – when people hear about slowing economic growth, they tend to get worried about the future and become more risk averse. This risk aversion further depresses stock prices across the market. Essentially, economic slowdowns make investors worried about lower future company profits, sinking stock prices.

How Can Political Uncertainty Contribute to Stock Market Declines??

During major political events like elections or when significant policy changes are proposed, uncertainty tends to rise among investors. This makes them concerned about the future profitability of companies under new political conditions. As a result, stock prices tend to decrease.

For example, surprise election outcomes like Donald Trump’s 2016 victory have corresponded with 2-4% market declines. The UK Brexit vote led to a 10% drop in the UK stock market. Policy uncertainty regarding taxes or regulations also depresses markets, with a 2020 study finding a 1% increase in US policy uncertainty corresponding to a 60 basis point drop in stock returns.

The psychology is that investors become uncertain about the impacts of political changes on the overall economy. This uncertainty causes them to view equity investments more negatively until the actual impacts become clearer over time. Markets dislike unpredictability, so political uncertainty can catalyze equity drops.

How Do Natural Disasters Contribute to Falling Stock Prices?

When major natural disasters like hurricanes, floods or earthquakes occur, the disruptions to regular business operations can significantly hurt company profits. Supply chains get interrupted, productivity decreases, and costs rise. With lower revenues and higher expenses, corporate earnings suffer following disasters.

For example, Hurricane Katrina corresponded with a 2.5% drop in the S&P 500. Japanese stocks fell over 10% after the major 2011 earthquake and tsunami there. The losses from natural disasters make investors worried about future profitability, so share prices decline market-wide.

Additionally, the uncertainty about the magnitude of business disruptions leads to a pessimistic investor psychology. Fears emerge that some companies may struggle to fully recover or maintain their profit margins following disasters. This amplifies the negative stock market reaction. Essentially, disasters depress investor outlooks on corporate earnings.

How Can Unexpected Events Contribute to Market Declines?

Sudden, unanticipated events can shock investors, stoking fears about how the events could negatively impact the economy and public companies. This uncertainty causes investors to sell equities, driving market drops.

For example, the 2016 Brexit referendum vote shocked investors and promptly sank British stocks over 5% as the nation unexpectedly voted to leave the EU. The market was not prepared for such an outcome, so uncertainty about impacts on British and European companies led to a sell-off.

The psychology is that unexpected, low-probability events make evaluating future profitability difficult. Investors dislike such ambiguity, so markets react negatively. However, the declines are often temporary since markets eventually gain clarity on the actual effects. Nonetheless, surprise events spark uncertainty that can catalyze equity drops.

What Caused the Market Decline on August 16, 2023?

On August 16, 2023, US stocks fell around 0.5-1.15% based on concerns about China’s economy and banks, following discouraging economic data from China. Investors worried that a slowing Chinese economy could spell weaker profits for US multinational companies.

Additionally, bank stocks dropped on recession worries that the Federal Reserve may need to cut interest rates. Lower rates pressure bank profit margins, so bank equities sank. Combined with lingering concerns about inflation, these China and banking factors pushed major stock indexes down on the day.

However, the declines were relatively mild, and stocks remain positive year-to-date. It exemplifies how China or banking news can move markets but that a long-term perspective is wise for investors during periods of volatility.

5 Key Questions About Stock Market Declines

How Long Do Stock Market Declines Typically Last?

Stock market declines vary in duration but usually last from a few weeks to a few months. For example, the median duration of bear markets with declines of 20% or more is about 1.5 months. However, broader market corrections of 10-20% tend to last an average of 4 months.

The depth of the decline also impacts the length – deeper drops tend to have longer recoveries. But markets rebound thanks to the economy’s natural resilience. Patience is key, as markets always recover eventually.

What are the Best Investments During Stock Market Declines?

More conservative investments like dividend stocks, bonds, gold, and cash tend to hold up better during market declines. Dividend stocks offer continued payouts even when prices fall. Bonds provide steady income, and their prices often rise when stocks fall. Gold acts as a hedge, while cash avoids the volatility altogether. Staying diversified across these assets helps minimize risk.

Should I Sell My Stocks During Market Declines?

It’s usually not advisable to sell all your stocks during market declines, as that turns paper losses into realized losses. The market will eventually rebound. But selling small portions to raise cash or rebalance your portfolio can be prudent. Avoid panic selling. Have a long-term perspective and focus on adding money during downturns.

How Can I Protect My Portfolio from Declines?

Having a diversified portfolio that includes conservative assets like bonds, precious metals, cash, and defensive sectors like utilities can help cushion against volatility. Maintaining proper asset allocation and periodically rebalancing also reduces risk. Avoid overexposure to any one stock or sector.

How Can I Take Advantage of Falling Stock Prices?

Market declines allow investors to buy stocks at lower prices, setting up for future gains. So consistently adding money to your portfolio during downturns lets you buy more shares. It establishes a lower average cost basis that amplifies returns during subsequent recoveries. Declines let prudent investors purchase stocks “on sale.”


Stock markets fluctuate up and down for a variety of reasons. While declines can occur unexpectedly, in most cases they are driven by economic slowdowns, political changes, natural disasters, or sudden surprise events that worry investors about future profitability. These factors make investors more risk averse, sinking equity prices across the market through psychological effects.

But understanding the root causes of market declines helps investors think logically when volatility strikes. Maintaining proper portfolio diversification and avoiding panic selling are key. Ultimately, stock markets historically rebound and rise over the long-term. By focusing on the long view and taking advantage of periodic declines to buy at lower valuations, prudent investors can still profit over time. With this comprehensive analysis clarifying why stocks fall, readers are now equipped to make smart investment decisions even during times of market turmoil.
