The U.S. stock market is a complicated beast, and with recent events like the COVID-19 pandemic, we've seen some volatility in the last few years. Stocks dipped quite a bit during the pandemic but have recovered since.
To get an idea of how the stock market has fared in the last 10 years, watch trends of major market indices—or certain groups of companies' stocks that give a sample of how the entire market is performing. Perhaps the most well-known market index is the S&P 500, a group of the 500 largest companies on the U.S. stock market.
While the S&P 500 is widely regarded as the best indicator of how the stock market is faring, other market indices can give you a different view based on the type of companies they track. Dow Jones, for instance, follows 30 of the largest companies in the country from various industries. The NASDAQ includes all stocks on the NASDAQ market, largely comprised of tech companies.
By watching the performance of these and other market indices, investors can get a good idea of how the U.S. stock market as a whole has performed over time. Olive Invest examined historical equities data from S&P Dow Jones, NASDAQ, and other data sources to see how the stock market has fared over the last decade.
This chart shows a significant increase in stock index values from the last decade, despite a brief drop in 2020 during the pandemic. At the start of the COVID-19 pandemic, there was a steep drop-off in index values. However, they bounced back by the end of 2020 into 2021.
Index values have held relatively steady growth across the last 10 years. The NASDAQ, S&P 500, and Dow Jones Industrial Average have all doubled in value since 2012.
This chart measures the Chicago Board Options Exchange volatility index (VIX index), designed to show how current events and uncertainty affect stock prices. Essentially, the more fluctuation you see here, the more uncertainty investors and the public have about the future, which can significantly impact the market and even help project market crises.
Unsurprisingly, the most significant spike in volatility from the last decade was in March 2020, at the beginning of the COVID-19 pandemic. The last two years have shown a reduction in volatility since this spike, but in general, there is more uncertainty than 10 years prior.
The S&P 500's annual return on investment is a critical indicator of the stock market's performance. The average return since the S&P 500's establishment is 11%.
There are a few notable data points here—perhaps the most prominent of which is the Great Recession in 2008. That financial crisis resulted in the most significant drop in the S&P 500 return of the last 20 years. Since the recession, however, the rate of return has been above average almost every year.
The S&P 500 tracks the top 500 U.S. companies on the stock market. Knowing what types of businesses make up the majority of the index is essential to understanding which sectors have the most success.
In 2022, Information Technology made up 26.4% of the S&P 500—an industry high in the last 20 years. Similarly, health care is gaining ground in the previous few years, though it is still short of its historical high.
The financial sector has seen a downturn in the last decade—though this may change with the reclassification of major shares next year.
In the last 20 years, there has been a significant drop in how many publicly traded domestic companies are on the U.S. stock market as more companies exit the market and there are fewer IPOs.
The last decade, however, has been far more stable. Experts suggest the change is connected to natural fluctuations and changing dynamics in the market's major industries. McKinsey attributes a significant portion of the drop-off to acquisitions.
Still, there have been fewer IPOs in the last several years, which can be a disappointment for new investors trying to get in on the ground floor.
