Key Takeaways

Anyone who wants to grow their wealth should at least consider investing in the stock market. However, one thing to keep in mind is that there is a level of risk that you take on when you make this kind of investment, since the market fluctuates not only from one year to the next, but also within each day. Therefore, before you invest in stocks of any kind, it’s wise to do your research to learn about how it works and what you should anticipate. 

How do people in the United States view the stock market and stock investments? And what are some of the interesting facts surrounding the performance of various stocks over the last few years? 

Below, we take a look at several of the many fascinating stock market stats that showcase just how volatile the market can be, but also how it has grown over the years.  

Top Statistics

  1. More than 50% of U.S. adults had money in the stock market in 2020.6,7
  2. In 2002, 67% of people in the U.S. owned stocks.8
  3. Since 2019, the technology sector has shown the best performance.9
  4. The biggest traded companies by market capitalization in the technology sector of the S&P 500 include Apple, Microsoft, Taiwan Semiconductor, NVIDIA, and Adobe.9 
  5. According to Gallup, 12% of people relied on stocks as a major source of income in 2020.12

S&P 500 Statistics

The index known as the S&P 500 (short for Standard & Poor’s 500) looks at the top—you guessed it—500 companies across 11 sectors in the U.S. It has been around since 1860, and it tracks stock prices so you can get an idea of how the economy and the stock market are doing from one day to the next. And you can also use the S&P 500 to check on how particular industries are performing as well.1,2

Dow Jones Statistics

Formed in 1985, the Dow, which is also known as the Dow Jones Industrial Average or DJIA, is an index that, like the S&P 500, consists of large companies in the U.S. However, there are far fewer, as it focuses on only 30. All of those companies are leaders in their industries.2,3  

 Nasdaq Statistics

Yet another index is the Nasdaq. And you can follow the Nasdaq Composite or the Nasdaq 100.   

2020 Was a Year of Highs and Lows

Because of the COVID-19 pandemic, the stock market took a hit in 2020, but it also recovered surprisingly quickly. On the whole, investors managed to still have a good year despite the setbacks.5

How Americans View Stocks

Although many people might think of professional investors when they imagine the individuals who are buying and selling stocks every day, the truth is that a lot of regular consumers have also made it a point to put their money into the stock market in the hopes of watching it grow by a substantial amount. 

Overall, despite the many fluctuations that the stock market experiences, there has been plenty of growth over the last few years, and even the coronavirus pandemic wasn’t enough to keep stocks down for long. Only time will tell if the stock market continues to be just as resilient against any challenges that might lie ahead in 2023 and beyond.
