So far, 2020 has been a hair-raising roller-coaster ride of a year. Exceptional circumstances have led to unprecedented price moves in the financial markets. Some of the established stock market trends have been challenged by recent events and some have been fast-tracked by them.

After a record-breaking run in 2019, most investors were considering the market statistics at the turn of the year and predicting more steady growth. An opportunity to pick up satisfactory if not ground breaking returns. It would be rude not to. Although the first two months of the year followed the game plan, as it turns out, they couldn’t have been more wrong.

If you want to put the year into context, then consider these interesting facts about the stock market.

Key Stock Market Statistics and Facts

  • The total value of the world’s stock exchanges is $95tn — up from $25tn in 2009
  • Approximately 33% of households in the US own taxable investment accounts
  • 53% of those who don’t own stocks say it’s because they can’t afford to invest
  • The best performing major stock index from 2000 to 2020 is the NASDAQ
  • Things are changing — the US middle class is seeing the value of its equity holding diminish

1. The world’s stock markets have doubled in size since 2008

The doubling in value between 2008–2020 provided handsome returns for investors who caught the ride. Those with a longer-term plan could have done even better. In the space of 30 years, between 1990–2020 the stock market increased in size by a multiple of nine.

2. The biggest one-year crash saw global stock markets almost halve in value

The Great Financial Crisis of 2007–2008 wiped 46.6% off the value of global stocks. The financial sector was badly hit, but those 12 months provided a timely reminder that stocks can go down as well as up.

3. The value of stock markets can change dramatically

Given the size of equity market, the moves in cash terms can be eye-watering. In just one month, April 2020, global exchanges increased in value by $7.25tn.

4. The world’s second-largest company Saudi Aramco is still largely privately held

The Saudi Arabian oil giant is one of the world’s largest companies. Its IPO in December 2019 saw 1.9% of ownership transfer to publicly tradable equities, which at that time valued it as the largest firm in the world.

5. In the long-run, stock markets post positive returns

Looking at annual returns of the S&P 500 index (with dividends reinvested) from 1926 to 2018, on average, 1 in 4 years posted a loss. Over a 10-year period, loss-making years come around 5% of the time. One of many interesting stock market facts is that taking a rolling 20-year period stock markets have always posted gains.

6. In 2019, four-times more firms joined an exchange than left one

Some exchange-listed firms ‘delist’ to go back to private ownership, some get bought up and some go bust. There are though always new firms looking to join an exchange and source investor capital.  The trend is that firms continue to look to float. In 2019 there were 2,519 newly listed firms globally and 577 left exchanges.

7. Investors can choose from 53,000 listed firms

Stock exchanges operate globally. The big names such as the NASDAQ are well known, but there are more than 60 major stock exchanges throughout the world, and their range of sizes is quite surprising. The big players still set the rules and analysing stock trends found in Dow Jones statistics is a good place to start.

8. Not only are stock markets getting bigger, but they’re also getting busier too

Between H2 of 2019 and H1 of 2020 equity trading volumes increased dramatically. The highest increase in the number of trades in equities took place in the Americas (66.7%), while APAC and EMEA regions registered only 38.0% and 46.9% increase, respectively.

9. Automated trading is now the norm

More than 80% of stock trading is carried out based on the decisions of algorithms and computer systems. The efficiencies of automated trading help explain the increase in trading activity. In 2019, the number of trades in equities on the NASDAQ exchange was 2,198,488,360,000.

10. Stock markets date back more than 400 years

In 1602, the Dutch East India Co. issued the first paper shares. By providing an exchangeable medium, shareholders were able to conveniently buy, sell and trade their stock with other shareholders and investors. The same principles apply today.

11. Stock markets are getting more stable

A stock market correction is defined by a fall in price of between 10–19%. Since the beginning of 1980, there have been 13 corrections in the S&P 500. At the start of the 20th century, they happened on average every other year.

12. There’s still room to grow

Of the 5.1 million US firms with employees, in 2013, less than 1% of them were listed on a stock exchange. Some of these are large enough to be in line to list. In 2010, private firms in the US accounted for 86.4 % of firms with 500 or more employees.

13. Investors are increasingly likely to invest in international stocks

In the decade between 2010 and 2020, US investors increased their share in the world equity market by almost 15%. Investing in non-US markets is being made easier by less costly and more user-friendly ways to invest internationally.

14. The two major US stock exchanges, the NYSE and NASDAQ account for more than half of the world’s total market capitalisation.

Nasdaq and NYSE statistics show that after it weathered the 2000 crash — the NASDAQ 100 index came of age. But it certainly took its time. The high in March 2000 of 4,816 was followed by 16 years of negative price performance. The percentage increase in the value of the index from Sep 2016 to Sep 2020 is a breath-taking 156% return in only four years.

15. The US dominates the global equity markets, but growth lies elsewhere

In 2019 it was the Hong Kong stock market that once again ranked first globally in terms of IPO launches by value. Despite global uncertainties, it declared its status as the world’s leading IPO hub.

16. Even small US firms are bigger than some entire exchanges

The smallest sized stock on the Nasdaq 100 is struggling retailer Bed Bath and Beyond (NASDAQ: BBBY). Even so, the firm has a market capitalisation ($3.3bn), which is greater than the entire market cap of the national exchanges of Rwanda, Botswana and Bermuda.

17. If you want a wide range of stocks to choose from, look to India

The BSE India Limited exchange holds 5,519 listed companies. This is the largest number globally. The North American exchange with the greatest choice is the TMX Group in Toronto, which has 3,413 listed stocks.

Stock market statistics can be a great tool when looking to make a profitable return from investing. As the standard investment disclaimers confirm, using market statistics and historical data doesn’t guarantee future returns. That being said, identifying stock market trends can be easier to do when studying over a longer time period.

The size of the equity market makes it an obvious place to look to place some capital. Stock ownership statistics point to interesting trends in terms of who is in the game. With so much information on hand, it’s hard to bet against being involved to some extent.
