The first stock market in the world was the London stock exchange. It was started in a coffeehouse, where traders used to meet to exchange shares, in 1773. The first stock exchange in the United States of America was started in Philadelphia in 1790. The Buttonwood agreement, so named because it was signed under a buttonwood tree, marked the beginnings of New York's Wall Street in 1792. The agreement was signed by 24 traders and was the first American organization of its kind to trade in securities. The traders renamed their venture as New York Stock and Exchange Board in 1817.
That said, learning the logistics of how to buy stocks and earmarking a small sliver of your investable assets to buying individual stocks online can be fun and profitable. And at worst? As long as you don’t put money you can’t afford to lose on the line, stock trading will be a temporary diversion that leads to limited losses, lessons learned and a few self-deprecating stories to entertain dinner guests.
Additionally, many choose to invest via the index method. In this method, one holds a weighted or unweighted portfolio consisting of the entire stock market or some segment of the stock market (such as the S&P 500 or Wilshire 5000). The principal aim of this strategy is to maximize diversification, minimize taxes from too frequent trading, and ride the general trend of the stock market (which, in the U.S., has averaged nearly 10% per year, compounded annually, since World War II).
Replica of an East Indiaman of the Dutch East India Company/United East Indies Company (VOC). The Dutch East India Company was the first corporation to be ever actually listed on an official stock exchange. In 1611, the world's first stock exchange (in its modern sense) was launched by the VOC in Amsterdam. In Robert Shiller's own words, the VOC was "the first real important stock" in the history of finance.
The stock exchanges also maintain all company news, announcements, and financial reporting, which can be usually accessed on their official websites. A stock exchange also supports various other corporate-level, transaction-related activities. For instance, profitable companies may reward investors by paying dividends which usually comes from a part of the company’s earnings. The exchange maintains all such information and may support its processing to a certain extent.
Investor Protection: Along with wealthy and institutional investors, a very large number of small investors are also served by the stock market for their small amount of investments. These investors may have limited financial knowledge, and may not be fully aware of the pitfalls of investing in stocks and other listed instruments. The stock exchange must implement necessary measures to offer the necessary protection to such investors to shield them from financial loss and ensure customer trust.
Each publicly traded company lists their shares on a stock exchange. The two largest exchanges in the world are the New York Stock Exchange (NYSE) and the NASDAQ; both are based in the United States (Wikipedia). Attempting to grasp just how large the NYSE and NASDAQ both are is certainly not easy. The NYSE has a market cap of nearly $31 trillion and the NASDAQ’s is nearly $11 trillion. And yes, that is not a typo, I said, “trillion”.
