Investing in stocks is an essential part of many people’s retirement and investment plans. It can also provide opportunities for growth (capital appreciation) over the long term if invested wisely. But investing in stocks can also be very volatile and come with significant risks.
A stock market is a place where buyers and sellers are continuously negotiating prices based on new information, the economic conditions, supply and demand, and other factors. It is not a single entity, but rather an open market with thousands of trading sessions every day around the world.
In the US, it is overseen by the Securities and Exchange Commission, as well as individual state regulators. Its global nature means that a calamity in one region can quickly impact the rest of the world. It is also the main mechanism for distributing wealth, and thus plays a critical role in socioeconomic development and stability.
There are a number of different ways to classify the stock market, but the most common is by market capitalization. This refers to the size of a company relative to the overall market, with shares in large companies often called “blue-chip” stocks and those of small companies being considered “small-cap” shares. There are also “microcap” stocks, which represent shares of very small companies and can be considered speculative. In addition, there are different categories of investors, from institutional to retail. The type of investor determines the types of trades that are done and the level of risk involved.
