What Are Stocks?

A stock (also known as equity) is a type of financial instrument that represents fractional ownership of the company that issued the stock. Each unit of stock is called a share, and each share grants the shareholder ownership of a part of the company.. Investors with more shares may potentially earn more from the company and may be able to have greater control over some decisions made at the company.

To understand stocks, think of a business run by five partners. Each partner work together and has an equal ownership, ⅕ of the company In other words, each person has one share (out of five possible shares) in the company. That share confers the right to a proportional amount of the profits, if the company decides to distribute profits vs reinvest, and voting power.

When corporations go public, they issue stock on an exchange. When investors buy this stock, they contribute funds to the company that helps them grow. In return, some of those investors now have the right to vote in shareholder meetings, receive announced dividends, and sell the stock to other investors.

Types of Stocks

There are a variety of stocks available to shareholders, but most investors will buy one of two types of stock: common stocks and preferred stocks.

  • Common Stocks — As the name suggests, common stocks are the most popular type of stock individual investors buy. Owning a common stock allows investors to have voting rights, and earn dividends. Common stocks also have the potential for higher long-term returns, but are also more volatile.
  • Preferred stocks — These types of stock give preferred stockholders different treatment when paying dividends (distribution of profits). They are paid before common stockholders and generally earn higher dividends that are fixed. The returns are often lower, even over the long term, and are less volatile in day-to-day dips and spikes. Preferred stock owners do not have voting rights.

Stocks can be classified into many different types, such as small-cap, mid-cap, and large-cap stocks, international and domestic stocks, and growth and value stocks.

What is the Stock Market?

The stock market consists of exchanges, such as the New York Stock Exchange (NYSE) and the NASDAQ, where stocks are listed. Buyers and sellers come to the stock market to buy and sell shares of stock in companies, which is facilitated by a brokerage firm.

When an investor buys stock, they are hoping that the stock will go up in value. The ultimate goal of an investor is to sell the stock for a profit.

How Does the Stock Market Work?

The stock market fluctuates and is based on supply and demand. If more investors are buying the stock than selling it, the demand for that stock goes up and the value tends to increase. This often results when investors believe the value of the company’s stock will increase as a result of strong financial performance or other market factors. Conversely, when investors believe a stock will perform poorly, they’ll sell it, which floods the market with supply and decreases demand. This lowers the price of the stock. Public Trends shows stock performance over time, helping investors understand long-term movements in stock prices.

In addition to purchasing individual stocks, some investors choose to buy shares in an index fund. These index funds buy a selection of stocks or other assets. To purchase stock, investors need a brokerage account, like those offered by Public.

Company Stock buying & Selling process

Stock Exchanges, Stock Indexes, and the Stock Market

When it comes to investing, the most challenging part is learning the basics of the stock market and understanding the different terms used by investors. Here are a few key terms you’ll see used by investment professionals:

  • Stock Exchange — An exchange is the middleman that connects buyers and sellers who want to trade stocks, bonds and other securities. A well-known example is the New York Stock Exchange (NYSE).
  • Stock Market — The stock market refers to a collection of exchanges where companies list shares of stock for sale. Investors can then buy and sell these stocks among each other.
  • Stock Index — An index gathers data from a variety of industries and helps investors calculate performance. Some indexes even look at specific industries. The three most popular indexes in the US are the Dow Jones Industrial Average, Nasdaq Composite, and the S&P 500.

How are Stock Prices Set?

When a company decides to go public, there will be an initial public offering (IPO) where investors can purchase shares in the company. The company will work with investment bankers to set a primary market price. That initial price is determined by the valuation of the company and perceived demand in the market. These shares will then be offered to preferred institutional and individual buyers.

Companies choose to IPO on a certain exchange, like the New York Stock Exchange (NYSE) or NASDAQ. After the initial offering, the stock becomes available to all individual investors trading on that exchange. At this point, the share price will start to fluctuate based on what buyers are willing to pay and what sellers are willing to accept.

Supply and demand can have a big impact on the stock market. As a company becomes more valuable over time, stock prices can rise, making those stocks valuable to their stockholders.

  • Choose your investments based on facts. Before choosing your stocks, research the background and financial stability of the company. Remember, when you buy stock in a company, you become part-owner, so consider the stock’s price target.

  • Take it slow. Investing in the stock market involves a long time horizon. Start out slow and keep in mind that your strategy should ensure that you can ride out market fluctuations.
  • Diversification is key. The most important thing you can learn about investing is to diversify your assets. Owning stocks in a variety of markets and adding other types of investments can give you a well-balanced portfolio that doesn’t rely on one company’s success, allowing you to recover from a loss more easily.

Minimizing the Risks of Investing in Stocks

The stock market tends to fluctuate, which is why most financial advisors suggest that investors diversify their portfolios. Different asset classes come with their own risks.

Many new investors choose to invest in exchange-traded funds (ETFs), which are securities that are traded like stocks. Bonds, which are loans from an investor to a company or government that are paid back at a fixed rate, are another popular option. While it is historically more volatile than the stock market, many investors also choose to buy cryptocurrency as a way of diversifying their portfolios.

Why Invest in Stocks?

The simple answer is that owning stocks and maintaining a diversified portfolio can help increase your savings over time to help you reach your financial goals. The three most beneficial elements include:

  • Building with a long-term view. Past performance indicates that the stock market will inevitably trend upward. Investing with a long time horizon can help you meet your financial goals.
  • Protect your investments inflation. Investing can provide a hedge against inflation, since the market tends to outperform annual inflation rates.
  • Increase wealth. Building a nest egg for the future requires more than a savings account. Dividend reinvestments compounding over time can work to exponentially increase your savings in the long term.
