Stocks Basics: What Are Stocks?

The Definition of a Stock
Plain and simple, stock is a share in the ownership of a company. Stock represents a claim on the company's assets and earnings. As you acquire more stock, your ownership stake in the company becomes greater. Whether you say shares, equity, or stock, it all means the same thing.


Being an Owner
Holding a company's stock means that you are one of the many owners (shareholders) of a company and, as such, you have a claim (albeit usually very small) to everything the company owns. Yes, this means that technically you own a tiny sliver of every piece of furniture, every trademark, and every contract of the company. As an owner, you are entitled to your share of the company's earnings as well as any voting rights attached to the stock.

A stock is represented by a stock certificate. This is a fancy piece of paper that is proof of your ownership. In today's computer age, you won't actually get to see this document because your brokerage keeps these records electronically, which is also known as holding shares "in street name". This is done to make the shares easier to trade. In the past, when a person wanted to sell his or her shares, that person physically took the certificates down to the brokerage. Now, trading with a click of the mouse or a phone call makes life easier for everybody.

Being a shareholder of a public company does not mean you have a say in the day-to-day running of the business. Instead, one vote per share to elect the board of directors at annual meetings is the extent to which you have a say in the company. For instance, being a Microsoft shareholder doesn't mean you can call up Bill Gates and tell him how you think the company should be run. In the same line of thinking, being a shareholder of Anheuser Busch doesn't mean you can walk into the factory and grab a free case of Bud Light!

The management of the company is supposed to increase the value of the firm for shareholders. If this doesn't happen, the shareholders can vote to have the management removed, at least in theory. In reality, individual investors like you and I don't own enough shares to have a material influence on the company. It's really the big boys like large institutional investors and billionaire entrepreneurs who make the decisions.

For ordinary shareholders, not being able to manage the company isn't such a big deal. After all, the idea is that you don't want to have to work to make money, right? The importance of being a shareholder is that you are entitled to a portion of the company's profits and have a claim on assets. Profits are sometimes paid out in the form of dividends. The more shares you own, the larger the portion of the profits you get. Your claim on assets is only relevant if a company goes bankrupt. In case of liquidation, you'll receive what's left after all the creditors have been paid. This last point is worth repeating: the importance of stock ownership is your claim on assets and earnings. Without this, the stock wouldn't be worth the paper it's printed on.

Another extremely important feature of stock is its limited liability, which means that, as an owner of a stock, you are not personally liable if the company is not able to pay its debts. Other companies such as partnerships are set up so that if the partnership goes bankrupt the creditors can come after the partners (shareholders) personally and sell off their house, car, furniture, etc. Owning stock means that, no matter what, the maximum value you can lose is the value of your investment. Even if a company of which you are a shareholder goes bankrupt, you can never lose your personal assets.

Debt vs. Equity
Why does a company issue stock? Why would the founders share the profits with thousands of people when they could keep profits to themselves? The reason is that at some point every company needs to raise money. To do this, companies can either borrow it from somebody or raise it by selling part of the company, which is known as issuing stock. A company can borrow by taking a loan from a bank or by issuing bonds. Both methods fit under the umbrella of debt financing. On the other hand, issuing stock is called equity financing. Issuing stock is advantageous for the company because it does not require the company to pay back the money or make interest payments along the way. All that the shareholders get in return for their money is the hope that the shares will someday be worth more than what they paid for them. The first sale of a stock, which is issued by the private company itself, is called the initial public offering (IPO).

It is important that you understand the distinction between a company financing through debt and financing through equity. When you buy a debt investment such as a bond, you are guaranteed the return of your money (the principal) along with promised interest payments. This isn't the case with an equity investment. By becoming an owner, you assume the risk of the company not being successful - just as a small business owner isn't guaranteed a return, neither is a shareholder. As an owner, your claim on assets is less than that of creditors. This means that if a company goes bankrupt and liquidates, you, as a shareholder, don't get any money until the banks and bondholders have been paid out; we call this absolute priority. Shareholders earn a lot if a company is successful, but they also stand to lose their entire investment if the company isn't successful.

Risk
It must be emphasized that there are no guarantees when it comes to individual stocks. Some companies pay out dividends, but many others do not. And there is no obligation to pay out dividends even for those firms that have traditionally given them. Without dividends, an investor can make money on a stock only through its appreciation in the open market. On the downside, any stock may go bankrupt, in which case your investment is worth nothing.

Although risk might sound all negative, there is also a bright side. Taking on greater risk demands a greater return on your investment. This is the reason why stocks have historically outperformed other investments such as bonds or savings accounts. Over the long term, an investment in stocks has historically had an average return of around 10-12%.

Stock Basics Tutorial

Wouldn't you love to be a business owner without ever having to show up at work? Imagine if you could sit back, watch your company grow, and collect the dividend checks as the money rolls in! This situation might sound like a pipe dream, but it's closer to reality than you might think.
As you've probably guessed, we're talking about owning stocks. This fabulous category of financial instruments is, without a doubt, one of the greatest tools ever invented for building wealth. Stocks are a part, if not the cornerstone, of nearly any investment portfolio. When you start on your road to financial freedom, you need to have a solid understanding of stocks and how they trade on the stock market.
Over the last few decades, the average person's interest in the stock market has grown exponentially. What was once a toy of the rich has now turned into the vehicle of choice for growing wealth. This demand coupled with advances in trading technology has opened up the markets so that nowadays nearly anybody can own stocks.
Despite their popularity, however, most people don't fully understand stocks. Much is learned from conversations around the water cooler with others who also don't know what they're talking about. Chances are you've already heard people say things like, "Bob's cousin made a killing in XYZ company, and now he's got another hot tip..." or "Watch out with stocks--you can lose your shirt in a matter of days!" So much of this misinformation is based on a get-rich-quick mentality, which was especially prevalent during the amazing dotcom market in the late '90s. People thought that stocks were the magic answer to instant wealth with no risk. The ensuing dotcom crash proved that this is not the case. Stocks can (and do) create massive amounts of wealth, but they aren't without risks. The only solution to this is education. The key to protecting yourself in the stock market is to understand where you are putting your money.
It is for this reason that we've created this tutorial: to provide the foundation you need to make investment decisions yourself. We'll start by explaining what a stock is and the different types of stock, and then we'll talk about how they are traded, what causes prices to change, how you buy stocks and much more.

Economics Basics: Conclusion

We hope that this has given you some insight to the market and, in turn, your investment strategies. Let's recap what we've learned in this tutorial:

• Economics is best described as the study of humans behaving in response to having only limited resources to fulfill unlimited wants and needs.
• Scarcity refers to the limited resources in an economy. Macroeconomics is the study of the economy as a whole. Microeconomics analyzes the individual people and companies that make up the greater economy.
• The Production Possibility Frontier (PPF) allows us to determine how an economy can allocate its resources in order to achieve optimal output. Knowing this will lead countries to specialize and trade products amongst each other rather than each producing all the products it needs.
• Demand and supply refer to the relationship price has with the quantity consumers demand and the quantity supplied by producers. As price increases, quantity demanded decreases and quantity supplied increases.
• Elasticity tells us how much quantity demanded or supplied changes when there is a change in price. The more the quantity changes, the more elastic the good or service. Products whose quantity supplied or demanded does not change much with a change in price are considered inelastic.
• Utility is the amount of benefit a consumer receives from a given good or service. Economists use utility to determine how an individual can get the most satisfaction out of his or her available resources.
• Market economies are assumed to have many buyers and sellers, high competition and many substitutes. Monopolies characterize industries in which the supplier determines prices and high barriers prevent any competitors from entering the market. Oligopolies are industries with a few interdependent companies. Perfect competition represents an economy with many businesses competing with one another for consumer interest and profits.

Economics Basics: Monopolies, Oligopolies and Perfect Competition

Economists assume that there are a number of different buyers and sellers in the marketplace. This means that we have competition in the market, which allows price to change in response to changes in supply and demand. Furthermore, for almost every product there are substitutes, so if one product becomes too expensive, a buyer can choose a cheaper substitute instead. In a market with many buyers and sellers, both the consumer and the supplier have equal ability to influence price.
In some industries, there are no substitutes and there is no competition. In a market that has only one or few suppliers of a good or service, the producer(s) can control price, meaning that a consumer does not have choice, cannot maximize his or her total utility and has have very little influence over the price of goods.
A monopoly is a market structure in which there is only one producer/seller for a product. In other words, the single business is the industry. Entry into such a market is restricted due to high costs or other impediments, which may be economic, social or political. For instance, a government can create a monopoly over an industry that it wants to control, such as electricity. Another reason for the barriers against entry into a monopolistic industry is that oftentimes, one entity has the exclusive rights to a natural resource. For example, in Saudi Arabia the government has sole control over the oil industry. A monopoly may also form when a company has a copyright or patent that prevents others from entering the market. Pfizer, for instance, had a patent on Viagra.
In an oligopoly, there are only a few firms that make up an industry. This select group of firms has control over the price and, like a monopoly, an oligopoly has high barriers to entry. The products that the oligopolistic firms produce are often nearly identical and, therefore, the companies, which are competing for market share, are interdependent as a result of market forces. Assume, for example, that an economy needs only 100 widgets. Company X produces 50 widgets and its competitor, Company Y, produces the other 50. The prices of the two brands will be interdependent and, therefore, similar. So, if Company X starts selling the widgets at a lower price, it will get a greater market share, thereby forcing Company Y to lower its prices as well.
There are two extreme forms of market structure: monopoly and, its opposite, perfect competition. Perfect competition is characterized by many buyers and sellers, many products that are similar in nature and, as a result, many substitutes. Perfect competition means there are few, if any, barriers to entry for new companies, and prices are determined by supply and demand. Thus, producers in a perfectly competitive market are subject to the prices determined by the market and do not have any leverage. For example, in a perfectly competitive market, should a single firm decide to increase its selling price of a good, the consumers can just turn to the nearest competitor for a better price, causing any firm that increases its prices to lose market share and profits.

Economics Basics: Utility

We have already seen that the focus of economics is to understand the problem of scarcity: the problem of fulfilling the unlimited wants of humankind with limited and/or scarce resources. Because of scarcity, economies need to allocate their resources efficiently. Underlying the laws of demand and supply is the concept of utility, which represents the advantage or fulfillment a person receives from consuming a good or service. Utility, then, explains how individuals and economies aim to gain optimal satisfaction in dealing with scarcity.
Utility is an abstract concept rather than a concrete, observable quantity. The units to which we assign an "amount" of utility, therefore, are arbitrary, representing a relative value. Total utility is the aggregate sum of satisfaction or benefit that an individual gains from consuming a given amount of goods or services in an economy. The amount of a person's total utility corresponds to the person's level of consumption. Usually, the more the person consumes, the larger his or her total utility will be. Marginal utility is the additional satisfaction, or amount of utility, gained from each extra unit of consumption.
Although total utility usually increases as more of a good is consumed, marginal utility usually decreases with each additional increase in the consumption of a good. This decrease demonstrates the law of diminishing marginal utility. Because there is a certain threshold of satisfaction, the consumer will no longer receive the same pleasure from consumption once that threshold is crossed. In other words, total utility will increase at a slower pace as an individual increases the quantity consumed.
Take, for example, a chocolate bar. Let's say that after eating one chocolate bar your sweet tooth has been satisfied. Your marginal utility (and total utility) after eating one chocolate bar will be quite high. But if you eat more chocolate bars, the pleasure of each additional chocolate bar will be less than the pleasure you received from eating the one before - probably because you are starting to feel full or you have had too many sweets for one day.

This table shows that total utility will increase at a much slower rate as marginal utility diminishes with each additional bar. Notice how the first chocolate bar gives a total utility of 70 but the next three chocolate bars together increase total utility by only 18 additional units.
The law of diminishing marginal utility helps economists understand the law of demand and the negative sloping demand curve. The less of something you have, the more satisfaction you gain from each additional unit you consume; the marginal utility you gain from that product is therefore higher, giving you a higher willingness to pay more for it. Prices are lower at a higher quantity demanded because your additional satisfaction diminishes as you demand more.
In order to determine what a consumer's utility and total utility are, economists turn to consumer demand theory, which studies consumer behavior and satisfaction. Economists assume the consumer is rational and will thus maximize his or her total utility by purchasing a combination of different products rather than more of one particular product. Thus, instead of spending all of your money on three chocolate bars, which has a total utility of 85, you should instead purchase the one chocolate bar, which has a utility of 70, and perhaps a glass of milk, which has a utility of 50. This combination will give you a maximized total utility of 120 but at the same cost as the three chocolate bars.
