Why markets work

Sawicky, Jacobin. People often try to write for readers who know no economics, but they rarely succeed. This book is an exception. Make room for two lessons in your mind, and on your bookshelf.

He makes the case that one-lesson economics, based on the idea that market prices are always right, is as useful as a one-wheeled bicycle. If you want to understand what free-market economics gets right, and when governments need to step in, this is the book for you. The 11 sectors are:. This sector classification makes it easy for investors to tailor their portfolios according to their risk tolerance and investment preference.

For example, conservative investors with income needs may weigh their portfolios toward sectors whose constituent stocks have better price stability and offer attractive dividends through so-called defensive sectors such as consumer staples, health care, and utilities. Aggressive investors may prefer more volatile sectors such as information technology, financials, and energy.

In addition to individual stocks, many investors are concerned with stock indices, which are also called indexes. Indices represent aggregated prices of a number of different stocks, and the movement of an index is the net effect of the movements of each individual component. Because of its weighting scheme and the fact that it only consists of 30 stocks when there are many thousands to choose from , it is not really a good indicator of how the stock market is doing.

Investors can trade indices indirectly via futures markets, or via exchange-traded funds ETFs , which act just like stocks on stock exchanges. A market index is a popular measure of stock market performance. Most market indices are market-cap weighted , which means that the weight of each index constituent is proportional to its market capitalization. Keep in mind, though, that a few of them are price-weighted , such as the DJIA.

Stock exchanges have been around for more than two centuries. The venerable NYSE traces its roots back to when two dozen brokers met in Lower Manhattan and signed an agreement to trade securities on commission. In , New York stockbrokers operating under the agreement made some key changes and reorganized as the New York Stock and Exchange Board. The NYSE and Nasdaq are the two largest exchanges in the world, based on the total market capitalization of all the companies listed on the exchange.

The fourth alternative for raising capital is to sell piece of ownership in the corporation to the public. Selling stock in the company can generate huge amounts of cash that can be used for a variety of purposes. When a company begins to sell stock it is said to "go public". The company will usually hire an investment banker to help it go public by evaluating the company, determining a price for the stock, and serving as an intermediary between the company and the investing public.

When a company's stock is sold for the first time it is called an initial public offering or IPO and is sold in the primary market. Then when the stockholders want to resell the stock it is sold on a secondary market, like one of the exchanges. By selling stock the company is transformed from a private business owned by a few people to a public business owned collectively by a large pool of investors. A financial market is a place where firms and individuals enter into contracts to sell or buy a specific product such as a stock, bond, or futures contract.

Buyers seek to buy at the lowest available price and sellers seek to sell at the highest available price. There are a number of different kinds of financial markets, depending on what you want to buy or sell, but all financial markets employ professional people and are regulated. If you want a loan or a savings account you would go to the bank or credit union, if you want to buy stock, a mutual fund or a bond you go to a securities market.

The purpose of a securities market is primarily for business to acquire investment capital. Another securities market is the Over-the-Counter market, where a computer network of dealers buy and sell shares.

Stock markets grew out of small meetings of people who wanted to buy and sell their stocks. These men realized it was much easier to make trades if they were all in the same place at the same time. Today people from all over the world use stock markets to buy and sell shares in thousands of different companies. New issues of stock must be registered with the U. A prospectus, giving details about a company's operation and the stock to be issued is printed and distributed to interested parties.

Investment bankers buy large quantities of the stock from the company and then resell the stock on an exchange. A potential buyer places an order with a broker for the stock he or she wishes to purchase.

The broker then puts in the order to buy on the appropriate exchange, the transaction takes place when someone wants to sell and someone wants to purchase the stock at the same price.

When you purchase a stock, you receive a stock certificate, the certificate may be transferred from one owner to another or can be held by the broker on behalf of the investor. Bonds also can be transferred from one owner to another. As with stocks, buyers go through brokers and dealers. Stocks, bonds, and futures contracts can also be sold in groups as mutual funds. Mutual funds employ professional managers to make decisions about what to buy and sell.

Futures markets provide a way for business to manage price risks. Buyers can obtain protection against rising prices and sellers can obtain protection against declining prices through futures contracts. Example: In the spring, Farmer Jones planted acres of soybeans and he anticipates that in September he will harvest 5, bushels.
