A monopoly and an oligopoly are market structures that exist when there is imperfect competition. A monopoly is when a single company produces goods with no close substitute, while an oligopoly is when a small number of relatively large companies produce similar but slightly different goods. In both cases, significant barriers to entry prevent other enterprises from competing. A market’s geographical size can determine which structure exists.

The stock market is often a sentiment indicator and can impact gross domestic product (GDP). GDP measures the output of all goods and services in an economy. As the stock market rises and falls, so too, does sentiment in the economy. As sentiment changes, so do people’s spending, which ultimately drives GDP growth; however, the stock market can have both negative and positive effects on GDP.
