The market price is the price at which a stock can currently be bought or sold for.
The price can fluctuate as a result of many different things including a company’s reported earnings and when significant changes in management occur (think Steve Jobs and Apple). A market quote is the most recent best bid and ask prices for a given stock. This information is generated by the stock’s specialist, a member of the exchange. A market order, sometimes called an unrestricted order, is an order an investor places with their broker or brokerage service to immediately buy or sell a stock at the best available price.
