Stocks are essentially partial ownership of a publicly-traded company.

With a stock, an investor can buy and sell his/her partial ownership of the company at any time and either can make money should the stock’s price rise or lose money if sold under the value paid.

When looking at some of the most impressive companies, the first place to look is the S&P 500. This index measures the performance of 500 companies with the largest presence in the market and shows the general trends of the stock market at any given point.
