When you request a quote for a stock, you will receive the bid price and the ask price. The bid price is the best (highest) price you might receive if you sell your stock back to the market. The ask price is the best (lowest) price you might receive if you buy stock from the market.

Will somebody always buy my stocks when I sell them?
No. If you try to sell more shares than people are willing to buy or if your price is unreasonable, it may take a long time for them to sell, if at all. However, if you use market orders on medium or high volume stocks you should not have any problems selling them immediately.

Other people buy stocks based on rumors that the price will rise/fall sharply soon.
Many experienced traders watch financial news on TV, read the relevant newspaper stories, and investigate companies that are in the news. They also use "technical indicators," which are numbers or graphs which may help indicate whether a stock will rise, fall, or stay the same.
A few people will randomly pick stock symbols by throwing a dart at a newspaper, for instance.
What is a mutual fund?
A mutual fund is a fund created by an investment company which combines money from many investors and invests it in a group of stocks, bonds, or other investment vehicles.

What is the P.E. ratio?
The Price to Earnings ratio is simply the price of a company's stock divided by its Earnings Per Share. It is often used as an indicator of whether a stock is overpriced, underpriced, or on par.
