P/E Ratio: How much money you are paying for $1 of the company's earnings. In other words, if a company is reporting a profit of $2 per share, and the stock is selling for $20 per share, the P/E ratio is 10 because you are paying ten-times earnings ($20 per share divided by $2 per share earnings = 10 P/E.)

Stock: Stock is ownership. A business is divided up into shares of stock and parts of the company (the shares) are sold to investors to raise money. For more information, check out the investing lessons.
Yield: When a company pays a dividend the yield is the percentage of the stock price in relation to the dividend paid. In other words, if a stock is trading for $10 and pays a dividend of $0.50, the yield is 5%, because for every $10 you invest, you would receive 5% back annually in the form of a fifty-cent dividend.
