To make comparisons between companies, sectors and markets a little easier, there are a number of mathematical models used. The most common and often the most helpful is the P/E ratio. The Price to Earnings ratio takes the share price and is divided by the earnings per share. It is possible to calculate this using past earnings, projected future earnings and with all sorts of moving averages ;-) Therefore, this is one number that it is vital for any investor to know and understand.

Dividends are quarterly payments companies send out to their shareholders. Dividend investing refers to portfolios containing stocks that consistently issue dividend payments throughout the years. These stocks produce a reliable passive income stream that can be beneficial in retirement. You can't judge a stock by its dividend price alone, however. Sometimes companies will increase dividends as a way to attract investors when the underlying company is in trouble. If a company is offering high dividends, ask yourself why management isn't reinvesting some of that money in the company for growth.
A stock split is when a company increases its total shares by dividing up the ones it currently has. It is typically done on a 2:1 ratio. For example, if you own 100 shares of a stock priced at $80 per share, after the split, you'll have 200 shares priced at $40 each. The number of shares changes, but the value remains the same. Stock splits occur when prices are increasing in a way that deters and disadvantages smaller investors. They can also keep the trading volume up by creating a larger buying pool to trade. If you invest in a stock, expect to experience a stock split at some point.
