Greenblatt's Magic Formula Investing: Financial News - Yahoo! Finance: "What makes Greenblatt's message valuable is its focus on investing as opposed to speculating. Investing involves risk, but it is not buying something with the hope that you'll be able to sell it to someone else for a greater price later. Investing is financing the operations of a business, and it involves trying to understand if that business is healthy enough and profitable enough to give you an adequate return on your capital from its operations, based on the price you've paid for your interest in those operations."
