The definition above is the short version. A full explanation — how it works, a worked example and the exam traps — is still being written. In the meantime the chapter below covers it in context.

Written up from the same chapter

• Bollinger bandsA technical indicator that plots bands a set number of standard deviations either side of a moving average, treating prices at the upper band as overbought and at the lower band as oversold.
• Corporate governanceThe rules, processes and procedures followed in running a company, judged by an analyst against a checklist of board, audit and related-party tests rather than by reputation.
• Discounted Cash FlowA valuation method that estimates the cash a business will generate in future years and converts each year back to what it is worth today.
• Earnings yieldEarnings per share divided by the current market price — the reciprocal of the P/E ratio, expressed as a percentage so that equity can be set directly against a bond yield.
• Economic Value AddedA company's after-tax operating profit less a charge for the capital employed to earn it — the profit that remains after the providers of capital have been paid what they required.
• Enterprise ValueWhat it would cost to buy the whole business — market capitalisation plus debt, less cash — as opposed to market capitalisation, which buys only the equity.
