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

• BetaHow sharply a share moves relative to the market index — beta 1 moves with the index, above 1 amplifies it, below 1 dampens it. The standard measure of systematic risk.
• Business riskThe variability of a firm's income flows caused by the nature of its business — driven by how volatile its sales are and how much of its cost base is fixed.
• CAGRThe single smoothed annual rate at which a starting value would have to grow, compounding each year, to reach the ending value over a given period.
• Credit riskThe risk that a borrower fails to meet its obligations on a debt instrument — the risk credit rating agencies exist to grade, and the one that triggers a segregated portfolio in a mutual fund.
• Holding period returnThe total of coupons, income earned on reinvesting them and any capital gain, expressed as a percentage of the purchase price — a crude return for the period actually held, with no compounding in it.
• Inflation riskThe risk that the money an investment pays out will be worth less in goods and services than expected, because prices have risen — highest in fixed-return products and most damaging to retirees.
