This one is not written up yet

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

• BackwardationA market in which the futures price sits below the spot price — the cost of carry says futures should be dearer, and something is overriding it.
• BasisThe difference between the spot price and the futures price of an asset — positive when spot exceeds futures, negative when futures exceeds spot, and zero at expiry.
• 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.
• ContangoA market in which the futures price sits above the spot price, normally because the futures buyer is paying for the cost of carrying the commodity through to delivery.
• Convenience yieldThe rupee benefit of physically holding a commodity rather than holding a futures contract on it — the term that lets a futures price fall below spot plus carry.
• Daily Settlement PriceThe price at which every open futures position is marked and reset at the end of each day — the last 30 minutes' volume weighted average price of that contract, computed separately for each expiry.
