Index arbitrage

An investment trading strategy that exploits divergences between actual and theoretical futures prices. An example is the simultaneous buying (selling) of stock index futures (i.e., S&P 500) while selling (buying) the underlying stocks of that index, capturing as profit the temporarily inflated basis between these two baskets. Often, the point at which profitability exists is expressed at the block call as the number of points the future must be over or under the underlying basket for an arbitrage opportunity to exist. See: Program trading.

Index Arbitrage

A form of arbitrage in which an investor takes advantage of discrepancies in price between a stock index and a futures contract on that index. Index arbitrage occurs when an arbitrageur takes one position on a stock index (or on the individual stocks underlying the index) while taking an equal but opposite position on a futures contract on the index. He/she is then able to profit from the difference in the price between the two.
