Delta One products are a class of financial derivative that have no optionality and as such have a delta of (or very close to) one - that is to say that for a given percentage move in the price of the underlying asset there will be a nearly identical move in the price of the derivative. Delta one products often incorporate a number of underlying securities and as such give the holder an easy way to gain exposure to a basket of securities in a single product. Examples include equity swaps, forwards, futures and ETFs.
The delta measures the sensitivity of a derivative's value to changes in the price of the underlying asset. The delta (Δ) of an instrument is the first mathematical derivative of the option value with respect to the underlier's price.
Types of products
It is a derivative with a linear, symmetric payoff profile. That is, not an option or a product with embedded options. Examples of delta one products are Exchange-traded funds, equity swaps, custom baskets, linear certificates, futures, forwards, exchange-traded notes, trackers, and Forward rate agreements. As the price for these products closely track their underlying asset and risk free rate, their delta will be close to 1.
Delta One trading desks are either part of the equity finance or equity derivatives divisions of most major investment banks. They generate most revenue through a variety of strategies related to the various delta one products as well as related activities, such as dividend trading, equity financing and equity index arbitrage. In theory such desks should be relatively low risk areas for the banks as the products are generally hedged. FT Alphaville has described Delta One trading as "one of the hottest areas in banking" and "...the last domain of prop trading in the banking sector, where via market-making activities, traders can still get away with taking ample risks."
