In
finance, a hedge is an investment that is taken out specifically to reduce or cancel out the
risk in another investment. Hedging is a
strategy designed to minimize exposure to an unwanted business risk, while still allowing the business to profit from an investment activity. Typically, a hedger might invest in a
security that he believes is under-priced relative to its "fair value" (for example a mortgage loan that he is then making), and combine this with a
short sale of a related security or securities. Thus the hedger is indifferent to the movements of the market as a whole, and is interested only in the performance of the 'under-priced' security relative to the hedge.
Holbrook Working, a pioneer in hedging theory, called this strategy "speculation in the basis,"
[1] where the basis is the difference between the hedge's theoretical value and its actual value (or between spot and
futures prices in Working's time).
