A hedger describes a financialinvestors who take up opposing positions in order to reduce risk. For example, a fund manager may invest in a portfolio of leading shares from the London Stock Exchange. If the market as a whole goes down, this portfolio will suffer even though the companies selected may be good.
This profit can be used to offset the losses in the portfolio, while the fund manager takes the profit or loss relating from the difference between the market's performance (captured by the hedging position) and that of the portfolio. This figure is similar to the fund's beta, or performance relative to the general market.
