Short selling refers to the practice of borrowing an asset to sell today in exchange for cash, with the expectation that its price falls during the investment period before repurchasing the asset and returning it to the owner. Short selling can be undertaken for various reasons, including to hedge specific sector risks or to manage a fund’s total market exposure. Short sales create leverage or gearing for the underlying fund, thereby amplifying investment performance.
Leverage is the use of various financial instruments or borrowed capital, such as margin, to increase the potential return of an investment. Higher leverage can amplify investment returns, both on the upside and downside. Leverage includes the use of derivatives. Derivatives derive their value from the value of an underlying asset. The degree to which leverage may be employed within a hedge fund is limited by the investment mandate.
Volatility, also known as the standard deviation of the fund’s return, is a measure of how much a fund’s return varies from its average over time
Alpha is a term used in investing to describe a portfolio’s ability to beat the market return over some period of time. Alpha is often referred to as the “excess return” or “active return” on an investment and gauges the performance of an investment against a market index or benchmark that is considered to represent the market’s movement as a whole.
