Sociologist, author, and financial journalist Alfred W. Jones is credited with the creation of the first hedge fund in 1949.[4] Jones believed that price movements of an individual asset could be seen as having a component due to the overall market and a component due to the performance of the asset itself. In order to neutralise the effect of overall market movement he balanced his portfolio by buying assets whose price he expected to rise and selling short assets he expected to fall. He saw that price movements due to the overall market would be cancelled out because if the overall market rose the loss on shorted assets would be cancelled by the additional gain on assets bought and vice-versa. Because the effect is to 'hedge' that part of the risk due to overall market movements this became known as a hedge fund.
