How can an investor benefit from a predicted rise or predicted fall in the price of a stock ?
An investor can benefit from a predicted rise in the price of a stock by buying futures. As the price of the futures rises, the investor will make a positive return. As the investor will have to pay only the margin (which forms a fraction of the notional value of contract), his return on investment will be higher than on an equivalent purchase of shares. An investor can benefit from a predicted fall in the price of stock by selling futures. As the price of the future falls in line with the underlying stock, the investor will make a positive return.
