This type falls in the category of structured products with leverage.
Its name speaks for itself – it resembles futures. There are futures for purchase and for sale. The first one gives income when the underlying asset price grows, the second – when it falls. The income on mini-futures grows due to the multiplier embedded into this product. If the multiplier is 4, when the price changes by 1%, the income changes by 4%. This type has a stop-loss to prevent big debts of the investor if the price moves unfavourably. When the stop-loss level is reached, the investor is paid the remaining value.
