Barclays Stockbrokers, the execution-only retail brokerage arm of Barclays, has launched a new structured product offering investors returns of up to four times the rise in the FTSE 100.

The UK 4x Supertracker, which has a five-and-a-half year term, offers four times the rise in the index, up to 100 per cent, meaning that if the FTSE 100 has risen by 20 per cent by the end of the product’s life investors would receive an 80 per cent return. If however the index has fallen below 60 per cent of its initial level at any point and is below the start level at maturity then capital is lost on a one-to-one basis with the index.

“This is a great product for investors who anticipate the FTSE will only provide moderate growth over the next five and a half years,” Des Byrne, managing director, head of Barclays Stockbrokers, said in a statement.

The start date of the investment is 25 October and it carries a minimum investment of £500 (almost $800).
