An autocall that has a single (mono) underlying. It is a structured product that is linked to a single underlying asset with the ability to automatically mature or kick out prior to its maturity date if certain prespecified market conditions (triggers) have arisen and affected the underlying asset’s performance. An example of a mono-underlying autocall is an equity-linked autocallable note or bond, where the holder will automatically get an early redemption when the underlying equity (stock) trades through a specific strike level (autocall barrier) at a predetermined recalling date (observation date/ dates) or at maturity if such an event does not occur.
