Which of the following is NOT a type of exchange traded structured product?

Investment-grade bonds do not fall under the category of exchange traded structured products. Instead, they are a distinct type of fixed-income security issued by corporations or governments that have a high credit rating, reflecting lower risk to investors. These bonds provide regular interest payments and the return of principal at maturity, and they are typically not structured products.

In contrast, the other options—accelerated trackers and boosters, structured capital at risk products (SCARPs), and capital protected trackers—are all examples of structured products that are designed with specific investment strategies in mind. Accelerated trackers and boosters aim to amplify returns based on the performance of an underlying asset, while SCARPs often involve some level of risk to capital in exchange for the potential of higher returns over a defined period. Capital protected trackers are designed to offer protection on the initial investment while allowing the investor to participate in market gains. These products are effectively customized investments that can cater to variations in market conditions and investor appetites, which distinctly differentiates them from standard investment-grade bonds.
