Wall Street is flogging structured investments to retail clients in an attempt to capture more business and fees, according to a largely skeptical article in the June 21 issue of the Wall Street Journal. These complex investments combine different types of instruments, say a zero-coupon bond and a stock index option, and offer some degree of principle protection. However, they charge high fees and their payoff potential is difficult to model. Of the 1,400 structured products available in the United States, nearly 650 were launched in the last year, the article states.
