Investors are keeping a rally in the high-yield bond market going, as it remains on track to record another double-digit gain this quarter. In the past three months, speculative-grade corporate bonds have seen returns of nearly 16%, according to a Merrill Lynch index. "We're not raging bulls, but we're still bullish on this market," said Sean Slein of Dwight Asset Management. "Consumers are going to retrench and delever, so trend economic growth is going to be lower than we've experienced through previous economic cycles. In that environment, high-yield bonds do very well."
