Yield to maturity (YTM) does not represent return. YTM provides a summary measurement of an investment’s cash flows, including principal received at maturity based on a given price. Actual yields may fluctuate due to a number of factors such as the holding period, changes in reinvestment rates as cash flows are received and redeployed, receipt of timely income and principal payments. DoubleLine views YTM as a characteristic of a portfolio of holdings often used, along with other risk measures such as duration and spread, to determine the relative attractiveness of an investment.
