ETF Research Center Fund Rating
The ALTAR Score™ is our measure of an ETF's overall investment merit. For fixed income funds, the Score is an estimate of risk-adjusted yield to maturity (calculation shown below). In effecient markets, the plot of ALTAR Scores™ vs. Duration should resemble the familiar yield curve. Funds that sit above the curve may offer better risk-adjusted returns than those that sit below the curve.
