Municipal Over Bond (MOB)

Spread measures the relative difference between the municipal bond index future price and the U.S. Treasury bond futures price.

Remarks: Bond funds including mutual funds (open-end and closed-end, actively managed and indexed), exchange-traded funds and unit investment trusts offer a convenient and affordable way to invest in a diversified portfolio of bonds, but a bond fund investment can differ from a bond investment in ways that are important to understand.
