2024 muni bond supply is projected to decline 5%, increasing appeal for retail holders investing in bond funds with tax-exempt income potential. When looking at a fund's performance, it is also important to note the standard deviation of the returns. The lower the standard deviation, the less volatility the fund experiences. Over the past three years, ACTHX's standard deviation comes in at 9.31%, compared to the category average of 12.76%. Looking at the past 5 years, the fund's standard deviation is 8.45% compared to the category average of 12.2%. This makes the fund less volatile than its peers over the past half-decade. Yield to maturity (YTM) represents the expected total return on a bond (expressed as an annualized rate) based on the bondâs expected future cash flows, including coupon payments over the life of the bond and the bondâs principal value received at maturity. Recent downgrade risks in cyclical equities redirect pension fund allocations. Investing in bond funds becomes a strategic risk mitigation measure.
