F/m?Investments Launches First 30-Year TIPS ETF:?RTHY
Business Wire (Tue, 20-Oct 9:00 AM ET)
The F/m Ultrashort TIPS Fund is a passively-managed exchange-traded fund ("ETF") that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the Bloomberg U.S. Ultrashort TIPS 1-13 Months Total Return Unhedged USD Index (I39232US) ("Underlying Index"), which measures the performance of U.S. Treasury InflationProtected Securities ("TIPS") with maturities from 1 month up to (but not including) 13 months. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the non-seasonally adjusted Consumer Price Index for All Urban Consumers ("CPI-U"), and TIPS' principal payments are adjusted according to changes in the CPI-U. A fixed coupon rate is applied to the inflation-adjusted principal so that, as inflation rises, both the principal value and the interest payments increase. Under normal market conditions, F/m Investments LLC (the "Adviser") seeks to achieve the Fund's investment objective by investing at least 80% of the Fund's net assets (plus any borrowings for investment purposes) in TIPS with maturities of 1-13 months.
