The GNMA Fund can be an attractive option for income investors who are willing to tolerate some price volatility. Unlike corporate bond funds, the GNMA Fund has negligible credit risk since it invests only in securities guaranteed by the U.S. government. Mortgage-backed bonds offer higher income than Treasuries without any decrease in credit quality.
Yield and share price will vary with interest rate changes. Investors should note that if interest rates rise significantly from current levels, bond fund total returns will decline and may even turn negative in the short term. The fund is also susceptible to prepayment risk, which occurs when homeowners pay off their loans early. Your investment in the fund is not insured or guaranteed by the U.S. government.
**This chart displays relative risk of each U.S. mutual fund listed using standard deviation of returns. Those values are provided in the bars at the top of the chart.
Methodology: We evaluate the standard deviation and its resulting placement within a specific risk/return category on an annual basis. A fund is generally placed in a risk/return category based on the 10-year standard deviation of its performance.
If a fund is less than 10 years old, the actual fund performance history is supplemented with the primary prospectus benchmark history to obtain a full 10-year history, or longest time period available up to 10 years.
For an Asset Allocation fund with less than 10 years of performance history, sub-strategy returns are used.
When a sub-strategy is less than 10 years old, the actual sub-strategy performance history is supplemented with benchmark history to obtain a full 10-year history, or longest time period available up to 10 years.
Risk return categories overlap; a fund with a standard deviation in the overlap between two categories, denoted by a plus (+), is placed so that its risk categorization is better aligned with anticipated return characteristics an investor may experience going forward at the discretion of T Rowe Price.
When a fund has a cash-like benchmark, denoted by a double plus (++), its standard deviation is estimated using only available fund returns. If the fund is less than 10 years old, benchmark returns are not used to obtain a full 10-year history because they would artificially suppress the volatility estimate.
All investments are subject to market risk, including the possible loss of principal. Standard deviation of returns, a measure of price volatility, is one measure of risk. Please consult the funds' prospectuses for a more complete discussion of the funds' risks.
