What does VIPSX invest in?

This fund is designed to safeguard investors' capital from the eroding effect of inflation by primarily investing in securities structured to provide a "real" return. It focuses specifically on government-backed, inflation-indexed bonds, where the principal value is periodically adjusted in response to inflationary changes. The portfolio entails moderate to significant interest rate risk, meaning fluctuations in market interest rates, whether upward or downward, could lead to diminished bond prices or a future reduction in income. Additionally, the income generated by the fund may exhibit greater volatility than typical bond investments, as its payments are directly tied to evolving inflation rates. Long-term investors may find this fund a suitable addition to an existing, diversified fixed-income portfolio.
