Risks Associated with Conservative to Moderate Funds

Vanguard funds classified as moderate to conservative are subject to low-to-moderate fluctuations in share prices. In general, such funds are appropriate for investors with medium-term investment horizons (four to ten years), for those seeking an investment that emphasizes income rather than growth, and for investors who have a low tolerance for the risk of short-term price fluctuations.

Plain Talk About Risk

The portfolio’s share price and total return will fluctuate, along with returns for the overall high yield bond market, within a wide range, so an investor could lose money over short or even long periods. The portfolio’s underlying fund is also subject to:

  • Interest rate risk. This is the risk that the value of bonds held by an underlying fund will decline because of rising interest rates. Interest rate risk is higher for long-term bond funds and lower for short-term bond funds.
  • Income risk. This is the risk that falling interest rates will cause an underlying fund’s income to decline. Income risk is generally higher for short-term bond funds and lower for long-term bond funds.
  • Call/prepayment risk. This is the risk that during periods of falling interest rates, issuers will call—or repay—higher-yielding bonds that are callable before their maturity dates. The underlying fund would lose potential price appreciation and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund’s income. For mortgage-backed securities, this risk is known as prepayment risk.
  • Credit risk. This is the risk that an issuer of a bond owned by an underlying fund will default by failing to make timely payments of principal and interest.
  • Manager risk. This is the risk that poor security selection will cause an underlying fund to underperform other funds with a similar investment objective. There is no guarantee that the investment techniques and risk analyses used by the managers will produce the desired results.
  • Derivatives risk. Each of the underlying funds in which the portfolio invests may, to a limited extent, invest in derivatives, which may involve risks different from, and possibly greater than, those of traditional investments. To help stay fully invested, and to reduce transaction costs, the funds may invest in stock futures and options contracts, warrants, convertible securities, and swap agreements, which are types of derivatives. The underlying funds will not use derivatives for speculative purposes or as leveraged investments that magnify gains or losses.
  • Index sampling risk. This is the risk that the securities owned by an underlying fund that uses the sampling method of indexing will not provide investment performance matching that of the fund’s target index.

Please note: Before investing in any 529 plan, you should consider whether your or the beneficiary's home state offers a 529 plan that provides its taxpayers with favorable state tax and other benefits that are only available through investment in the home state's 529 plan. You also should consult your financial, tax, or other adviser to learn more about how state-based benefits (or any limitations) would apply to your specific circumstances. You also may wish to contact directly your home state's 529 plan[s], or any other 529 plan, to learn more about those plans' features, benefits, and limitations. Keep in mind that state-based benefits should be one of many appropriately weighted factors to be considered when making an investment decision.
