1 OBJECTIVE
Vanguard Explorer Fund seeks to provide long-term capital growth. The Fund may
not meet this objective.
2 INVESTMENT STRATEGY
The Fund invests in stocks of small companies (that is, those with an average
market value of less than $1 billion). These companies tend to be unseasoned but
are considered to have favorable prospects for growth. In addition to investing
in common stocks, the Fund may also invest, to a limited degree, in short-term
fixed-income securities, and futures and options contracts.
3 RISKS
The Fund's total return will fluctuate, so an investor could lose money over
short or extended periods. More specifically, investors in the Fund are exposed
to . . .
- - A HIGH degree of stock market risk (the possibility that stock prices
in general will decline over short or extended periods).
Historical returns for the U.S. stock market (as measured by the Standard &
Poor's 500 Composite Stock Price Index) show some of this market volatility.
From 1926 to 1996, the S&P 500 Index provided an annualized total return of
10.7%, but provided a negative return--averaging -12.3%--in 20 of these 71
years. Annual returns for the period ranged from a low of -43.3% to a high of
53.9%.
Because it emphasizes the stocks of smaller companies, the Fund is likely to
perform differently than broader market benchmarks like the S&P 500 Index.
4 APPROPRIATENESS
This Fund may be suitable for investors who . . .
- - Are seeking long-term capital growth.
- - Are willing to assume above-average investment risk.
- - Want an aggressive growth fund as part of a balanced investment program.
- - Plan to invest for at least five years.
The Fund is not suitable for investors who . . .
- - Are seeking current income.
- - Cannot tolerate fluctuating share prices.

Note: In evaluating past performance, it is important to consider that returns
from stocks were close to their highest levels in history during the past ten
years. Past performance is not indicative of future performance.
Performance figures include the reinvestment of all dividends and any capital
gains distributions. All returns are net of expenses. The performance data
quoted represent past performance. The investment return and principal value of
an investment will fluctuate so that investors' shares, when redeemed, may be
worth more or less than their original cost.
