INDEX FUND

PROSPECTUS

   The following information replaces similar information found in the
"Fee Table" section on page 4.

   The combined total expense ratio of Four-in-One Index (calculated
as a percentage of average net assets) is estimated to be 0.32%.
Four-in-One Index's estimated combined total expense ratio is based on
its estimated total operating expense ratio plus a weighted average of
the total operating expense ratios, after expense reductions, of the
underlying Fidelity funds in which it would have been invested (for
each underlying Fidelity fund's most recently reported fiscal year) as
of June 26, 1999. The combined total expense ratio for Four-in-One
Index may be higher or lower depending on the allocation of the fund's
assets among the underlying Fidelity funds and the actual expenses of
the underlying Fidelity funds.

   This     EXAMPLE    helps you compare the cost of investing in
Four-in-One Index with the cost of investing in other mutual
funds.

   Let's say, hypothetically, that Four-in-One Index's annual return
is 5%, that your shareholder fees are exactly as described in the fee
table, and that Four-in-One Index's combined total expense ratio
includes Four-in-One Index's annual operating expenses exactly as
described in the fee table and the weighted average of the total
operating expenses of each of the underlying Fidelity funds, before
expense reductions. This example illustrates the effect of fees and
expenses, but is not meant to suggest actual or expected fees and
expenses or returns, all of which may vary. For every $10,000 you
invested, here's how much you would pay in total expenses if you close
your account after the number of years indicated:

1 year   $ 67

3 years  $ 211
