    <rr:PerformanceTableNarrativeTextBlock contextRef="S000007496_D1231FidelityTrendFundPRO09Member">         After-tax returns are calculated using the historical highest individual federal marginal income tax rates, but do not reflect
               the impact of state or local taxes.  Actual after-tax returns may differ depending on your individual circumstances. The after-tax returns shown are not relevant if you hold your shares in a retirement account or in another tax-deferred arrangement,
               such as an employee benefit plan (profit sharing, 401(k), or 403(b) plan).  Return After Taxes on Distributions and Sale of Fund Shares may be higher than other returns for the same period due to a
               tax benefit of realizing a capital loss upon the sale of fund shares.
