The following information supplements similar information found in the "Investment Policies and Limitations" section on page 2.

Diversification

For each fund:

The fund may not with respect to 75% of the fund's total assets, purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities, or securities of other investment companies) if, as a result, (a) more than 5% of the fund's total assets would be invested in the securities of that issuer, or (b) the fund would hold more than 10% of the outstanding voting securities of that issuer.

The following information has been removed from the "Investment Policies and Limitations" section found on page 3.

Diversification

For Blue Chip Value:

In order to qualify as a "regulated investment company" under Subchapter M of the Internal Revenue Code of 1986, as amended, the fund currently intends to comply with certain diversification limits imposed by Subchapter M.

For purposes of the fund's diversification limitation discussed above, Subchapter M generally requires the fund to invest no more than 25% of its total assets in securities of any one issuer and to invest at least 50% of its total assets so that (a) no more than 5% of the fund's total assets are invested in securities of any one issuer, and (b) the fund does not hold more than 10% of the outstanding voting securities of that issuer. However, Subchapter M allows unlimited investments in cash, cash items, government securities (as defined in Subchapter M) and securities of other regulated investment companies. These tax requirements are generally applied at the end of each quarter of the fund's taxable year.

Jennifer Uhrig is the portfolio manager of Blue Chip Growth Fund and receives compensation for her services. As of November 30, 2006, portfolio manager compensation generally consists of a fixed base salary determined periodically (typically annually), a bonus, in certain cases, participation in several types of equity-based compensation plans, and, if applicable, relocation plan benefits. A portion of the portfolio manager's compensation may be deferred based on criteria established by FMR or at the election of the portfolio manager.

The portfolio manager's base salary is determined by level of responsibility and tenure at FMR or its affiliates. The primary components of the portfolio manager's bonus are based on the pre-tax investment performance of the portfolio manager's fund(s) and account(s) measured against a benchmark index and within a defined peer group assigned to each fund or account. The pre-tax investment performance of the portfolio manager's fund(s) and account(s) is weighted according to her tenure on those fund(s) and account(s) and the average asset size of those fund(s) and account(s) over her tenure. Each component is calculated separately over the portfolio manager's tenure on those fund(s) and account(s) over a measurement period that initially is contemporaneous with her tenure, but that eventually encompasses rolling periods of up to five years for the comparison to a benchmark index and rolling periods of up to three years for the comparison to a Morningstar peer group. A smaller, subjective component of the portfolio manager's bonus is based on the portfolio manager's overall contribution to management of FMR. The portion of the portfolio manager's bonus that is linked to the investment performance of Blue Chip Growth Fund is based on the fund's pre-tax investment performance measured against the Russell 1000^® Growth Index and the pre-tax investment performance of the fund within the Morningstar^® Large Cap Growth Category. The portfolio manager also is compensated under equity-based compensation plans linked to increases or decreases in the net asset value of the stock of FMR Corp., FMR's parent company. FMR Corp. is a diverse financial services company engaged in various activities that include fund management, brokerage, retirement, and employer administrative services. If requested to relocate their primary residence, portfolio managers also may be eligible to receive benefits, such as home sale assistance and payment of certain moving expenses, under relocation plans for most full-time employees of FMR Corp. and its affiliates.

The portfolio manager's compensation plan may give rise to potential conflicts of interest. Although investors in a fund may invest through either tax-deferred accounts or taxable accounts, a portfolio manager's compensation is linked to the pre-tax performance of the fund, rather than its after-tax performance. The portfolio manager's base pay tends to increase with additional and more complex responsibilities that include increased assets under management and a portion of the bonus relates to marketing efforts, which together indirectly link compensation to sales. When a portfolio manager takes over a fund or an account, the time period over which performance is measured may be adjusted to provide a transition period in which to assess the portfolio. The management of multiple funds and accounts (including proprietary accounts) may give rise to potential conflicts of interest if the funds and accounts have different objectives, benchmarks, time horizons, and fees as a portfolio manager must allocate her time and investment ideas across multiple funds and accounts. In addition, a fund's trade allocation policies and procedures may give rise to conflicts of interest if the fund's orders do not get fully executed due to being aggregated with those of other accounts managed by FMR or an affiliate. The portfolio manager may execute transactions for another fund or account that may adversely impact the value of securities held by a fund. Securities selected for other funds or accounts may outperform the securities selected for the fund. Portfolio managers may be permitted to invest in the funds they manage, even if a fund is closed to new investors. Trading in personal accounts, which may give rise to potential conflicts of interest, is restricted by a fund's Code of Ethics.
