What this fund is
Objective, as filed

Fidelity Series Growth Company Fund seeks capital appreciation.

Strategy, summarised

The fund invests at least 80% of assets in common stocks of growth companies, which the adviser identifies through fundamental analysis using criteria such as above-median earnings or sales growth, elevated research and development spending relative to administrative costs, or capital-raising activity. The fund holds both domestic and foreign securities. Because security selection depends on the adviser's assessment of individual companies' growth characteristics, fund holdings will differ from any benchmark.
