The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund.

Non-Diversified Fund Risk.  The Fund is classified as non-diversified.  As such, the percentage of the Fund’s assets invested in any single issuer, or a few issuers is not limited as much as it is for a Fund classified as diversified.  Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.
