Strategy Narrative [Text Block]
The Fund is considered non-diversified, which means it can invest a higher percentage of assets in securities of individual issuers than a diversified fund. As a result, changes in the value of a single investment could cause greater fluctuations in the Fund's share price than would occur in a more diversified fund.
