Mutual Fund · Currency in USD · Last updated Jun 3, 2026

The investment seeks to provide long-term capital growth. The fund will normally invest at least 80% of its net assets (including any borrowings for investment purposes) in securities of communications and technology companies. The portfolio manager may use both growth and value approaches to stock selection. The fund's portfolio may hold stocks of either U.S. or non-U.S. companies, and may at times consist of a relatively small number of holdings. It is non-diversified.

PRMTX's Sharpe Ratio of 0.37 indicates that for each unit of volatility, it generates 0.37 units of excess return above the risk-free rate. The ratio is calculated using historical daily returns over the past 12 months (as of Jun 3, 2026).

Sharpe uses total volatility (standard deviation) which includes both upside and downside price movements, making it useful for comparing risk-adjusted returns across different assets.
