Parnassus - Mid-Cap Fund

Parnassus Mid-Cap Fund

Objective:

Capital appreciation.

Strategy

The Parnassus Mid-Cap Fund is a diversified, fundamental, U.S., mid-cap, core equity fund. The Fund invests principally in undervalued equity securities of medium-capitalization companies between $3 billion and $20 billion at the time of initial purchase. The Fund seeks to invest in established companies with good businesses that are still developing. The Fund also takes environmental, social and governance factors into account in making investment decisions.

Risks

The Fund’s share price may change daily based on the value of its security holdings. Stock markets can be volatile, and stock values fluctuate in response to the asset levels of individual companies and in response to general U.S. and international market and economic conditions. Security holdings in the fund can vary significantly from broad market indexes.

The Fund invests in the stocks of mid-cap companies, which are generally riskier than larger companies, and the Fund’s share price may be more volatile than funds that invest in larger companies.

A beta over 1 suggests that the share price will typically be more volatile than the market, and conversely, a beta below 1 indicates that the share price will typically be less volatile than the market.
