Business Description
The firm's advisory business includes investment supervisory services, also known as asset management services. They assist clients in determining investment objectives and monitor accounts daily. The firm does not accept commissions or finder's fees and is not affiliated with entities that sell financial products or securities.
The firm does not act as a custodian of client assets; clients maintain asset control. Trades are placed under a limited power of attorney. Other professionals like lawyers and accountants are engaged directly by the client as needed. Conflicts of interest will be disclosed if they occur. Peter E. Grassi is a Managing Member and Chief Compliance Officer.
Investment Strategy
For equity portfolios, Grassi Investment Management employs a "bottom up" investment strategy that focuses on fundamental analysis and research. This strategy seeks to identify specific companies that have both value and growth potential. For fixed income portfolios, the focus is on the total rate of return, which is pursued by purchasing debt securities with staggered maturities to capitalize on fluctuating interest rates.
The firm may implement investment recommendations using mutual funds. Clients should note that as mutual fund shareholders, they will bear a proportionate share of the fund's management and administrative fees, as well as sales charges, in addition to Grassi Investment Management's fees. Detailed information regarding fund expenses and fees can be found in each fund's prospectus.
