Investment oriented calculations

As previously noted, the Turner's have some of their investment portfolio in conservative stocks. These equities have had very slow growth while regularly paying a small dividend.
Jenny and Jeff have received several emails recently with suggestions about various biotechnology, retailing, and environmental companies. The investment advisers believe that these industries would provide an opportunity for strong long-term financial gains.
In recent years, the Turners have made extensive use of mutual funds in their investment portfolio. However, they are concerned that their selection of the funds may not be coordinated. With over 9,200 different mutual funds available, this financial marketplace is confusing.
The Turner begins the evaluation process by connecting various types of mutual funds to their investments goals. Next, they assess the past performance and management of the funds. Finally, they talk with various financial advisers and other investors to gather additional information.
