The fund has $2.5 million to invest, and its objective is to maximize total dollar return from both growth and dividends over the course of the coming year. The client has researched eight high-tech companies and wants the portfolio to consist of shares in these firms only. Three of the firms (51-83) are primarily software companies, three (H1-H13) are primarily hardware companies, and two (C1-C2) are Internet consulting companies. The client has stipulated that no more than 40% of the investment be allocated to any one of these three sectors. To ensure diversification, at least $100,000 must be invested in each of the eight stocks. Moreover, the number of shares invested in any stock must be a multiple of 1000 The table below gives estimates from the investment company's database relating to these stocks. These estimates include the price per share the projected annual growth rate in the share price, and the anticipated annual dividend payment per share.
