This paper developed long-term investment of stock cash flow activities comprising of how yearly investment contribution turns to share units and vice versa, how the series of dividends pay out are declared and finally, how the growth of share units are generated over the years of investing period. These investment model activities form cash inflows and outflows and hence, in return, the performance of this investment model can be evaluated. In addition, this model also constrained that, the yearly dividends obtained were being reinvested together with the annual contributions in accumulating shares. Besides presenting the computation of purchasing and selling of share units and the amount of dividend obtained, this paper contributed in the computation of the growth of the shares in a year, based on share issuance such as share split or consolidation, as well as bonus share rewards. Based on these activities, the net present value (NPV) was derived and the modified internal rate of return (MIRR) was determined by setting up zero-valued of NPV. We illustrated the computation of MIRR by looking at the investment activity towards Prolexus Berhad from the year 2011 to 2015. The increasing of company share prices through years, the encouraging series of dividend rates and generous of the company in issuing shares to the shareholders, were also clearly figured that determined attractive MIRR.
