While evaluating a prospective investment, there are three factors that you MUST look at: risk, cash flow, and resale value.
The first factor to be evaluated in any investment analysis is risk. The reason for this is simple: if the risk of the investment is too great then loss is quite likely. In this case, cash flows and resale value generally do not matter because the investment is worth nothing. To evaluate risk, one simply uses a variation of the following general formula:
Probability of an Event occurrence * the Impact of the event = Risk
The second factor of investment analysis is cash flows. Cash flows may have source from dividends from a publicly traded stock, interest payments on a bond, free cash flow distributed to the investors in a small business, etc. Cash flows are the main source of repayment on an investment. Thus, an investor will want to evaluate cash flows to see if they can repay the investment while also repaying the assumed value of the risk on the investment. Two of the most general methods of evaluating cash flows are Future Value of Cash Flows and Discounted Cash Flow Analysis – they work almost everywhere. Each investor may use a method of analysis based on the type of investment they are considering (mentioned above). The tool which definitely helps here is a relevant Financial Model for the investment under review. Regardless, ignoring the analysis of cash flows is a quick path to loss of investment capital.
