The third step to avoid valuation pitfalls is to apply sound and realistic assumptions for the valuation. Assumptions are the key drivers of the valuation, and they should be based on reliable and relevant data, analysis, and judgment. For example, when using DCF, you should carefully estimate the future cash flows, growth rate, discount rate, and terminal value of the company, taking into account its financial performance, industry trends, competitive position, and recovery potential. When using multiples, you should carefully select the comparable companies or transactions, adjust for differences in size, profitability, risk, and growth, and use a range of multiples to capture the variability of the market. When using asset-based methods, you should carefully value the assets and liabilities of the company, consider the costs and timing of liquidation or sale, and account for any contingent or hidden items. You should also test the sensitivity of the valuation to different scenarios and assumptions, and explain the rationale and sources of your assumptions.
