There are some important considerations when using TSR, such as: Risk. When using TSR to compare the performance of two or more companies it is important to allow for relative risk. TSR assumes efficient share pricing at the beginning and end of the period examined. The time period of examination: A TSR over a five-year period can look very different from a TSR measured over a one-year or ten-year period when examined alongside the TSR of a peer group. Please note that, using TSRs for bonuses may not always align managerial interests with shareholders. And, TSR is useless in the case of companies not quoted on a stock market.
The wealth added index (WAI) takes as its starting point the factors in TSR, i.e. capital gain or loss on shares plus dividends over a period of time, but also takes into account the time value of money by deducting the ‘cost of equity’.
WAI is measured in terms of absolute money amounts.
To calculate WAI: First, calculate the rise in market capitalisation over the period. Second, deduct the portion of that market capitalisation rise due to the firm raising more equity capital, e.g. through a rights issue. Third, add back any cash paid out to shareholders, e.g. dividends, share buy-backs. Fourth, deduct the required return on equity committed by shareholders at the start.
Considerations when using wealth added index: Doubts about the capital asset pricing model -Assumes that the stock market prices shares correctly at the beginning and end dates; There can be long periods of poor performances; Big companies appear to do best. Market Value Added (MVA) compares the market value of the firm (debt plus equity) with the total capital contributions to date (debt plus equity).
MVA is measured in terms of absolute money amounts.
If the market value of debt is assumed to be the same as the book value, then MVA will compare the market value of the equity with the total equity contributions to date (including the economic value of retained profits).
And, the following are considerations when using market value added: Doubts about the validity of the ‘capital invested figure’; When was value created? Distorted by size; Does not state if the rate of return is high enough
Excess return (ER) tries to solve two of the problems present in MVA calculations: First, it allows for the required rate of return for the period of time that the firm has held shareholders’ money. Second, it includes the dividends received by shareholders over the years since the firm’s foundation.
Excess return expressed in present value terms equals Actual wealth expressed in present value terms minus Expected wealth expressed in present value terms
Expected wealth is the current value that one should expect shareholders to have in the business given the amount of capital they put in (and retained in the business) and given the required rate of return since they put it in.
Actual wealth is the accumulated present value of the cash flows received by shareholders over the years of their investment plus the current market value of the shares.
ER is measured in terms of absolute money amounts.
The drawbacks of excess return include: The difficulty of identifying the amount of equity capital put into a business that has traded for many decades; The assumption of market pricing efficiency in ‘correctly’ pricing the company’s shares at the present time; It is difficult to state with precision what the required rate of return should be, and; Large companies dominate a ‘league table’ of ER because it is measured in absolute money amounts.
Market to book ratio, MBR = Market value divided by capital invested.
Because MBR is so similar to MVA it has similar advantages and disadvantages.
Limitations of whole-firm value metrics: They require a market valuation and thus they are useful only for the minority of corporations with a quotation and they cannot be employed to analyse a sub-section of a company (such as a strategic business unit or product line).
