One disadvantage of using the price/sales (P/S) multiple for stock valuation is that:
A) |
profit margins are not consistent across firms within an industry. | |
B) |
P/S multiple does not provide a framework to evaluate the effects of corporate policy decisions and price changes. | |
C) |
sales are relatively stable and might not change even though earnings and value might change significantly. | |
The stability of sales (relative to earnings and book value) can be a disadvantage. For example, revenues may remain stable but earnings and book values can drop significantly due to a sharp increase in expenses. |
