Advantages of the ratios are as follows:
PricetoEarnings (P/E)
 Easy to use
 Most commonly used measure of valuation
 Studies have indicated a strong correlation to longterm returns.
PricetoBook Value (P/BV)
 Tends to be a stable valuations metric because balance sheets do not fluctuate much quartertoquarter.
 Can be used as a valuation metric even when firms report an EPS loss.
 Good metric to value firms in distress
PricetoSales (P/S)
 Sales tend to be a realistic number and are not influenced as heavily by accounting issues.
 Good metric to value firms in distress.
 Can be used as a valuation metric when firms report a loss.
Priceto Cash Flow (P/CF)
 Cash flow is a truer metric of a company's results in comparison to earnings.
 It is more difficult for managements to manipulate cash flow  tends to be less volatile than earnings.
 Studies have indicated that it is a reliable metric over the longerterm.
Drawbacks for each multiple are as follows:
PricetoEarnings (P/E)
 Cannot be used for firms when they report a loss in earnings.
 Earnings can be volatile given various inputs.
 Earnings are more easily manipulated by managements.
PricetoBook Value (P/BV)
 Does not take into account the relative asset size when comparing firms.
 Accounting metrics can skew the results.
 Book value is not an accurate measure of actual market value.
PricetoSales (P/S)
 Sales do not always translate to profits which can leave out the cost component.
 Difficult to value companies with different cost structures.
 Accounting issues related to revenue recognition can still alter sales.
Priceto Cash Flow (P/CF)
 Some items are not included, such as noncash revenue.
