    What Is the Justified Price to Earnings Ratio?

Market analysts and investors regularly employ this variant of the conventional P/E statistic, which is frequently abbreviated to justified P/E ratio or simply justified P/E.

    What Does Justified P/E Ratio Indicate?

    Many market experts view a justifiable P/E ratio that is nearly comparable to the firm’s forward P/E ratio as proof that the company’s stock is properly valued, taking into account past price movements, the cost of equity, and the company’s predicted current and future growth rates.

    The stock is most likely undervalued or underpriced if the justified P/E is higher than the forward P/E. Alternatively, if all other factors are equal and the justified P/E is lower than the firm’s projected P/E, the stock is regarded as being overvalued at the current price.

    What Are the Advantages and Disadvantages of a Justified P/E Ratio?

    The justified P/E ratio’s greatest benefit is that it demonstrates how the P/E is connected to the company’s fundamentals. It provides information on the anticipated dividend payout ratio, the necessary rate of return, and the anticipated dividend growth rate.

    Its vulnerability to inputs, like the Gordon Growth model, is one of its drawbacks. As a result, analysts will typically calculate a range of values for various inputs in practice.

    Example of Calculating a Justified P/E Ratio

    Let’s say that Company X has a net income of $1,860,000. 

    The number of shares that are trading are 1,000,000 at a price of $30 each. The earnings per share are $1.86 and the dividends per share sit at 0.80.

    This would give a price-to-earnings ratio of 16.13. 

    Now, with this information, we can figure out the justified price-to-earnings ratio. 

    The cost of equity of Company X is 8%, with a forward growth rate of 5.4%. Using all of this information and inputting it into the above formula would give us a justified price-to-earnings ratio of 17.44. This would mean that the share price of Company X is currently underpriced. 


    The Gordon Growth Model-related price-to-earnings ratio has a variant called the Justified P/E Ratio (GGM).

    Connecting the conventional P/E ratio to the Gordon Growth Model yields the justified price-to-earnings ratio (GGM).

    The P/E ratio evaluates a company’s common stock shares at their current market value in relation to its earnings. By using the justified P/E, you can learn more about a company’s true performance.
