Question

What are the major limitations of equity valuation using multiples such as P/E or P/B?

Answer 1

The price-to-earnings ratio (P/E ratio) is the ratio for valuing a company that measures its current share price relative to its per-share earnings (EPS). The price-to-earnings ratio is also sometimes known as the price multiple or the earnings multiple.

P/E ratios are used by investors and analysts to determine the relative value of a company's shares in an apples-to-apples comparison. It can also be used to compare a company against its own historical record or to compare aggregate markets against one another or over time.

• The price-earnings ratio (P/E ratio) relates a company's share price to its earnings per share.
• A high P/E ratio could mean that a company's stock is over-valued, or else that investors are expecting high growth rates in the future.
• Companies that have no earnings or that are losing money do not have a P/E ratio since there is nothing to put in the denominator.
• Two kinds of P/E ratios - forward and trailing P/E - are used in practice.

The price-to-earnings ratio or P/E is one of the most widely-used stock analysis tools used by investors and analysts for determining stock valuation. In addition to showing whether a company's stock price is overvalued or undervalued, the P/E can reveal how a stock's valuation compares to its industry group or a benchmark like the S&P 500 Index.

In essence, the price-to-earnings ratio indicates the dollar amount an investor can expect to invest in a company in order to receive one dollar of that company’s earnings. This is why the P/E is sometimes referred to as the price multiple because it shows how much investors are willing to pay per dollar of earnings. If a company was currently trading at a P/E multiple of 20x, the interpretation is that an investor is willing to pay $20 for $1 of current earnings.

The P/E ratio helps investors determine the market value of a stock as compared to the company's earnings. In short, the P/E ratio shows what the market is willing to pay today for a stock based on its past or future earnings. A high P/E could mean that a stock's price is high relative to earnings and possibly overvalued. Conversely, a low P/E might indicate that the current stock price is low relative to earnings.
