Neither ratio is universally "better"; the P/E ratio is superior for evaluating profitability and growth in stable, earnings-driven companies. The P/B ratio is better for assessing asset-heavy industries (banking, manufacturing) and companies with negative earnings. Using both together provides the most comprehensive valuation.
He has recognized that the P/E ratio and book value are simply too crude to use directly as value indicators, particularly when he is able to calculate an actual intrinsic value for a share. Using the P/E ratio is like trying to estimate the weight of a person by looking at their shadow.
A low P/B ratio indicates that a stock is undervalued compared to its book value and may rise in price in the future. On the other hand, a high P/B ratio indicates that the stock is overvalued, and it may be time to book profits or sell.
There's no single "good" P/E ratio, as it depends on industry, market, and growth prospects; generally, a lower P/E (like below 15-20) suggests undervaluation or slow growth, while a higher P/E (above 25-30) implies high growth expectations (typical for tech/growth stocks), but can signal overvaluation, with averages often around 20-25 for broad markets, making comparison to peers and historical trends crucial.
For example, suppose a company has Rs 150 as its Market Value (MV) per share and Rs 100 as its Book Value (BV) per share, then the price-to-book value ratio would be 150/100=1.5. This indicates that for every net asset worth Rs 1, the market is willing to pay Rs 1.5.
The market value of equity is typically higher than the book value of a company's stock. The price-to-book ratio is used by value investors to identify potential investments. P/B ratios under 1.0 are typically considered solid investments by value investors. A good P/B ratio is relative to a business and its industry.
Amazon PE ratio as of January 19, 2026 is 33.77.
The price to earnings ratio is calculated by taking the latest closing price and dividing it by the most recent earnings per share (EPS) number. The PE ratio is a simple way to assess whether a stock is over or under valued and is the most widely used valuation measure.
There's no single "ideal" P/E ratio, as it depends heavily on the industry, market conditions, and company growth, but generally, a lower P/E (like 10-20) suggests better value while a higher P/E (25+) implies high growth expectations, though it could mean overvaluation; investors compare a stock's P/E to its peers and historical averages to determine if it's cheap or expensive. Value investors often look for lower ratios, but high-growth tech companies naturally have higher P/Es, so comparing within the same sector is crucial.
A low ratio (less than 1) could indicate that the stock is undervalued (i.e. a bad investment), and a higher ratio (greater than 1) could mean the stock is overvalued (i.e. it has performed well).
Conventionally, a PB ratio of below 1.0, is considered indicative of an undervalued stock. Some value investors and financial analysts also consider any value under 3.0 as a good PB ratio. However, the standard for "good PB value" varies across industries.

As of January 2026, Coca-Cola's (KO) P/E ratio is around 23.3, while Coca-Cola Bottling (COKE) is slightly higher at approximately 23.2-23.23, indicating how much investors pay for each dollar of earnings, with KO's lower than its 12-month average but still reflecting expectations for future growth. These figures can vary slightly depending on the source and exact timing, but generally hover in the low 20s for KO and slightly higher for COKE, with KO's valuation trending down from its recent average.
Tesla's P/E ratio is high because investors price in massive future growth from its AI, robotics (Optimus), and robotaxi ventures, viewing it as a tech/growth stock rather than just an automaker, despite current EV sales pressures and intense competition. The premium reflects belief in future dominance in autonomous driving and AI, valuing these potential trillion-dollar markets alongside its existing (though challenged) EV business, leading to a valuation far exceeding traditional car companies.
