====== Price-to-Book ======
The Price-to-Book ratio (also known as the 'P/B Ratio' or 'Price-to-Equity Ratio') is a classic valuation metric that compares a company's stock market price to its net asset value. Think of it this way: if you were to buy a company, liquidate all its assets (factories, cash, inventory), and pay off all its debts, what would be left? That remainder is the company's `[[Book Value]]`. The P/B ratio tells you how much you're paying in the stock market for each dollar of that "liquidation" value. For a follower of `[[Value Investing]]`, a low P/B ratio can be a powerful signal that a stock might be on sale, trading for less than its tangible worth. It's a foundational tool from the playbook of the great `[[Benjamin Graham]]`, who used it to uncover solid, unglamorous companies that the market had overlooked.
===== How It's Calculated =====
Calculating the P/B ratio is straightforward and can be done in two primary ways. Both methods yield the exact same result.
==== The Per-Share Method ====
This is the most common approach for individual investors. You simply take the current stock price and divide it by the company's `[[Book Value Per Share]]`.
  * **Formula:** P/B Ratio = `[[Share Price]]` / `[[Book Value Per Share]]`
Most financial websites will have the `[[Book Value Per Share]]` readily available, making this a quick and easy calculation.
==== The Company-Wide Method ====
This method looks at the company as a whole. You divide the company's total `[[Market Capitalization]]` by its total `[[Book Value]]`.
  * **Formula:** P/B Ratio = `[[Market Capitalization]]` / Total `[[Book Value]]`
Remember, `[[Book Value]]` is simply a company's Total Assets minus its Total Liabilities, a figure you can find on the company's balance sheet.
===== Interpreting the P/B Ratio =====
The beauty of the P/B ratio lies in its simplicity. It provides a quick snapshot of how the market values a company relative to its on-paper net worth.
==== The Value Hunter's Viewpoint ====
  * **Low P/B (Typically below 1.5):** This is where value investors get interested. A P/B ratio below 1.0 theoretically means you could buy the company for less than the value of its net assets. It suggests the stock is out of favor and potentially undervalued. A P/B between 1.0 and 1.5 might still indicate a bargain, especially for a high-quality company.
  * **Moderate P/B (Typically 1.5 to 3.0):** This often indicates a company that is fairly valued by the market. It's neither a screaming bargain nor wildly expensive.
  * **High P/B (Typically above 3.0):** The market believes the company is worth far more than its stated net assets. This is common for growth stocks, where investors are pricing in high future earnings and significant `[[Intangible Assets]]` like brand power or proprietary technology. For a value investor, a high P/B requires a very high degree of confidence in the company's future.
===== The Caveats: When P/B Can Mislead =====
While powerful, the P/B ratio is not a silver bullet. Using it without understanding its limitations can lead you straight into a `[[Value Trap]]`.
==== Mismatched Industries ====
The P/B ratio works best for asset-heavy industries like manufacturing, banking, and insurance, where tangible assets form the core of the business. It is far less useful for:
  * **Technology & Software Companies:** Their value is in code, patents, and user networks—`[[Intangible Assets]]` that are poorly reflected on a balance sheet.
  * **Service & Consulting Firms:** Their primary "asset" is their people, which doesn't show up in `[[Book Value]]` at all.
==== Accounting Quirks ====
A company's `[[Book Value]]` is an accounting figure, not necessarily an economic reality.
  * `[[Goodwill]]`, an intangible asset recorded after an acquisition, can artificially inflate `[[Book Value]]` and make the P/B ratio seem deceptively attractive.
  * Conversely, assets like real estate might be recorded at their historical cost from decades ago, making the `[[Book Value]]` far lower than its true market value.
===== Capipedia's Practical Pointers =====
To use the P/B ratio effectively, keep these key points in mind.
  - **Never Use in Isolation:** P/B is a starting point, not the destination. Always use it as part of a broader analysis that includes other metrics like the `[[P/E Ratio]]`, `[[Dividend Yield]]`, and a deep dive into the business itself.
  - **Compare Apples to Apples:** The most potent use of the P/B ratio is for comparison. Don't compare a bank's P/B to a software company's. Instead, compare a company's P/B to its direct competitors and its own historical P/B range to see if it's cheap //relative to its peers and its past//.
  - **Question the Book Value:** Before getting excited about a low P/B, glance at the balance sheet. Is the `[[Book Value]]` made up of solid assets like cash and property, or is it bloated with `[[Goodwill]]` from a questionable acquisition? This extra step can save you from costly mistakes.
