Book value per share (BVPS) measures the accounting equity attributable to common shareholders on a per-share basis. It helps investors compare the stock price with the company’s recorded net asset value.
$$
\text{BVPS} = \frac{\text{Total Shareholders' Equity} - \text{Preferred Equity}}{\text{Outstanding Common Shares}}
$$
The subtraction for preferred equity matters because BVPS is focused on common shareholders.
Why BVPS Matters
BVPS is useful when analysts want to:
- compare stock price with accounting value per share
- support price-to-book ratio analysis
- evaluate asset-heavy businesses where balance-sheet values are more informative
- judge whether equity has been diluted across a rising or falling share count
It is not a full valuation model, but it is a useful anchor.
Worked Example
Suppose a company reports:
- total equity of
$900 million
- preferred equity of
$100 million
100 million common shares outstanding
Then:
$$
\text{BVPS} = \frac{900 - 100}{100} = 8
$$
BVPS is $8 per common share.
If the stock trades at $16, investors are paying 2x book value per share.
BVPS vs. Market Price
BVPS is an accounting measure.
Market price is a forward-looking market judgment.
That means a stock can trade:
- above BVPS if investors expect strong future profitability
- near BVPS if the business is viewed as ordinary or asset-driven
- below BVPS if investors distrust the assets or expect poor returns
When BVPS Is Most Useful
BVPS tends to be more useful in:
- banks
- insurers
- industrial firms
- other asset-heavy companies
It is often less informative in businesses where economic value comes mostly from brand, software, network effects, or other intangibles that accounting does not fully capture.
FAQs
Is book value per share the same as stock price?
No. BVPS is based on accounting equity, while stock price reflects market expectations and trading conditions.
Can BVPS be negative?
Yes. If liabilities exceed assets, equity can be negative, which can make BVPS negative as well.
Does a stock trading below BVPS always mean it is cheap?
No. It may indicate undervaluation, but it can also reflect weak profitability, poor asset quality, or expected losses.
