Recently, while analyzing the fundamentals of stocks, I found that many people have misconceptions about the understanding of book value per share. Today, I want to talk about this often-overlooked but actually quite important indicator.

Book value per share (BVPS) essentially means the company's net assets divided equally among each share, reflecting the actual asset base owned by shareholders after deducting all liabilities. Many people ask, is this the true value of the stock? Actually, no. BVPS is just an accounting perspective of the company's current book status and cannot be directly equated with market value or future stock prices.

The calculation is quite simple: shareholders' equity divided by the number of outstanding shares. For example, if a company has shareholders' equity of 1.5 billion yuan and 1 billion shares outstanding, then the BVPS is 1.5 yuan. Some people see this number and think, "If the stock price is below 1.5 yuan, it's cheap," but this logic can easily lead to pitfalls.

Here's a point that is often overlooked: a stock price above BVPS isn't necessarily expensive, and below BVPS isn't necessarily cheap. The market is willing to pay a premium for the company's future growth, so high-tech and software companies often have stock prices far above their BVPS, but these companies are still worth investing in. Conversely, some companies have stock prices below BVPS, which might be due to declining profits, deteriorating asset quality, or bleak industry prospects.

This leads to the true purpose of BVPS. First, it can serve as a reference for assessing a company's financial stability, especially meaningful for capital-intensive and cyclical industries. Second, it can be used together with the price-to-book ratio (PBR) to judge valuation levels, but only meaningful when comparing companies within the same industry and business model. Third, in extreme cases (such as liquidation), BVPS can serve as a basis for distributing shareholders' equity.

I notice a phenomenon: many people tend to fall into a dead end when using BVPS for stock selection. For industries like manufacturing, finance, and industrials, BVPS is indeed an important indicator because asset structures are clear. But for tech, software, and content companies, it’s different. Their value mostly comes from intangible assets, technology, brands, or traffic, so book value isn't the main reference. For example, NVIDIA, Microsoft, and Netflix have relatively low BVPS, but who would say they are not worth investing in?

Therefore, the idea that higher BVPS is always better is actually a misconception. If you pursue high BVPS blindly, you might miss many genuine investment opportunities. A more practical approach is to look at BVPS together with PBR, EPS, ROE, gross profit margin, and growth rate, and then consider industry characteristics to make judgments.

It's also easy to quickly check BVPS. Most stock trading platforms and financial report websites can display it directly, or you can calculate it yourself from the company's financial statements using the formula. If you want to understand a company more deeply, I suggest not just focusing on BVPS alone, but viewing it within the entire financial indicator system, so you can get closer to the company's true investment value.
