Definition
PBV (Price to Book Value) is a ratio comparing a stock's market price to the company's book value per share. Simply put, PBV shows whether the market values a company higher or lower than its net assets. A PBV below 1 means the stock price is cheaper than the company's net asset value.
Simple Explanation (Analogy)
PBV is like buying a used car. A 2020 Honda Jazz's official (book) value might be $18,000. If someone sells it for $20,000, the PBV is 1.1x (above book value). If sold for $15,000, the PBV is 0.83x (below book value). Stocks work the same -- some are priced above their 'contents,' some below.
Indonesian Stock Example
Bank BCA (BBCA) typically trades at a PBV of 4-5x, meaning the market values BBCA at 4-5 times its book value. Why so expensive? Because BBCA is known for its best-in-class asset quality and consistent profitability. Meanwhile, smaller banks might trade at PBV of only 0.5-0.8x because their quality is perceived as lower.
How to Use
- Compare a stock's PBV with its historical average. If BBCA usually trades at 4.5x but is now at 3.5x, it might be at a relative 'discount' to itself.
- Compare PBV across companies in the same sector. BBCA at 4.5x vs BBRI at 2.5x -- this doesn't mean BBRI is absolutely cheaper, but it's worth considering.
- PBV is most relevant for banking and financial sectors. For tech or service companies with few physical assets, PBV is less representative.
Common Mistakes
- Assuming low PBV automatically means cheap. A low PBV could signal the company is in trouble -- its assets may be impaired or business declining. Cheap isn't always good.
- Comparing PBV across different sectors. A mining company's PBV can't be compared with a bank's PBV -- different industries, different standards.
- Looking only at PBV without checking ROE (Return on Equity). High PBV is justified if ROE is also high. High PBV + low ROE = likely overvalued.

What's an ideal PBV?
There's no single ideal number for all stocks. For banking, PBV of 1-2x is generally considered fair for mid-tier banks. But premium banks like BBCA can be fairly valued at PBV 4-5x due to far-above-average quality. Always compare with peers and historical data.
Why do some stocks have PBV below 1?
PBV below 1 means the market values the company below its net asset value. This could mean: (1) the stock is genuinely undervalued and has potential, or (2) there are serious issues making investors skeptical about its asset value. Deeper research is needed.
