P/B = Stock Price / Book Value Per Share
P/B below 1.0 means the stock trades for less than its net assets. Like buying a house for less than the value of its parts. Buffett looks for this.
P/B is most useful for asset-heavy industries (banks, insurance, REITs). It is less useful for tech companies where value comes from intangibles like software and brand.
Sit with the ideas.
A bank stock has P/B of 0.8x. What does this mean?
Identify the moat. Then size the position.
Pick a company. Articulate its moat in one sentence: switching costs, network effects, intangibles, cost advantage, or efficient scale. Paper-buy a position size proportional to your confidence in that moat surviving 10 years.
