The strategy that actually built his fortune was buying tiny, unloved companies for less than the value of what they already own. This tool runs that screen for real: enter tickers, it pulls live fundamentals, computes Price/Book, and flags anything trading below book. Nothing here is fabricated — every number is fetched at the moment you run it. Educational research tool, not investment advice.
Each ticker is scored 0–7 against these filters. A stock is a PASS when it clears your minimum score. The core filter is P/B below 1.0 = trading below book value.
How the math works (nothing hidden): Price/Book comes straight from Yahoo's defaultKeyStatistics.priceToBook; where you see Book/share it's bookValue. Margin of safety = 1 − P/B (only meaningful when P/B < 1). Debt/Equity is Yahoo's percentage figure. The 0–7 score simply counts how many of the seven filters each name clears against the thresholds you set above. No results are stored, ranked, or fabricated — refresh and the numbers update to whatever the market says right now.
