Formula Used
- P/E Ratio = Market Price per Share ÷ EPS
- P/B Ratio = Market Price per Share ÷ Book Value per Share
- Earnings Yield = EPS ÷ Price × 100
- FCF Yield = Free Cash Flow per Share ÷ Price × 100
- Margin of Safety = (Intrinsic Value − Price) ÷ Intrinsic Value × 100
- Graham Number = √(22.5 × EPS × Book Value per Share)
- Graham Formula Value = EPS × (8.5 + 2 × Growth Rate) × (4.4 ÷ Required Return)
- Blended Fair Value = Average of valid positive fair value estimates
- Overall Screen Score = Weighted points from valuation, quality, and balance sheet rules

FAQs
1) What does this value stock screener measure?
It combines valuation, profitability, cash flow, and balance sheet checks. The tool helps you see whether a stock looks cheap, durable, and financially stable under your chosen rules.
2) Is a low P/E ratio enough to call a stock undervalued?
No. A low P/E can appear attractive while the business remains weak. It should be reviewed alongside debt, book value, free cash flow, returns, and the gap between price and fair value.
3) Why is margin of safety important?
Margin of safety helps protect against estimation errors. Buying below estimated fair value creates room for mistakes, slower growth, or weaker market sentiment while still supporting a reasonable return.
4) What happens if EPS is zero or negative?
The P/E ratio and some fair value methods become unreliable or unavailable. The calculator will still review other factors, but the final screen may weaken because profitable earnings are central to classic value methods.
5) Why do debt to equity and current ratio matter?
Value traps often look cheap because financial risk is rising. These two measures help you test leverage pressure and short-term liquidity before treating a low valuation as a genuine bargain.
6) Should I rely only on the Graham number?
No. The Graham number is useful, but it is only one estimate. A stronger review blends several valuation methods with quality checks, cash flow strength, and your own margin of safety target.
7) Can this screener be used for banks or insurers?
Use caution. Financial firms have different balance sheet structures, so current ratio and debt measures may be less meaningful. For those sectors, add industry-specific ratios before making a decision.
8) Does a higher dividend yield always improve the result?
Not always. A very high dividend yield may reflect falling price, weak coverage, or future cuts. Yield works best when supported by healthy free cash flow, earnings quality, and manageable leverage.
