Why score stocks against 5 legendary investors?

The most common pitfall for individual investors is confusing "a great company" with "a great stock". A growing business at PER 100 is still expensive; a 30% operating margin business with debt 5x equity is still risky. Warren Buffett · Benjamin Graham · Peter Lynch · William O'Neil · Philip Fisher — these five investors left behind quantitative criteria proven over 50-100 years. StockInto encodes their criteria and scores any stock in under a second.

For example, Buffett's ROE 15%+ AND positive FCF AND debt-to-equity ≤ 100% applied identically to every stock means objective comparison free from emotion, rumor, or hype.

Frequently Asked Questions

What PER is considered expensive?

It depends on the sector, not absolute value. Tech stocks (Apple, MSFT) usually trade at PER 25-35, while financials trade at 10-15. StockInto applies sector-median thresholds. See the DCF Guide for valuation details.

Should I always buy A-grade stocks?

No. An A grade just means the stock passes a high percentage of quantitative criteria; it does not predict future price movement. Business model, management quality, industry cycles, and macro environment aren't captured in numbers. Use grades as a screening filter only.

How is DCF fair value calculated?

5 years of FCF growth + terminal value (Gordon Growth) discounted by WACC. Terminal growth fixed at 1.5% (below inflation, conservative). Discount rate computed dynamically via CAPM-based WACC (clamped 7.5-14%). Full breakdown in the DCF Guide.

Where does the Korean stock data come from?

Prices from FinanceDataReader (KRX), financials from DART (Korean SEC equivalent). yfinance has known issues with Korean data, so we don't use it for Korea. US stocks use SEC EDGAR 10-K and 10-Q for self-calculated TTM (trailing 12 months) figures.
