How to Identify an Undervalued Stock: 7 Proven Methods

how to pick stocks for swing trading

Investing in undervalued stocks is a classic strategy used by value investors like Warren Buffett. When learning how to identify an undervalued stock, the idea is simple—buy low, sell high. But how do you know when a stock is truly undervalued?

In this guide, you’ll learn how to identify undervalued stocks using reliable financial metrics, valuation models, and qualitative factors.


1. Look at the Price-to-Earnings (P/E) Ratio

The P/E ratio compares a company’s stock price to its earnings per share. A lower P/E compared to industry peers may indicate undervaluation.

Example:

  • Stock A P/E = 10
  • Industry average P/E = 18
    → Stock A might be undervalued

Tip: Use forward P/E for better forecasting.


2. Check the Price-to-Book (P/B) Ratio

The P/B ratio compares a company’s stock price to its book value. A value below 1 suggests the stock is trading for less than its actual net assets.

Formula:
P/B = Stock Price / Book Value per Share

This is especially relevant for banks, insurers, and asset-heavy companies.


3. Analyze the PEG Ratio

The PEG ratio adjusts the P/E ratio for earnings growth.

Formula:
PEG = (P/E) / EPS Growth Rate

A PEG below 1 is often seen as undervalued.

Example:

  • P/E = 15
  • EPS growth = 20%
    → PEG = 0.75 = undervalued

4. Compare Intrinsic Value vs Market Price

Use Discounted Cash Flow (DCF) models to estimate a stock’s fair or intrinsic value. If the market price is significantly below this value, the stock may be undervalued.

Tools to use:

  • Simply Wall Street
  • Finbox
  • TIKR Terminal

5. Look for Low Debt and Strong Cash Flow

Undervalued stocks with strong fundamentals include:

  • Low debt-to-equity ratio
  • Positive and growing free cash flow
  • Consistent operating margins

These signal financial strength even if the stock is priced low.


6. Evaluate Recent News or Temporary Issues

Sometimes stocks become undervalued due to temporary problems like:

  • Market corrections
  • Sector-wide fear
  • Earnings miss despite good fundamentals

Look beyond the noise and assess long-term potential.


7. Use Screener Tools

Set up custom stock screeners with filters like:

  • P/E < Industry Avg
  • PEG < 1
  • Dividend Yield > 2%
  • Debt/Equity < 0.5
  • ROE > 15%

Recommended screeners: Screener.in, Finviz, TradingView, TIKR.


Final Thoughts

Identifying undervalued stocks takes time, but it’s one of the most rewarding paths to long-term wealth. Focus on value, not price. Use a mix of quantitative data and qualitative analysis to build a confident investment case.
