How to use a stock screener (the right way)

Most screeners fail because they chase "cheap" stocks without checking quality. A good screener combines value, profitability, financial safety, and (optionally) momentum.

A simple starter screen

  • Positive free cash flow
  • Reasonable valuation (avoid extreme multiples)
  • Solid profitability (ROE / margins)
  • Manageable leverage (debt-to-equity, interest coverage)

Common mistakes

  • Using P/E alone (ignores balance sheet and cash flow).
  • Buying "cheap for a reason" without checking distress risk.
  • Ignoring sector differences (multiples vary by industry).
