Low P/E Ratio

Find stocks with attractive price-to-earnings ratios:

typescript

import { StockScreener, StockField } from 'tradingview-screener';

const screener = new StockScreener();

screener
  .where(StockField.PRICE_TO_EARNINGS_RATIO_TTM.between(5, 15))
  .where(StockField.MARKET_CAPITALIZATION.gt(1e9))
  .where(StockField.NET_INCOME_TTM.gt(0))  // Profitable
  .select(
    StockField.NAME,
    StockField.PRICE,
    StockField.PRICE_TO_EARNINGS_RATIO_TTM,
    StockField.MARKET_CAPITALIZATION

Best Practices

Multiple Metrics: Use several valuation ratios together (P/E, P/B, P/S, EV/EBITDA, P/FCF)
Quality Matters: Focus on ROE, ROA, and ROIC to identify efficient companies
Margin Analysis: Strong operating and net margins indicate pricing power
Financial Health: Check debt ratios and liquidity ratios (current ratio)
Growth Context: Even value stocks should show revenue growth
Profitability: Filter for positive earnings and cash flow
Size Matters: Use market cap filters to avoid illiquid stocks
Avoid Value Traps: Combine value metrics with quality indicators
