What is PEG Ratio?

PEG = PE ÷ earnings growth rate — lower may suggest growth relative to price.

Formula

PEG Ratio = P/E Ratio ÷ Annual EPS Growth Rate

Indian market context (NSE)

Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how PEG Ratio shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

Nifty at 24,300: index-level peg ratio aggregates 50 names — useful macro filter for allocation, less useful for Bank Nifty scalps the same afternoon.

Reliance Industries perspective

PEG Ratio for Reliance at ₹1,300: pull from latest exchange filings and investor presentation — compare to Nifty 50 median for context, not as a timing signal for intraday futures.

How to validate

  • Minimum sample: 30 closed trades on one strategy tag before trusting PEG Ratio.
  • Check for one outlier week inflating PEG Ratio — export largest winners and losers.
  • Recompute PEG Ratio after including brokerage, STT, and slippage on F&O tags.
  • Compare PEG Ratio on the same date range as profit factor and max drawdown.

How to track in TradeLyser

  • Open Strategy Board or analytics → filter by strategy tag and review period.
  • Locate the widget or column reporting PEG Ratio (or export trades to compute manually).
  • Store snapshot values in weekly review: PEG Ratio, profit factor, drawdown, trade count.
  • If PEG Ratio is custom, add a spreadsheet column fed from TradeLyser CSV export.

Best practices

  • Publish PEG Ratio per strategy, not only at account level.
  • Use the same calculation window (weekly vs monthly) year-round.
  • Pair PEG Ratio with sample size in every review slide or note.
  • Reconcile PEG Ratio with broker statements before tax filing.

Common pitfalls

  • Changing rules after fewer than 20 trades because PEG Ratio moved slightly.
  • Mixing intraday and positional tags when computing PEG Ratio.
  • Ignoring costs so PEG Ratio looks better than banked P&L.
  • Letting one outlier trade dominate the PEG Ratio reading.
