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.

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.
