Welcome to today’s F&O Insights! We’re unpacking Futures & Options (F&O) data to help you spot market moves, whether you’re new or leveling up. This edition dives into new expiries launched for 24 April 2025, offering a fresh view on trader sentiment across key stocks.

Section 1: Understanding Stock Activity Through OI Changes

Here’s what’s moving in key stocks based on price changes and Open Interest (OI) shifts.

Underlying Price Change Call OI Chg Put OI Chg Call Explanation Put Explanation
BAJFINANCE 8,783.40 2.20% 649 1407 Long Buildup Long Buildup
SUNPHARMA 1,710.20 -3.38% 2710 4457 Short Buildup Short Buildup
AXISBANK 1,096.05 0.57% 4234 1636 Long Buildup Long Buildup

RELIANCE 1,200.40 -3.87% 32158 7361 Short Buildup Short Buildup

What Do These Terms Mean?

  • Long Buildup: OI rises with price moving favorably—up for calls (bullish) or down for puts (bearish). Traders are buying options, expecting that direction.

  • Short Buildup: OI rises, but price moves against buyers—down for calls (bearish) or up for puts (bullish). Suggests option selling.

  • Short Covering: OI drops with price rising (for calls) or falling (for puts). Short sellers buy back options, fueling the move.

  • Long Unwinding: OI drops with price falling (for calls) or rising (for puts). Long holders exit, signaling doubt.

Quick Take: Sharp Short Buildup (e.g., RELIANCE’s 32158 calls) with big drops signals strong bearish sentiment—watch for support!

How to Understand Volume/OI Ratio

  • What It Is: Compares today’s trading volume to existing OI. A higher ratio means more new trades.
  • What It Suggests:
    • Above 2: Notable interest—traders see this strike as key (e.g., RELIANCE’s 4.88 at 1210 PE).
    • Above 5: Strong activity, often tied to big expectations (e.g., SUNPHARMA’s 9.90 at 1700 PE).
    • Below 1: Quiet—positions are likely being held or closed.
  • Why It Matters: High ratios highlight “hot” strikes—potential support or resistance zones.

Final Thoughts

F&O data reveals a split market—OI shifts show bullish finance and bearish pharma/oil, while high Volume/OI Ratios (like SUNPHARMA’s 9.90) spotlight key action. Pair these clues with charts to navigate the mix!
