Welcome to this today’s F&O Insights! We’re breaking down Futures & Options (F&O) data to help you spot market moves, whether you’re new or growing your skills.
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 |
|---|---|---|---|---|---|---|
| NTPC | 8950 | 3.11% | 420 | 1398 | Long Buildup | Long Buildup |
| KOTAKBANK | 2077.3 | 2.05% | 2294 | 5556 | Long Buildup | Long Buildup |
| AXISBANK | 1341.6 | 1.51% | -725 | 1645 | Short Covering | Long Buildup |
| SBIN | 3598.25 | 0.97% | -5729 | -1106 | Short Covering | Short Covering |
| ICICIBANK | 11877 | 1.25% | 180 | -1595 | Long Buildup | Short Covering |
| BAJFINANCE | 1594 | -1.36% | -4698 | 197 | Long Unwinding | 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: High Put OI Chg (e.g., KOTAKBANK’s 5556) with Long Buildup often signals hedging alongside bullish moves—watch for confirmation!

- What It Is: Compares today’s trading volume to existing OI. A high ratio signals fresh trades.
- What It Suggests:

- Below 1: Quiet—positions are being held or closed.
- Why It Matters: Ratios like 17.46 or 12.57 flag hot zones—potential breakout or support levels!
