PIDILITIND Options — Where Positioning Sits Today

Where PIDILITIND open interest sits

The heaviest call open interest is at the 1,700 strike, holding 3,11,500 contracts — 26.8% of all PIDILITIND call open interest on the board, 8.27% above the spot of 1,570. Call open interest concentrated above price is commonly read as resistance, on the reasoning that writers there are defending the level. It is a crowding observation, not a rule — the level holds until that open interest unwinds.

On the put side the weight is at 1,500 with 1,64,000 contracts, 16.8% of PIDILITIND put open interest, 4.47% below spot. Put open interest concentrated below price is usually treated as support for the same reason, and breaks the same way.

Both sides are unusually concentrated — the top strike alone carries 26.8% of its side. A distribution that peaked tends to behave like a genuine pin while it lasts, and to move fast when it breaks, because there is little open interest at the next strike to slow it.

What PIDILITIND's PCR is saying

PIDILITIND is carrying 9,77,500 contracts of put open interest against 11,61,000 of call, a put-call ratio of 0.84 — broadly balanced positioning. PCR has no universally good value; it is read against its own recent range, and the direction it is moving carries more than the level.

It opened the session at 0.84 and has held to 0.84 — a move of 0.00. That is effectively flat: positioning has not changed sides today.

PIDILITIND against its max pain

Max pain for PIDILITIND computes to 1,620, with spot at 1,570 — 3.17% below it. That strike is where the total value of all open contracts expiring would be lowest. It is arithmetic on the current open interest distribution, not a forecast, and the distribution keeps changing.

The curve is defined around it: the nearest strike either side costs writers 5.8% more than 1,620. A trough that distinct is a stronger reference than a flat basin, though it still describes positioning rather than predicting settlement.

There are 21 sessions to expiry. This far out the figure moves as positions roll, and it is least informative early in a series — worth watching for direction of travel rather than as a target.

What changed in PIDILITIND today

The biggest unwind is −1,500 put contracts at 1,440. Positions closing matters as much as positions opening — a level defended by open interest stops being defended when that open interest leaves, and a break through a strike that is unwinding is a different event from a break against one that is intact.

Change is measured against this session's opening snapshot rather than the previous close, so the overnight gap and the positions rolled at the open do not swamp the reading.

The move priced into PIDILITIND

The at-the-money straddle on PIDILITIND costs 55.05 — 24.45 for the call and 30.60 for the put at the 1,600 strike. That sum is what the market charges to be covered in either direction, which makes it the move being priced in: about 3.51% of spot, or roughly 1,545 to 1,655 by expiry on a breakeven basis.

The straddle has moved 0.0% since the open. That is close to flat, so today's decay and any volatility move have roughly offset.

Implied volatility at the money is 17.9% on the call and 18.0% on the put. The two legs are priced almost identically, so there is no meaningful skew at the money right now.
