2. How Index Options Work
Option Types
You deal with two primary instruments:
Call Options (CE) – You profit when the index goes up
Put Options (PE) – You profit when the index goes down
Expiry Cycles
Both Nifty and Bank Nifty have:
Weekly expiry
Monthly expiry
Quarterly (some strikes)
Bank Nifty earlier had only weekly expiry on Thursday, but now expiries rotate due to SEBI’s rules. Nifty expires every Thursday as usual (unless it is a trading holiday).
Lot Sizes
Nifty lot size: typically 50 units
Bank Nifty lot size: typically 15 units
(These vary slightly during periodic revisions.)
3. Pricing Dynamics: Why Option Premiums Move
Option premiums are governed by:
i. Intrinsic Value
The real, quantifiable value.
CE intrinsic value = Spot price – Strike
PE intrinsic value = Strike – Spot
ii. Time Value (Theta)
Time value decreases as expiry comes closer.
Buyers get hurt by theta decay
Sellers benefit from theta decay
Bank Nifty has rapid intraday time decay, so sellers often dominate.
iii. Volatility (Vega)
Bank Nifty has higher volatility, meaning:
Higher premiums
Larger impact of news
Bigger risk and reward potential
iv. Delta
Measures how quickly the premium moves with respect to the index.
Example:
Delta 0.50 → Option moves 50% of index move
ATM options typically have delta ~0.5
Bank Nifty deltas shift faster due to rapid price movement.
