How the Mechanism Operates
Options represent asymmetric financial contracts. When you buy a Call option on Nifty @ 24,500 for a premium of ₹150, you are purchasing the legal right to purchase Nifty at 24,500 on expiry date. If Nifty closes at 25,000, your option is worth ₹500 (Gross profit ₹350 per share). If Nifty collapses to 22,000, you simply choose not to exercise your right; your loss is strictly capped at the ₹150 premium paid.
The option seller takes the exact opposite side of this trade. In exchange for receiving the ₹150 premium upfront, the seller assumes the financial obligation to deliver index value above 24,500, absorbing all downside if the market explodes higher.
Defined Risk Protection during Unexpected State Election Results
Trader anticipated high volatility on election counting morning. Held Long 24,000 Puts bought @ ₹90.
Market opened with an unexpected 1,200-point gap down. The put option surged from ₹90 to ₹850.
Trader realized +₹19,000 per lot with a strictly capped initial risk of only ₹2,250 (₹90 × 25).
