Option Cycle

An option cycle refers to the standardised series of expiry months available for options contracts on a given underlying security — determining which monthly (and in some cases weekly) expiry dates are available for trading at any given time. In India, NSE's equity derivatives framework provides index options (Nifty 50, Bank Nifty, FinNifty, Sensex) with weekly expiry contracts — Nifty 50 weekly options expire every Thursday, Bank Nifty every Wednesday, and FinNifty every Tuesday — in addition to monthly contracts expiring on the last Thursday of each month and quarterly contracts. Individual stock options in India are available on monthly expiry cycles — the last Thursday of the current month, the next month, and the month after (near, middle, and far month contracts). The option cycle determines how far into the future an investor can hedge or speculate using exchange-listed contracts. As each expiry date passes, a new expiry month is added to maintain the cycle. For options traders in India, understanding the option cycle is essential for selecting the appropriate contract for a given strategy — balancing the time value of premium with the desired hedging horizon or speculative time frame.
