In India, option trading has emerged to be a major segment within the derivatives market. A few years ago, the flexibility of dealing with possibilities of developing strategies with even shorter time horizons was extended to traders with the introduction of weekly index and stock options. These weekly experiences provide opportunities to manage risk, to adjust the position very quickly, and also establish a short-term view on the direction of the market. If the market players understood how these contracts work and the types of strategies conceived around them, they would be better able to realign their trades in accordance with their goals.
Basic Features of Option Trading in India
Options are essentially derivative contracts that give the buyer the right, but not the obligation, to buy (in the case of a call option) or sell (in the case of a put option) the underlying (asset) at a predetermined price on or before expiry. In India, option trading is predominantly done on the NSE, where options on both indices (such as Nifty and Bank Nifty) and select stocks are available.
Introduction of weekly expiries was merely an enhancement to monthly contracts. That means a trader no longer has to wait till the last Thursday of the month; instead, for every Thursday, there is an option available to them for trading.
Importance of Weekly Expiry
There is interest and trading in such short-term options for the ability to establish and liquidate positions on a very short-term horizon. They command respect from traders who:
Hedge against sudden market movement in their short-term portfolios.
Based on the event calendar, decide to enter trades or positions, due to announcements of some economic measures in the market or for the earnings of some corporations.
After considering time decay, it is estimated that the values of weekly contracts are lost rapidly, barring strong price movement.
Specialized Strategies Using Weekly Expiry
Straddle Through Events
To enact a straddle, traders must buy a call option and a put option of the same strike price in a weekly expiry. This method is preferred when there is an important event that could cause significant price movement, such as a policy announcement. The idea is to profit from volatility in either upward or downward directions during the brief expiry period.
Short-Strangle in a Range-Bound Market
A short strangle is where an out-of-money call and an out-of-money put option are sold simultaneously. In weekly expiry, this setup can be used if a trader expects the market to stay within a predetermined range for the week. Here, the key aspect is that of time decay for the weekly contract.
Iron Butterfly Imparts Defined Risk
The Iron Butterfly is constructed by selling a call and a put at the same strike while simultaneously buying a higher strike call and a lower strike put. The shorter time for weekly expiry gives traders an extra edge to design an iron butterfly in the scenario in which they believe the market will hold the price level for a relatively small time.
Using Weekly Options for Covered Calls
If an investor owns stock, he/she may sell a weekly call option on the same stock, getting paid premium income from the option, while still holding onto the stock.
Account Structure, Setting Up, and Accessibility
For an investor to be able to start option trading in India, they must go ahead to open a demat account along with the trading account. Brokers usually combine these two services, and many advertise a free demat account just to put a lesser burden on the initial cost for new entrants. After having his account set up, a trader would be in a position to gain access to options contracts through online portals.
Conclusion
By excluding short-term holders, these weekly expirations give India out-and-out flexibility in option trading. Strategies that put straddles, strangles, iron butterflies, or covered calls into adaptation follow these short-term contracts around the different market scenarios. The first step toward becoming a participant in this niche would be based on trading account activation and setting up a free demat account. Understanding the peculiar characteristics of weekly options, then, would allow traders to tailor their positions around their expectations of the market over a short timeframe.
