Stock Options are a derivative instrument wherein the underlying asset is a corresponding Stock viz. RIL or SBI or TCS. All stock options have respective lot sizes, different strikes and multiple expiry periods. It is a derivative like Futures but unlike Futures your profit/loss will not be linear depending on the up move/down move in corresponding stock. Also we have to keep in mind that not all stocks will have respective options or futures derivatives, only select few stocks are allowed by SEBI to have derivatives in options and futures.

Things to remember while trading stock options and building options trading strategies in India

  • Illiquidity – In India, the depth of trading in stock options is still relatively shallow. A lot of stock options are illiquid with very few contracts traded and low open interest. Traders must bear in mind that the illiquidity of a stock options contract can severely impact trading strategies and profitability.
  • Determining fair value of options – Due to the wide bid-ask spreads in stock options contract, it may become difficult for stock options traders to judge the true value and price of an option contract. The bid for a contract would be Rs. 1 and the ask may be Rs. 8. In such a situation, it can be tricky for a trader to try and figure out the correct fair price of the option. We would recommend traders to calculate the stock options price/value on the SAMCO option price calculator.
  • Avoid Market orders while trading stock options in India. Due to the illiquid nature of contracts, placing market orders in stock options can be detrimental. It is advisable to trade in stock options only using the Limit order type.
