Weekly options are active in the Bank Nifty. That brings us back to the core question; why have weekly options not taken off in a big way across products. Firstly, we need to give this product more time to catch the fancy of investors. Secondly, for option buyers, it offers a lower cost option to participate in the F&O market and take positions in the Bank Nifty at lower cost. But at the end of the day, the success of any options market lies in the availability of enough traders to sell options. For option sellers, even globally, shorter options have not been attractive enough considering the lower premium income. That is likely to be a roadblock for the Weekly Options market.
