This presentation summarizes the results of backtesting various options trading strategies on the CNX NIFTY index. It finds that a short strangle strategy outperforms a long strangle strategy, with higher probability of profits and lower maximum drawdowns. A 2% range strategy, where options are purchased at strikes 2% from the current price 5 days before expiry, has around an 83% probability of profit over 5 years based on backtesting, but carries risk of large losses if the price moves outside the range. Overall, the presentation recommends short-term options strategies for risk-averse investors and considering foreign investment patterns to predict market trends.
