We know that market trends only 30% of the time and remaining 70% of the time it stays in range bound, which immensely helps the option sellers because the more market stays in range bound, higher the decay of premiums.
The above chart is the daily return distribution of Index, we could see more number of times Nifty and Bank NIFTY moved between -0.30% to 0.30% on daily basis, only lesser number of days it has moved wildly on either side, if we follow ATM short straddle strategy, with a fixed stop loss, then we can control our risk when market moves wild and also we can continue to make profits when market stays in range bound.
We used stockmock platform to test this ATM Short straddle strategy
We short one lot of ATM options at 9:20 am every day with 25% stop loss on each leg,we will choose weekly expiry not monthly expiry as the decay is more with weekly options.
For example, if we short ATM CE options at Rs.100, then our stop loss is 125, when that is reached we exit ce, if not we exit by EOD only. Please note that we exit only the strike that hits the stop loss, not both legs. Here’s the gross result
