Are you feeling that ce price is little low than it should be? The options price is based on the fut price. Let’s look at todays closing price. Around 10260 for fut and 10220 for spot.
If we look at atm 10250 pe ce options price, they look reasonably similarly priced.
What strikes me as little bit odd though is the price diff between strike and fut. Yesterday it was around 20,today its 40. Some time back, it was around 60. Usually this diff comes down to around 10-15 during day and even that didn’t seem to happen today. Good thing is if nifty holds its current level, fut price difference will eventually come down to spot price near expiry
