it was amazing to see that though today nifty went up nearly 40 points but ce in jan series abv 6400 depreciated in its values and today was just beginning of new series...may be due to drop in jan Nifty fut prem but still jan fut was up 20 points from prev close.

does it indicate any trend for coming days???or is it simply due to reason that smart investor think that nifty may not see big upmove this series

option strategy for expiry day:

buy 6100ce jan series and 6100pe dec series when nf trades at near 6100 levels,if nifty moves up near 6120-30 range then book ce and hold pe,
if nifty moves down then book pe and ce near 6040 range,appreciation in 6100 pe will be much more than depreciation in 6100ce

if can hold patience try this strategy in later part of the day
