Being new to selling putts, one of the most difficult decisions I face is deciding which expiry month to select. Does anyone have any interesting guidelines or views ? For example at the moment I am considering selling the GXO 1000 Putt ( Glaxcosmithkline UK share @ 1000 UK pence ) GXO closed at 1270p which means the 1000 is currently 27% below the price. At 1000 GXO pays a nice 6% dividend, so I am more than happy to take the shares if put on. The June 1000 ( 5 months away ) sells for 7.5p The September 1000 ( 8 months away ) sells for 17.5p Here in the UK our contracts are for 1000 shares. So running the options to expire the premium return on the June putt would be 75/5 = 15 GBP per month Whilst on the September putt it would be 175/8 = 22 GBP per month. Which option would you sell and why ?
