June otm calls seem to have a shrinking delta. I'm short a june otm call and as the market has advanced +5.50, the option has only advanced +0.5 which is a delta of only 0.09. A couple of days ago the delta for that option was over 0.25. This supports the idea that even if the call premiums are not extremely high, one can still make money by selling premium when expiration is near.
I think you are correct, we're shorting junes and they are shrinking quickly. It would be interesting to see if the market flatlines for the summer.
bought back june 1010 call at 4.0. Market looks as if wants to close higher on the day. After Wednesday's late rally and Thursday's (today) rally, i'll take profits on the option. Still looking for another opportunity to sell call premium.
IMHO I wouldn't sell calls until 2 weeks before expiry, and their at least 6 % OTM with at leat 17% implied vol in the price, and do it on a friday afternoon and get 2 days of time decay free (debatable)
