Limited strikes

Why do they have limited number of strikes on the monthly's vs the weekly's I don't get it?

 

They'll only have as many strikes as they have liquidity to support.

 

Monthly's are generally more liquid then weekly's

 

what option?

 

This is a bad week for it because we have the monthlys up this week. But look at next month's strikes, and look how much more open interest the 6/16s has at those strikes vs. the intermediate.

 

Just all options that have weeklys and monthly. For example UNH strikes are 2 1/2 wide in the weekly's but 5 wide on the monthlys

 

How is that bad?

 

Calendars

 

Nothing magical about doing identical strikes as long as you are root time vega neutral.

 

risk reward is usually better on identical strikes on adjacent weeks
