Quote from dreamer:
You haven't done your homework, rosa.
For example, the quote on the S&P 900 call is 26.30/27.50 and the put is 26.10/28.00. For simplicity and discussion purposes, let's say it is 27 on either, that's in the middle.
Selling an option for 27 when the underlying is 900 gives a return of 3% on the strike or symbol price.
Why would I trade the S&P when I can get 10% or more regularly on other symbols??
I apologize. I find I am teaching, or maybe preaching, and I do not want to do either. I will refrain in the future.
You are not teaching anything here, professor.
I like to think in volatility terms when buying and selling options, not in terms of some kind of 'yield'.
What happens to the put price when volatility goes to infinity, sherlock? - Say, for the 15 put, when stock is at 15? The put will be worth $15. Wow, how is that for a 100% return on your strike?
It's great, but only until the next stock tick, when stock goes to 100, how do you like your put sale then?
Of course, you can say, this is all too theoretical, but my point is the option is trading where it's trading because of the market's perception of what vol is.
If you divide everything by 100 in your example you get the S&P trading at $9.00 and the value of the option $0.27. Now you're saying you like to sell an option on another stock that's trading at $9 better, just because it's $1.25 bid for.
So you'd probably also rather buy junk bonds than t-bonds, because they have a greater return, right?
This much for oranges and apples, and good idea refraining from teaching, as your lesson has not taught me anything yet.
