Options question of the week: First #Harvey, then #Irma, now #Jose & more. We prep houses/cars/family for #disasters. How do you prep your portfolio?

• Get Long $VIX/$VXX/$UVXY
• Go To Cash/T-bills
• Buy Index/Stock Puts
• "Risk Assets" - Gold, etc.

ANOTHER options question of the week: $EFX exec. cashes out #Options worth $584k a month before disclosing massive breach. $EFX off near 35%. Well-timed, lucky or illegal?

Listener Questions and comments:

• Comment from Kathryn Corby: How do you guys know the put buyer is not selling near-the-money puts at the same time? That would be smart.
• Question from Richard D - Dear Derivative Dignitaries, Its your long time listener "Richard D" again. I couldn't write over the last few weeks because I did not have a new appropriate salutation for you!

I have recently been looking at some Apple calendars. I'll see for example I can get near term Apple calendars near the strike using puts for about 5% less than calls.

For example, recently, with the equity price around $161 a long 162.5 Sept 22 / 29 call calendar would go for about $.62 while the puts about $.59. Aren't these supposed to be the same and since they are not can you arb this, especially if you do not have commission charges.

Thanks and I appreciate the wealth of knowledge AND laughs I get from your show. V/R, Richard

• Question from SacMan12: What are the odds that SVXY gets back to 70?

Around the Block: Will we hold 2500? Is it a buying opportunity in SLV? Risk reversals in VIX?
