Why are prices of ESTX50 ATM options so different ?

Sorry, but dividends increase the value of puts, because you can hedge with the basket of stocks and get the dividend, and have the effect of lower the call values for the same reason. I can sell the call vs a basket of stocks and get the dividend.

 

What is your problem?
I just made my own calculation and detected that something indeed is fishy in this pricing as shown in the OPs screenshot.

 

Hmm. then my options calculator has maybe a bug, I'll check. Thx for the info.

Update:
I have checked the case and my calculation is correct.
Can it be maybe that you are wrong in your above assumption? I mean are you sure?

 

Not likely.

 

Further research shows that it is indeed the effect of dividends, yes dividends make puts more expensive.
When calculating one should not mix dividend with interest rate ;-)

 

Negative rates work like dividends which is why hard to borrow securities have elevated puts.

 

This:

You are assume that everyone else is wrong when you have no idea what you are talking about.

Anyway, the adult thing to do is put you on ignore from here. Good luck selling your system.

No, that is just your own sick interpretation.

And you landed in my Ignore list! Simply don't reply to my postings in the future.

 

My 2 cents:

Puts in stocks is basically always more expensive than calls. To serve for hedging purpose.

Other than the deltas, you need to check whether the same or similar pricing difference appearing in some other indexes options.

It sees a yes to me for just now. That could mean the major factor currently would be its IV, which decides its premium/price of options.

AFAIK, the market now tells you its directional bias that you might or might not feel agreeable/comfortable with this bias.

 

This case is an interesting example.
I just wonder how to calculate from the given parameters in the screenshot (prices, strike, volatility, time, etc.)
the dividend% that is included (hidden) in the prices?
When I try to find it iteratively using BlackScholes I get a dividend% of about 2.65%, but I'm not sure if that can be correct.
Other values I got: 7%, 4.67%. Not sure which comes closest. For the Call side it fits, but not for the Put side.
Maybe an arbitrage opportunity here? ;-)
