Tabb Group is a consulting firm that specialized in the business of capital markets. They were like a McKinsey for big hedgefunds and bank trading divisions.

He only quoted Larry Tabb because he needed to find a "Tabb."

Imagine Larry Tabb saying you only need put call parity to value options.

ok let me find the article for you when he said it, you obviously didn't pay much attention :)
 
For a payment-for-flow broker like RobinHood, can the customers choose where to route? Or all orders are automatically going to the MMs?

I've got hundreds of Tabb emails in my inbox, so yeah, it proves I'm not stupid enough to lie about being on TabbForums.

You're a broke Eastern Euro troll with dirt floors.

so maybe you could ask about your BS model on that forum LOL :)

don't forget to mention the "put-call parity" so you don't come across as a total amateur with your BS model :)
 
I mean, who in his fucking right mind can believe again in the BS model with all the design flaw it has? I think even Black came on record before he died saying that the model was fucking flawed!!!

Dude, let me help you through your 4-step newb/vol-retard journey.

1) BSM is incredibly useful in relative value (skew/smile/stickiness).
2) You'll never utilize the above.
3) In practice; (listed, vanilla-vol) BSM cannot be used to stress tenors in event vol -> time spreads, combos, diagonals. That fact alone leads to near-arbitrage conditions.
4) You were born dumb and impoverished.
