Building Models to Fix Mistakes of the Past

Featuring Emanuel Derman

Emanuel Derman is one of the true innovators of quantitative finance and the author of My Life as a Quant and Models Behaving Badly, meets with Michael Green to discuss a model driven world and the future of equity derivatives. In an intense discussion on the ability to price volatility it is argued that unlike in science, models can never provide the ultimate truth because they are always tackling the problems that the previous set of models created. Filmed on August 29, 2017, in New York.

    Nice observation by Green re optionality in value equities. So true in practice.

    I'm getting to me a real Michael Green fan. We are so lucky to have access to him through RV TV along with Grant and Raoul. Um...stability ultimately leads to instability---wasn't that the thesis of...
    Oh some Economist a few decades ago (smile). How many more sell Vol carry traders are left?....and what happens when we run out of them?...just leverage the trade infinitely?

    More like this. Excellent, both by Mike and Mr. Derman. My only criticism: i think Mike has to focus a little more on teasing out insights from the interviewee - a little too much from him.

    No, theories started with a discussion with Mark Rubinstein (as in Cox-Rubinstein) in 2006, implemented in 2009. Sam Wilderman at GMO independently proposed in 2011 (https://es.scribd.com/mobile/document/73200528/ReThinking-Risk-What-the-Beta-Puzzle-Tells-Us-About-Investing-GMO) which is where Kaleidoscope lifted without attribution

    Mike is great, indeed. But I wanted to listen to Derman just a tad more extensively.

    Wow - the number of times Derman said to Mike Green, "that's very insightful" or "clever way of looking at it." We are privileged to listen to a man as intelligent as MG. And the biggest take-away for me is that now I know why MG is so damn smart -- he wanted to be a Physicist! ; ) And on a more serious note, so true that backward looking models will by definition never give us a solid view of the future...but my contention is that this is where human judgment is so vitally important.

    Wow, just fantastic! As others have said it would be just great to get a 3-way conversation going with Mike, Emanuel and Nassim Taleb and let them talk for a couple of hours. What a dream segment (can it happen???).
