comment Finding historical data for indices
Absolutely agreed. I don't know how many Ph.D. students there are in your institution, but it definitely takes a few in the department to justify the purchase. Just as a nice resource, here is the collection of interesting papers: optionmetrics.com/research.html

@berkobay, it's either affordable or quality :). As an academic, you can check if your university is subscribed to OptionMetrics.

comment Constructing Volatility Smile from Implied Volatility & Delta
The spot price is publicly available on yahoo/google finance or even the company website. One can back out the strikes and then plot the smile using strikes on X-axis and implied vol on Y-axis.

comment Implied dividend estimation
It's the PV of the entire stream. P.S. I'm working on revised model, this one uses one day of data and introduces a lot of noise. It would be better to regress from approx 90 days set of ATM options.

comment VSTOXX Implied Volatility Calculation
@MattWolf, it's not unusual for vol-of-vol options to reach these levels of implied vols, especially for near term expiration (note that the first chart is 30 days.) Longer term options (180-220 days) reach 45%-50%. Take a look at Brenner et al. specifically p.29 "Time series of VIX options implied vol": fma.org/NY/Papers/The_Term_Structure_of_VIX.pdf I'd love to hear your insights.

Matt, I implemented both models and there are interesting and useful results. If you ever think about trading VSTOXX, there is already implemented and calibrated model.

comment VSTOXX Implied Volatility Calculation
I'll see the results, of course, but it's a great start. I also wonder what is the industry consensus in this respect. Hopefully, we will see more activity/voting in this thread.
