Simple models have underestimated drawdown risk in equities, low volatility equities, and income strategies, and overestimated historical drawdown risk in
  • Making Python massively parallel (and burgers) [Cuemacro]

    I like burgers. I suspect I start most of my blog articles with a similar sentence. Most burgers are sufficiently large, such that a single burger will suffice for a meal. However, occasionally you get burger sliders, mini burgers of different flavours, which are also easier to share. It is an obvious point that a plate of burger sliders is likely to end up getting finished quicker than a single
  • Modeling Volatility and Correlation [Jonathan Kinlay]

    In a previous blog post I mentioned the VVIX/VIX Ratio, which is measured as the ratio of the CBOE VVIX Index to the VIX Index.
