  • Czekanowski Index-Based Similarity as Alternative Correlation Measure [Quant at Risk]

    In quantitative finance we are used to measuring direct linear correlations or non-linear cross-bicorrelations among various time-series.

This is true if the the data follow Gaussian distribution. In other case, the rank correlation
  • Realized Volatility In Bitcoin Index [Lucas Miranda]

    One of the most relevant characteristics of digital assets is the high volatility observed in their prices. In this context, it is necessary that we have an adequate estimate of this parameter.

    What is the role of factors in asset allocation? Should investors substitute factor exposures for asset classes in constructing strategic portfolios?

  • A New parameterization of Correlation Matrices [Eran Raviv]

    In volatility modelling, a typical challenge is to keep the covariance matrix estimate valid, meaning (1) symmetric and (2) positive semi definite*. A new paper published in Econometrica (citing from the paper) introduces a novel parametrization of the correlation matrix. The reparametrization facilitates modeling of correlation and covariance matrices by an unrestricted vector, where positive

  • Deep neural networks, gradient-boosted trees, random forests: Statistical arbitrage on S&P 500 [Enjine]

    Although Harry Potters world of magic exists on the same earth as our magic-less Muggle world, the worlds might as well be on different planets.

In academia, a persons work is judged by its logical rigour. In

  • Pairs Trading with Markov Regime-Switching Model [Hudson and Thames]

    Traditional pairs trading strategies are prone to failures when fundamental or economic reasons cause a structural break and the pair of assets that were expected to move together are no longer having a strong relationship.

The MAD code in C for Zorro: var MAD(vars Data, int ShortPeriod,
