Topological Risk Parity
Revant Nayar, Dnyanesh Kulkarni, El Mehdi Ainasse
We develop \emph{Topological Risk Parity} (TRP), a tree-based portfolio construction approach intended for long/short, market neutral, factor-aware portfolios. The method is motiva…
High-Frequency Volatility Estimation with Fast Multiple Change Points Detection
Greeshma Balabhadra, El Mehdi Ainasse, Pawel Polak
We propose a method for constructing sparse high-frequency volatility estimators that are robust against change points in the spot volatility process. The estimators we propose are…
Twisted Nakano-Positivity of Fields of Hilbert Spaces
El Mehdi Ainasse
In a previous article (arXiv:2111.03143), we generalized Berndtsson's Nakano-positivity by retaining the same consequences under weaker hypotheses. In this article, we propose to f…
A Twisted Complex Brunn-Minkowski Theorem
El Mehdi Ainasse
In his Annals of Mathematics paper (2009), Berndtsson proves an important result on the Nakano positivity of holomorphic infinite-rank vector bundles whose fibers are Hilbert space…
