Comparing the market microstructure between two South African exchanges
Ivan Jericevich, Patrick Chang, Tim Gebbie
We consider shared listings on two South African equity exchanges: the Johannesburg Stock Exchange (JSE) and the A2X Exchange. A2X is an alternative exchange that provides for both…
The Epps effect under alternative sampling schemes
Patrick Chang, Etienne Pienaar, Tim Gebbie
Time and the choice of measurement time scales is fundamental to how we choose to represent information and data in finance. This choice implies both the units and the aggregation…
Fourier instantaneous estimators and the Epps effect
Patrick Chang
We compare the Malliavin-Mancino and Cuchiero-Teichmann Fourier instantaneous estimators to investigate the impact of the Epps effect arising from asynchrony in the instantaneous e…
Detecting discrete processes with the Epps effect
Patrick Chang, Etienne Pienaar, Tim Gebbie
The Epps effect is key phenomenology relating to high frequency correlation dynamics in financial markets. We argue that it can be used to provide insight into whether tick data is…
Malliavin-Mancino estimators implemented with non-uniform fast Fourier transforms
Patrick Chang, Etienne Pienaar, Tim Gebbie
We implement and test kernel averaging Non-Uniform Fast Fourier Transform (NUFFT) methods to enhance the performance of correlation and covariance estimation on asynchronously samp…
