Finding an optimal balance between risk and returns in investment portfolios is a central challenge in quantitative finance, often addressed through Markowitz portfolio theory (MPT…
A Larger Extent for the Ophiuchus Stream
N. Caldwell, A. Bonaca, A. Price-Whelan +2
We present new kinematic data for the Ophiuchus stellar stream. Spectra have been taken of member candidates at the MMT telescope using Hectospec, Hectochelle and Binospec, which p…
Inventory effects on the price dynamics of VSTOXX futures quantified via machine learning
Daniel Guterding
The VSTOXX index tracks the expected 30-day volatility of the EURO STOXX 50 equity index. Futures on the VSTOXX index can, therefore, be used to hedge against economic uncertainty.…
On the use of field RR Lyrae as Galactic probes: I. The Oosterhoff dichotomy based on fundamental variables
M. Fabrizio, G. Bono, V. F. Braga +21
We collected a large data set of field RR Lyrae stars (RRLs) by using catalogues already available in the literature and Gaia DR2. We estimated the iron abundances for a sub-sample…
Two chemically similar stellar overdensities on opposite sides of the plane of the Galaxy
Maria Bergemann, Branimir Sesar, Judith G. Cohen +9
Our Galaxy is thought to have undergone an active evolutionary history dominated by star formation, the accretion of cold gas, and, in particular, mergers up to 10 gigayear ago. Th…
Statistical properties of market collective responses
Shanshan Wang, Sebastian Neusüß, Thomas Guhr
We empirically analyze the price and liquidity responses to trade signs, traded volumes and signed traded volumes. Utilizing the singular value decomposition, we explore the interc…
