Are benefits from oil - stocks diversification gone? New evidence from a dynamic copula and high frequency data [PDF]
, 2015 Oil is perceived as a good diversification tool for stock markets. To fully understand this potential, we propose a new empirical methodology that combines generalized autoregressive score copula functions with high frequency data and allows us to ...
