“…While, the general belief is that oil and stock prices are leading indicators of the economy, there is ample evidence that economic activity too plays a crucial role in predicting both in and out-of-sample movements in oil (see for example, Kilian (2009), Kilian and Vigfusson (2013), Kilian (2014, 2015) and Baumeister et al, (2015)) and stock prices (see for example, Rapach, Wohar and Rangvid (2005), Goyal and Welch (2008), Rapach, Strauss and Zhou (2010), Rapach and Zhou (2013)).
