History Chen, Roll, and Ross (1986): Macroeconomic developments are undiversified risk within the APT framework and hence merit excess returns. However, economic theory does not determine which economic variables are responsible for excess returns. Influential works: Balduzziet al (2001); Flannery & Protopapadakis (2002); Andersen et al (2003); Hautsch & Hess (2007); Gilbert et al (2010); Evans (2011).

Specifics of This Work Details in http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2364077 Time period: January 2009 - July 2013 18 major macroeconomic indicators Equity ETFs: : S&P 500 SPDR (SPY), Financial Select Sector SPDR (XLF), Industrial Select Sector SPDR (XLI), and Consumer Discretionary Select Sector SPDR (XLY). The autoregressive model includes both the announcement event factors (dummy variables) and the announcement surprise factors. The latter are proportional to the difference between the announced and expected macroeconomic indicator values. Volatility is accounted by the GARCH process.
