This study analyses the US stock market at sector level from January 1990 to April 2013, taking into account the state of the economy. In concrete, this paper focuses on the recession periods, such as July 1990 – February 1991, April – November 2001 and January 2008 – March 2011, according to the NBER classification. Moreover, this analysis studies not only sector stock returns, but also sector trading volumes. Thus, some sectors of the US stock market show significant volatility in periods of economic turbulence, mainly during the global financial crisis (January 2008 – March 2011). In addition, this study evidences that inflation news would especially affect the US sector stock returns two days after the announcement. Lastly, according to Jareño et al. (2018), inflation announcements appear to have an impact when the state of the economy is low and when the direction of news is negative
