We find that the order flow differential (OFD), a flight-to-quality measure constructed as the difference between large- and small-cap stock order flows, strongly and negatively forecasts output growth and interest rates in the U.S. The predictive ability of OFD for future macroeconomic fundamentals is robust to the inclusion of return factors and business cycle predictors, and it is thus a state variable candidate in the spirit of Merton (1973). Consistent with this view, we document that OFD commands a statistically significant negative risk premium in cross-sectional asset pricing tests.

We examine the effect of aggregate cash flow news and discount rate news on momentum returns. We find that momentum profits are higher following aggregate positive cash flow news, even in down markets or low sentiment periods. This finding expands on the evidence in Cooper et al. (2004) that momentum is significant only when past market returns are non-negative and in Antoniou et al. (2013) that momentum is weaker when sentiment is pessimistic. We find that the higher momentum profits during aggregate positive cash flow news periods are primarily driven by the losers continuing to underperform in subsequent periods. Our findings are consistent with the Hong and Stein (1999) model in the sense that gradual diffusion of contradictory news is accentuated when change in wealth is positive and relatively more permanent.
