We provide an improved measure of opinion divergence constructed from the dispersion of order flow across Nasdaq market makers that captures the breadth of divergence that is lost by volume-based measures. We find evidence that both limited participation (in the form of delayed price reaction and short sale constraints) and divergent opinions contribute significantly to drift. We also find that earnings surprises induce permanent upward shifts in opinion divergence, trading volume, and return volatility that last up to nine months following the announcement. Our results suggest that opinion divergence elicits added risk in the form of increased volatility with the resulting returns comprising a component of drift. We document that daily opinion divergence is a priced risk factor over the nine month drift period. The persistence of these relationships suggests that opinion divergence represents a fundamental change in the market's assessment of the announcing firm that extends beyond the announcement period and influences post-announcement stock returns.
