In a competitive information market, a single information source can only dominate other sources individually, not collectively. We explore whether earnings announcements constitute such a dominant source using Ball and Shivakumar’s (2008) R metric: the proportion of the variation in annual returns explained by the four quarterly earnings announcement returns. We find that the earnings announce...

Abnormally high net insider selling is commonly observed after repurchase tender offer (RTO) announcements although, on average, firms experience positive abnormal returns in the years after the repurchases. We explore two potential explanations: liquidity trade timing and informed trading. Consistent with the notion that fixed price RTOs are more likely than Dutch-auction RTOs to signal underv...

1. Let M be a connected, orientable, triangulated 3-manifold and let A(Zw2(M) be a sub-group which is invariant under the operators in 7Ti(il/f). By a Ti(M)-class in 7r2(.M) we mean the set of elements ±£a, for some a£7r2( if) and every %ÇÎTI(M). The invariance under 7Ti(M) means that, if a £ A , then the entire 7Ti(Af)-class {+£#} is contained in À. A wi(M)-class is represented by a map 5—»M",...
