On the distortion of twin building lattices

We show that twin building lattices are undistorted in their ambient group; equivalently, the orbit map of the lattice to the product of the associated twin buildings is a quasi-isometric embedding. As a consequence, we provide an estimate of the quasi-flat rank of these lattices, which implies that there are infinitely many quasi-isometry classes of finitely presented simple groups. In an appendix, we describe how non-distortion of lattices is related to the integrability of the structural cocycle

Insider Trading Around Convertible Security Calls

This study examines the nature of insider trading of common stock around conversion-forcing calls of convertible securities.  Managers of call firms significantly increase their frequency of stock sales after call announcements.  Also after the call, substantially fewer call firms are classified as net buyers and a significantly greater number of call firms are classified as net sellers.  This evidence suggests that managers alter their trading behavior as though calls are associated with negative information about their firms' prospects
