Abstract: As a consequence of the AdS-CFT correspondence, planar ${\cal N} =4$ superYang-Mills SUN theory is expected to exhibit stringy behavior and multi-Reggeasymptotic. In this paper we extend our recent investigation to consider issuesof analyticity, a central feature of Regge asymptotics. We contrast flat-spaceopen string theory in the planar limit with the ${\cal N}=4$ super Yang-Millstheory, as represented by the Bern, Dixon and Smirnov \cite{Bern:2005iz} BDSconjecture for n-gluon scattering, believed to be exact for $n=4,5$ andmodified only by a function of cross-ratios for $n\geq 6$. It is emphasizedthat multi-Regge factorization should be applied to trajectories with definitesignature. A variety of analyticity and factorization constraints realized inflat space string theory are not satisfied by the BDS conjecture, at least whenthe exponential factors are truncate in the infra-red regulator below$O\epsilon$.
