In this project, we consider a class of generalized Kyle-Back strategic insider trading models
in which the insider is able to use the dynamic information obtained by observing the instan-
taneous movement of an underlying asset that is allowed to be inuenced by its market price.
Since such a model will be largely outside the Gaussian paradigm, we shall try to Markovize it
by introducing an auxiliary (factor) di usion process, in the spirit of the weighted total order
process, as a part of the \pricing rule". As the main technical tool in solving the Kyle-Back
equilibrium in such a setting, we study a class of Stochastic Two-Point Boundary Value Prob-
lem (STPBVP), which resembles the dynamic Markov bridge in the literature, but without
insisting on its local martingale requirement. In the case when the solution of the STPBVP
has an a ne structure, we show that the pricing rule functions, whence the Kyle-Back equi-
librium, can be determined by the decoupling eld of a forward-backward SDE obtained via a
non-linear ltering approach, along with a set of compatibility conditions. This is a joint work
with Jin Ma.
