Abstract: The purpose of our thesis is to build a contrarian trading strategy that would maxi-
mize growth rate of our wealth. In the rst part, we derive the strategy by algebraic
means. In particular, we exploit that growth maximization is equivalent to period by
period maximization of log wealth. We approximate the log optimal portfolio by a
mean-variance ecient portfolio and specify the rst and second conditional moment
by a dynamic econometric model. In the second part, we discuss de ciencies of our
strategy and use Monte Carlo simulations to create a modi cation that should per-
form better. In the nal part, we demonstrate viability of the strategy on historical
data. Assuming unlimited leverage and mild transaction costs, the strategy was able
to generate annual geometric mean return close to 24%
