Multifactor models of momentum portfolios on the Warsaw Stock Exchange, 1999-2009
We have computed selected portfolio factor returns for the stocks listed on the WSE over the 1999-2009 period. There is a size premium on the WSE, while the size and sign of the value premium depends on the value factor used. Investors also seem to put a premium on corporate liquidity. Top momentum deciles as well as the momentum factor exhibit on average positive returns. Further, we tested a number of multifactor models of momentum portfolios. It appears that the SP factor based on the Sales/Price relative valuation of stocks has some power in explaining the momentum returns. Further testing of this and other factors introduced above, EP, CP and STI seems desirable. (original abstract)
