RT Journal Article SR Electronic T1 Did the Profitability of Momentum and Reversal Strategies Decline with Arbitrage Costs After the Turn of the Millennium? JF The Journal of Portfolio Management FD Institutional Investor Journals SP 70 OP 83 DO 10.3905/jpm.2015.41.3.070 VO 41 IS 3 A1 Jieun Lee A1 Joseph P. Ogden YR 2015 UL https://pm-research.com/content/41/3/70.abstract AB This article investigates the issue of whether major developments in U.S. stock markets around the turn of the millennium reduced arbitrage costs, and consequently the profitability of momentum, long-term reversal, and short-term reversal strategies. Evidence for the years 1990 to 2013 is generally consistent with these predictions, though effects of the financial crisis of 2008 to 2009 are also evident.TOPICS: Portfolio theory, portfolio management/multi-asset allocation
