The existence of reversal and momentum effects is confirmed by numerous empirical studies (see De Bondt and Thaler 1985; Jegadeesh and Titman 1993 for the first studies and original frameworks of the effects).

NARASIMHAN JEGADEESH and SHERIDAN TITMAN* ABSTRACT This paper evaluates various explanations for the profitability of momentum strat-egies documented in Jegadeesh and Titman ~1993!. the Jegadeesh and Titman (1993) momentum portfolio is negative, which is consistent with the behavioral theories but is inconsistent with the Conrad and Kaul hypothesis.3 Although the negative postholding period returns of the momentum port- folio appear to support the predictions of the behavioral models, further analysis suggests that this support should be interpreted with caution. This finding has been confirmed by many other academic studies, some even going back to the 19th century. When this strategy is viewed as a Firms with higher returns over the past 3- to 12- months subsequently outperform firms with lower returns over the same period.
