Abstract
This paper uses monthly data from Jan 2002 to Sep 2022 from fifty top Software companies of 2022 rated by the Software Report to examine the existence of momentum and reversal effects both in short term and long term in Software industry. The relationship between investment sentiment and anomalies is further explained and the robustness of FF-3F Model is tested. Based on two ways of forming portfolios, equal-weighted portfolio and value-weighted portfolio, the result shows that the software industry has stronger momentum and reversal effects in the medium term and short term. The Mkt-RF factor in CAPM and FF-3F model explain the momentum and reversal effects better for software industry in the short run, and HML factor explains better in the long term. Value weighted portfolio is better on explaining these effects. It is better not to utilize long term investment strategy and investors are preferring value stocks in Software industry.
