“…We follow Bessembinder and Zhang (2013) and implement a regression model to investigate the effects of firm characteristics on the long-run stock returns of our sample groups from Table 1 from March 2000 until December 2012. We consider nine characteristics that have been shown to be associated with average stock returns: market Beta (Sharpe, 1964;Lintner, 1965;Mossin, 1966), size (Banz, 1981), book-to-market (Rosenberg, Reid and Lanstein, 1985), momentum (Jegadeesh, 1990;Lehmann, 1990;Jegadeesh and Titman, 1993;Chan, Jegadeesh and Lakonishok, 1996;Novy-Marx, 2012), illiquidity (Amihud, 2002), gross profitability (Novy-Marx, 2013), investment (Aharoni, Grundy and Zeng, 2013), idiosyncratic volatility (Goyal and Santa-Clara, 2003;Bali, Cakici, Yan and Zhang, 2005;Zhang, 2006, 2009;Chen and Petkova, 2012), and expected idiosyncratic skewness (Boyer, Mitton and Vorkink, 2010). Due to the high IPO activity among Internet and technology stocks, many of our sample firms have only short histories of prices and fundamentals at the start of our sample period in March 2000.…”
