“…Return volatility ( RVOL ) is measured by the standard deviation of daily stock returns (Roulstone, 2003; Iskandrani, 2016; Ajina and Habib, 2017; Al-Jaifi, 2017; Al-Jaifi et al , 2017; Gajewski and Li, 2015). This variable reflects information uncertainty or risk in the capital market (Yoon et al , 2011; Loukil and Yousfi, 2012; Iskandrani, 2016; Gajewski and Li, 2015). Most studies show that high volatility stocks are riskier and, consequently, less liquid (Dumontier and Maghraoui, 2006; Ben Saada et al , 2010; Ajina et al , 2015; Al-Jaifi, 2017).…”
