“…For example, Amin and Lee (1997), Easely, O'Hara, and Srinivas (1998), Chakravarty, Gluen, and Mayhew (2004), Stoll and Schlag (2005), Cao, Chen, and Griffin (2005), Pan and Poteshman (2006), and Kang, Lee, and Lee (2006) provide evidence that information flows from option markets to cash markets, while Bhattacharya (1987), Stoll and Whaley (1990), Booth, So, and Tse (1999), Chiang and Fung (2001), and Chan, Chung, and Fung (2002) see no evidence of this. This paper revisits the issue because we have access to a new dataset that promises new insights.…”
