Abstract

We study the effect of trading mechanisms of call auctions and continuous trading on pricing errors using data from Tehran Stock Exchange. Consistent with findings from New York Stock Exchange (Amihud and Mendelson, 1987, Stoll and Whaley, 1990), we find that pricing errors are larger at market open (which uses call auction) than market close (which is continuous trading). We investigate competing explanations for our empirical finding, and find evidence consistent with Brock and Kleidon (1992) argument that larger pricing errors at market open stem from information accumulation and lack of trading overnight, combined with inelastic demand curve for stocks.
