St. Lau et Jd. Diltz, STOCK RETURNS AND THE TRANSFER OF INFORMATION BETWEEN THE NEW-YORK AND TOKYO STOCK EXCHANGES, Journal of international money and finance, 13(2), 1994, pp. 211-222
This study examines the transmission of pricing information between th
e New York (NYSE) and Tokyo (TSE) Stock Exchanges using opening and cl
osing stock prices for seven Japanese firms. The results of this study
suggest that: (1) sample firm TSE opening returns respond to changes
in sample firm NYSE intraday stock performance, with transmission appa
rently completed at the TSE opening; and (2) sample firm NYSE opening
returns, as well as subsequent trading, respond to changes in sample f
irm TSE intraday stock performance. Taken together, the evidence repor
ted in this study is generally consistent with the notion of semi-stro
ng form market efficiency.
