The empirical results indicate that among the 15 targets investigated in this study, SVI showed the price discovery function for only United Microelectronic Corporation (2303) and Foxconn Technology Group (2317); the remaining targets display no significant change in price discovery because of an increase in investor searches. Therefore, in the Taiwanese market, SVI has no significant function in triggering price discovery between stock prices and their implied price.
