It helps explain why stock prices may deviate from the expected fundamental values, and how speculators can make profits from stock price manipulations provided the presence of informational frictions. An empirical wavelet analysis of stock market comovements reveals some features of the informational spillovers from NASDAQ and S&P500 to some Eastern Asian markets.
