This paper investigates the effects of foreign exchange exposure and hedging activities on the abnormal stock price volatility surrounding quarterly earnings announcements. The findings show that abnormal volatility is positively correlated with foreign exchange exposure, suggesting that...

This paper empirically tests the random walk and efficiency hypothesis for 12 Asia-Pacific foreign exchange markets. The hypothesis is tested using individual as well as panel unit root tests and two variance-ratio tests. The study covers the high (daily) and medium (weekly) frequency post-Asian...

Sherry's (1992) nonparametric pattern tests for neural information processing are used to ascertain if the Asian FX rates followed random walks. The stationarity and serial independence of the price changes are tested on minute-by-minute data for nine Asian currencies from January 1, 1997 to...

FX pricing processes are nonstationary and their frequency characteristics are time-dependent. Most do not conform to geometric Brownian motion, since they exhibit a scaling law with a Hurst exponent between zero and 0.5 and fractal dimensions between 1.5 and 2. This paper uses wavelet...

Market microstructure and the imperfect common knowledge literature in macroeconomics both analyze the effect of dispersed information on prices. This paper draws on both sources to understand exchange rate forecasting errors. A theoretical model is developed showing that forecasting errors...
