Abstract
Currency adjusted stock indices consider the impact of both stock value changes and underlying currency value changes on total wealth changes. This paper explores causality and cointegration of currency-adjusted indices using intraday data. This paper examines tick-by-tick data for seven currently available stock indexes, the Philadelphia Housing Index and the Dollar Index for the period 2002-2013. Results show cointegrating relationships between each combination of series examined. The analysis reveals a higher level of causality than found in previous research. The results show bidirectional Granger causality for every index pairwise combination examined.
