“…Research indicates that, for many economic and financial variables, a random walk is not necessarily a naïve forecast (Diebold and Lopez, 1996). This is especially true for exchange rates (Baghestani, 2009; Rossi, 2013), long‐term interest rates (Pesando, 1979; Reichenstein, 2006; Baghestani, 2008a) and stock prices (Fama, 1995). Existing evidence indicates that it is difficult for both model‐ and survey‐based forecasts of such indicators to outperform a simple random walk forecast (Meese and Rogoff, 1983; Frankel and Froot, 1987; Mitchell and Pearce, 2007; Baghestani, 2008b).…”
