"It looks like companies are going to lean towards cutting their forecasts if anything, with the yen as it is," he added.
Many companies factored in an exchange rate of about 80 yen to the dollar during the last earnings season, but the Japanese currency has stayed robust as a "safe haven" for investors, eroding erode revenues earned abroad. The yen hovered around 78.29 to the dollar on Tuesday morning.
