0508 GMT - Japanese stocks look attractive, especially when the dollar is trading above 152 yen, T. Rowe Price's David Clewell says in a note. The 152 yen level is significant because it is broadly in line with the foreign-exchange assumption found in the Bank of Japan's tankan quarterly survey for Japanese companies, says Clewell, a portfolio manager. He says when the yen is weaker than that level, that can support upward earnings revisions for Japanese exporters. The Nikkei Stock Average is 1.0% lower at 68263.54. The dollar is at Y157.82.
