Tokyo investors are likely to be cautious this week about a possible market downturn, analysts said, while political developments in Japan will be a focus ahead of an election next month, Arab News reported. “The market continues to show all the signs of being technically overbought and potentially ready for a pullback,” said Masayuki Doshida, senior market analyst at Rakuten Securities. Japanese Finance Minister Taro Aso said the yen’s steep slide over the past week had been “too fast.” Prime Minister Shinzo Abe has dissolved the lower house of parliament as he prepares for an election he called for next month after Japan’s economy sank into recession.
