(Reuters) – China’s first batch of mutual funds targeting Shanghai’s Nasdaq-style technology board have sold out quickly, reflecting keen investor interest in the sector and also raising concerns about price bubbles on the new board set to launch as early as June. Seven fund houses, including E Fund Management Co, Harvest Fund Management and China Universal Asset Management each aimed to raise up to 1 billion yuan ($148.4 million) in their newly-launched tech-focused funds, and all hit their fundraising target on the first day of sales.
