Comtec Solar Systems Group, which makes monocrystalline solar wafers, yesterday failed to impress investors with its trading debut, with its shares falling 5.7 per cent below the offer price of HK$2.10 to close at HK$1.98. The Shanghai-based firm, which revived its initial public offering this year, raised HK$525 million after setting its offer price at the bottom of its HK$2.10 to HK$3.10 range. Analysts said investor confidence in new shares had been shaky because of poor trading debuts from recent large offerings such as Metallurgical Corp of China. Comtec hit a high of HK$2.22 shortly after the opening before its decline. 'A lot of investors will dump their shares if they sense things are not going well,' said Steven Leung Wai-yuen, a director of institutional sales at UOB Kay Hian. 'Investors will only hold on to those that have good medium to long-term outlook in earnings.' However, analysts expect a better uptake for China Minsheng Banking Corp's HK$30 billion offering. The company will kick off its roadshow on November 9, according to Reuters. 'Investors [want] quality bank stocks and Minsheng will emerge as a nice pick,' said Mark To, an associate director at Prudential Brokerage.
