Shares of BoC Hong Kong (Holdings) ended their second day of trading higher after underwriters again supported the faltering issue. The Hong Kong subsidiary of the Bank of China closed the day up 1.86 per cent at HK$8.25 after falling as low as HK$8 early in the session. The stock debuted on Thursday at HK$8.50, the same as its initial public offering price, and fell 4.7 per cent to HK$8.10. Brokers said the bank's underwriters were doing much of the bidding, with Goldman Sachs' offers supporting the price above HK$8 in the morning session and BOC International taking over the reins in the afternoon. An over-allotment option gives underwriters the right to buy up to 15 per cent of the flotation shares in the market. One analyst estimated about 80 per cent of buy offers for the day came from BOC International. Stabilisation measures may continue next week. The company was also given a boost after Morgan Stanley Capital International said the company would be included in its Hong Kong index at the close on August 30.
