Despite a massive sell-off of stock across the region early in the week, Bank of China (BOC) was expected to price its IPO towards the top end of the range. BOC's IPO was at least 70 times oversubscribed on Tuesday, the Financial Times reported, and the bank was still counting subscription forms from small investors. The strong interest in the IPO, which may become the largest in Hong Kong history, was not affected by massive sell-offs in stock markets around the world. BOC is selling 25.57 billion shares at HK$2.5-3 (US$.32-.38) each and is due to make its trading debut on Hong Kong's main board on June 1. If priced at the top end of the range, the shares will trade at 2.2 times book value.
