“…Even though domestic investors were allowed to trade B-shares after 2001, there is still some degree of segmentation between the A- and B-share markets in China. This is consistent with Ahlgren et al (2009) in which they find that A- and B-shares are cointegrated, but not for all firms. Similarly, Qiao et al (2008) finds a fractional cointegration between Chinese A- and B-shares after the relaxation of restrictions on the purchase of B-shares by domestic residents.…”

“…We know that the B-index is determined by the B-share trading, whereas the A-index is determined by A-share trading and the composite index is determined by both A- and B-share trading. The difference between A- and B-share trading has been discussed in the literature, such as Chan et al (2007, 2008), Ahlgren et al (2009) and Schuppli and Bohl (2010). By studying A- and B-share trading and comparing the price discovery role of the two segmented markets, they find that there exists information asymmetry between A-share traders and B-share traders.…”

“…As noted in Ahlgren et al (2009), greater co-integration between tradable A-and B-share prices is evident in issuers with a lower proportion of non-tradable stock. Based upon this insight, we make specific control for the cross-sectional average percentage of non-tradable stock outstanding.…”

“…Lee, Rui, and Wu (2008) find that the B-share discounts declined substantially after the lifting of restrictions on foreign ownership in China. Ahlgren, Sjo, and Zhang (2009) find that the A-share premia are nonstationary, and that the A-and B-share prices are not cointegrated up till January 2001. After February 2001, when domestic investors were allowed to trade B shares, the A-share premia become stationary and the A-and B-share prices cointegrated.…”
