Shanghai-HK link set to boost arbitrage gains for investors

Arnout van Rijn cannot resist a good arbitrage opportunity.

The chief investment officer in Hong Kong for Robeco, whose Asia-Pacific stock fund beat 92 percent of peers in the past three years, said he has wagered on narrowing price gaps involving dual-listed stocks in Thailand, South Korea and Singapore during a more than 20-year career managing money.

He has now turned to China, where equities traded on the mainland are valued at the biggest discounts since 2006 versus their counterparts in Hong Kong.
