Chinese investors are piling into foreign assets, especially U.S. stock funds, after regulators lifted outbound quotas, unlocking pent-up demand as domestic yields are at rock bottom and Beijing tightens unofficial routes for moving money abroad.

Late last month China's foreign exchange regulator raised the outstanding Qualified Domestic Institutional Investor quota by $6.8 billion to a record $183 billion.
