Veteran emerging markets investor Mark Mobius has named Alibaba and Tencent as key stocks in any portfolio investing in developing economies. Mobius said the Chinese technology giants "could be the foundation of any portfolio" despite recent volatility. Mobius is known for his long-term conviction picks of smaller companies, but stressed the resilience of the two Chinese tech titans. The fund manager said he likes the agility and profitability of smaller tech companies in the region but acknowledged geopolitical risks. So these companies are really very interesting companies," Mobius added.
