Uber, Alibaba, Nvidia: CNBC’s Halftime Report traders answer your questions

CNBC's "Halftime Report" traders answered questions from CNBC Pro subscribers, including their views on Uber and Nvidia, and what to do with Alibaba amid the tech crackdown in China.

Shannon Saccocia, chief investment officer at Boston Private, said Alibaba is a long-term buy given that it's the biggest e-commerce provider in China and the only major cloud provider in the country. But she cautioned about the volatility in the short run.
