Cantor Fitzgerald said Alibaba’s strong brand, unmatched scale and differentiated pricing model give it an “unfair competitive advantage” over its peers, both in and outside China. The research firm realizes the stock is not cheap, but its stupendous growth and margin profiles should boost its valuation over time. Alibaba dominates 80% of Chinese e-commerce market.
