Alibaba Group Holding Ltd (BABA - Get Report) investors demand wider spreads on the Chinese e-commerce giant's notes than they do for U.S. competitors eBay Inc (EBAY - Get Report) and Amazon.com (AMZN - Get Report) despite the companies' comparable credit ratings, Bloomberg reported.

This signals a good opportunity to buy Alibaba bonds, Bank of America/Merrill Lynch (BAC - Get Report) reported in a note, especially given the company's stellar second quarter results reported last week.

The analysts, who rate Alibaba stock "overweight," said they expect the company's bond premiums will gravitate closer to those of its U.S. peers soon.

Alibaba stock traded up about 0.6% premarket Tuesday to $170.25. It's soared nearly 93% since the start of the year.
