Alibaba shares are getting slammed after this weekend's brutal report in Barron's

Alibaba shares are down 4% in early trading on Monday after this weekend's brutal report in Barron's.

At below $62 per share, Alibaba is at a new all-time low.

The latest leg lower comes after Jonathan Laing in Barron's this weekend published a 3,000-word takedown of the Chinese e-commerce site that questioned the integrity of its financial statements, the company's growth trajectory, and argued that Alibaba shares could fall 50% from current levels.

Alibaba, of course, disagreed, and on Sunday followed with a lengthy response, going through Laing's argument on an almost point-by-point basis, adding that the story, "lacks three key ingredients - integrity, professionalism, and fair play."

In a note to clients on Monday, SunTrust analyst Bob Peck - who has a "Buy" rating and $100 price target on shares of Alibaba - said that while the Barron's report "raised several fair issues...we think several other negative points were overstated/misconstrued."

Of course, whether or not you think Barron's is right or wrong, ahead of this report Alibaba shares have been absolutely brutal in 2015, falling more than 35% year-to-date through Friday.

This Friday will mark the 1-year anniversary of Alibaba's public debut when shares priced at $68 and rose 38% in their first day of trading. After topping out near $120 per share in November 2014, shares are now near $64.

Here's the ugly year-to-date chart.
