ChannelAdvisor December Data Implications For

| About:, Inc. (AMZN)

ChannelAdvisor has again reported "same-store sales" for December 2013. In what concerns (NASDAQ:AMZN) the data was as follows:

Amazon - Amazon's December came in at 27.9% compared to November's 12.3%, a substantial m/m increased caused by the holiday shift.

The distortion due to thanksgiving falling in a different week this year was significant, leading to very low November growth which was at least partially compensated in December. Still, we can draw some insights from how the entire Q4 2013 quarter went. This is how the average growth reported by ChannelAdvisor stood after we plug in December:

So again, saw yet another 380 bps deceleration in the December quarter.

Modeling's Q4 2013 revenues

ChannelAdvisor is our best guess for how did during the quarter. There is a significant correlation between the average same-store sales growth reported by ChannelAdvisor and's overall revenue growth rate year-on-year for the same quarter. This correlation shows a R2=0.88, though down slightly from an R2 near 0.90 2 quarters ago.

This correlation seems to be slightly lower now because's overall growth rate is being helped by an accounting change. is supposedly now accounting for ebook sales using an wholesale model whereas the same ebooks were booked under an agency model last year. This means that the same ebook sales produce around 3 times more revenue, and with ebooks being "multi-billion" segment, this has significant impact on the overall growth rate.

That said, this is how a plot of the ChannelAdvisor and's overall revenue growth rate data looks like:

I painted the 2 last quarters which were already influenced by the ebook accounting change in red. The orange dot represents the best fit for Q4 2013. So what does it imply?

The 21.3% growth rate reported by ChannelAdvisor implies 17.9% growth for's overall revenues in this quarter. This compares with the consensus expectation of 22.5% growth. The consensus expectation is for $26.06 billion in revenues. The revenues implied by this model are $25.08 billion.

With no other factors in play, this would mean was likely to miss revenue estimates significantly. But the same could already be said of last quarter, and it turned out beat expectations.

For this quarter, we again have 2 major effects which will help's revenues, if not its profits, these are:

  • The ebook accounting change, which is now near its largest possible impact on revenues. The massive impact from this accounting change might be enough to drive revenues from the model's 17.9% expected growth rate all the way up to the 22.5% consensus revenue growth rate;
  • And the new generation gaming consoles (Xbox One, PS4), which are selling very well and might add something along the lines of 2% to's quarterly growth rate.


Structurally, continues to slow down. Yet, in a way that would be allowed to no other stock, is allowed to run free with a significant accounting change causing reported growth rates to be higher than they would otherwise be. At this point this is allowed both by the analyst community and by the SEC.

Given this constraint, while the strong correlation between ChannelAdvisor data and's overall revenue growth rate would dictate that would miss revenue projections significantly, the truth is that the most likely scenario is for to meet those projections.

On the other hand, this has no implications for's profitability. These are accounting-related revenues with no calories. This means that it continues to be likely that will guide down EPS for Q1 2014. As for Q4 2013, expectations have been cut so much that I no longer have an opinion (I find the new expectations possible to be met).
