Just days after nearly hitting a new all-time high, shares of Amazon (AMZN) are faltering ahead of its earnings report, due after the bell Tuesday.
That begs the question: What do investors know that the rest of us don't? Probably not much, but the stock decline may be signaling some jitters.
Shares were down more than 2% Tuesday.
It's not too big a stretch for investors to be a little on edge, given Amazon's less-than-stellar third-quarter report.
This time around, analysts are anticipating a strong quarter, led by a 28% jump in revenue. That may sound pretty solid but some, like JPMorgan, are lowering their expectations for holiday sales "to reflect good (but not great) U.S. e-commerce trends during the holiday."
Did you buy a Kindle this year?
And while BGC Partners tech analyst Colin Gillis is hopeful Amazon will turn a profit, he's keeping a "hold" rating on the stock and says he prefers eBay (EBAY).
StockTwits traders weighed in with their own expectations.

Haha . Good one. People always care about profit, but they also like their new shiny gadgets. Stay tuned for Amazon -- only 5 hours to go.
Barnes & Noble is having a good end to the year, thanks to the gift that keeps on giving -- the Nook.
British book publisher Pearson (PSO) said Friday that it would pay nearly $90 million in cash for a 5% stake in Barnes & Noble's Nook division. Microsoft (MSFT) already owns a 16.8% stake, leaving Barnes & Noble with 78.2%.
That was enough to offset any disappointment over Barnes & MORE
