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.

$AMZN ugly reversal from 285 area and now #earnings are a total gamble - #traders always have an edge - live to #trade another day #stocks
Couldn't have said it better myself. But then again, isn't all trading kind of a gamble? Welcome to the casino of Wall Street.
Good point TrendHunter.
Barnes & Noble (BKS) took a hit from sluggish Nook sales so it's little wonder there may concern about how many of those sales shifted to the Kindle, if any. By all accounts, it was a relatively modest holiday season for retailers overall, both online and traditional.

Need I say more? I'm not sure Amazon will have quite the sharp sell-off that Apple did but then again, who knows? Investors are a fickle bunch and if the news is really disappointing, they may opt to bail out.
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.
Auction site eBay continues to impress investors, thanks in large part to the ongoing success of PayPal.
Late Wednesday, eBay reported better-than-expected earnings and revenue for its latest quarter. And while the company issued slightly weaker guidance for the current quarter, its full-year outlook was rosier.
Shares of eBay (EBAY) rallied nearly 4% to a new 52-week high Thursday. The stock has been on a tear, soaring 41% over the past MORE

Call them the dot-com survivors.
AOL (AOL), Amazon.com (AMZN), eBay (EBAY), Priceline (PCLN) and Yahoo (YHOO) were all major players at the height of Internet insanity in the late 1990s. They are all still around today MORE

Cyber Monday has been good to eBay.
Shares of the auction site hit a 52-week high Thursday, just days after logging strong gains on one of the most important online shopping days of the year for retailers.
It's not just online shopping that's attracting consumer interest. All in all, it looks like consumers are increasingly getting more comfortable with paying for their purchases on mobile devices.
eBay (EBAY) also got a boost MORE

More people are hitting the eBay auction block to buy and sell their wares, and they're using PayPal to complete those online transactions.
EBay (EBAY) reported third-quarter earnings per share that beat Wall Street estimates by a penny and said they have 14% more active users over last year.
Investors said buy, buy, buy to the stock Thursday, sending its shares up more than 4%. Several Wall Street analysts did too.

Mobile payments seems to have replaced social as the tech phenomenon that everybody is talking about. Privately held Square made waves with its groundbreaking deal a few weeks ago with coffee king Starbucks (SBUX). Wal-Mart (WMT), Target (TGT) and several other prominent retailers have teamed up to create the Merchant Customer Exchange. And Google (GOOG) has big financial and wireless firms such as Citigroup (C), MasterCard (MA) and Sprint (S) MORE

Shares of eBay rallied nearly 10% Wednesday, hitting their highest level since January 2006, after the company topped earnings and sales expectations for the second quarter.
eBay (EBAY) CEO John Donahoe credited the solid performance to the successful turnaround of the company's e-commerce business, called eBay Marketplaces.
Revenue for e-commerce business jumped 9% from a year earlier to a record high of $1.8 billion.
eBay's PayPal unit also continued to post strong results, MORE

#StupidStock Move of the Day! $EBAY is down more than 6% on no news & big volume. Do people really think Europe is hurting PayPal that much?— Paul R. La Monica (@LaMonicaBuzz) May 30, 2012
Yes, a slowdown in Europe won't be great news for eBay (EBAY). But don't we already know that eBay, like nearly every consumer-centric company, will face economic headwinds? Isn't that already priced into the stock, which MORE

Tiffany (TIF) is showing that diamonds are not an investor's best friend. And eBay's (EBAY) deal to get PayPal to be used on VeriFone Systems (PAY) cash registers gets little love from traders.
etfhack: @Retail_Guru $TIF inventories up 27%? how can this not bode horribly for margins in back 1/2 of yr?
firstadopter: $TIF PR: "Americas region underperformed, continuing a soft trend that began in the last quarter of 2011" Wow they MORE
