Two of the newsletter industry's leading growth stock advisors remain bullish on the prospects of online retailer Amazon.com (NASDAQ: AMZN), based on growth in not only online retailing but new market areas ranging from the Kindle e-reader to cloud computing.

Mike Cintolo, editor of The Cabot Top Ten Report, explains, "Amazon.com recently blew away earnings expectations." Meanwhile, Alexander Green, investment director at The Oxford Club, says, "In our view, the best lies ahead for the company." Here are their reviews.

Mike Cintolo continues, "Amazon announced that its Kindle e-book reader is now its most popular selling item, both in units and in dollars. That led to a big acceleration in revenue growth (28%, the fastest in five quarters), while earnings leaped 67%.

"Vacationers and professionals finally appear to be hitting the road, and many are relying on Expedia (NASDAQ: EXPE) to handle the details," says Nathan Slaughter in Half-Priced Stocks.

The value investor explains, "Expedia's travel sites processed 15.3 million transactions during the second quarter, 18% above the same period last year. Howevver, the gross dollar amount of those bookings dipped slightly to $5.6 billion/

"Whenever you have more trips bringing in less money, it's a pretty good indication that prices are way down.

"In a move that has long been expected, eBay (NASDAQ: EBAY) is selling Skype," reports Paul Tracy. In his Street Authority Market Advisor he reviews the deal and his bullish outlook on eBay.

"According to terms of the deal, the internet-based phone service will fall under the ownership of a private syndicate for about $1.9 billion.

"Former CEO Meg Whitman orchestrated the acquisition of Skype back in 2005 as a means of communication between buyers and sellers. And the service has attracted hordes of subscribers in a short period of time.

"Expedia (NASDAQ: EXPE) has taken flight over the past two months, soaring more than 165% off their early-March low," says Paul Tracy.

The editor of Street Authority Market Advisor explains, "Despite a sharp slowdown in leisure and business travel, overall travel volume booked through Expedia's sites (which include Hotels.com and Hotwire.com) remains impressive.

"Over the past three months, Expedia's travel sites have booked $5.2 billion (retail value) worth of travel expenditures. That gross booking figure is down about 11% over last year, but represents a considerable 30% improvement over the prior quarter.

"Google (NASDAQ: GOOG) remains the dominant search engine on the web," notes Paul Tracy. In his StreetAuthority Market Advisor, he views the stock as a solid buy for growth investors.

"In economic downturns, one of the first costs most companies cut is advertising. Not surprisingly, over the past year, most companies have slashed their advertising budgets in response to the severe economic downturn.

"But online ad spending has remained remarkably resilient. GOOG's system targets specific ads based on what users type into their search box, geographic location and other factors.

Bill Martin – well-known for his role as founder of the Raging Bull website – now shares his trading and investment advice in his always-intriguing FindProfit newsletter.

And while noting that his latest buy "strays a bit from our usual small-to mid-cap focus," he is nevertheless willing to "step up and buy web giant eBay (NASDAQ: EBAY)."

After watching EBAY for years, he says, "we believe that the stock now represents an attractive purchase for long-term investors."

Ne notes that the stock began underperforming in 2005 as growth in its core marketplace business slowed and Google gained operating steam. Meanwhile, he says, the stock is now over 20% below its 52-week high and equal to the levels it traded at in early 2004.

In his view, EBAY is now an "attractive growth at a reasonable price stock." He forecasts that the company should generate nearly $2 billion in free cash flow in 2007 despite, he notes, high levels of capital expenditures.

The advisor notes, "To us, EBAY increasingly looks like the kind of high-class company that Warren Buffett loves: it has a strong brand and franchise, it generates substantial returns on equity, it is positioned to grow for as far as the eye can see, and it is in a position to reinvest its cash flows at high rates of return."

Charles Payne, chief analyst for Wall Street Strategies, is well known from his weekly appearances on FOX TV's Bulls & Bears as well as Cashin' In, Cavuto, and FOX and Friends. And despite the sharp sell off yesterday, he remains cautiously optimistic.

He explains, "Getting investors to see the silver lining of any corrective action borders on being a Herculean task. The strange thing is that so many folks have been waiting on the sideline for the market to pull back."

Yet, he notes, when these correction do happen, investors often fail to take advantage of the lower prices. He adds, "The flip side of the nervous investors are those brave souls who want to run into a burning building." So how should an investor respond to the sharp decline?
