Travelzoo ( TZOO) has gone from Wall Street hero to zero again. Shares of the online travel publisher plunged 14% after it reported disappointing second-quarter results. That was the biggest loss in Travelzoo shares since April. Travelzoo, publisher of a newsletter that lists travel deals, said net income rose 77% to $3.9 million, or 23 cents a share, from the year-ago $2.2 million, or 12 cents. Sales rose 42% to $17.4 million. Results beat the 21-cent consensus estimate of analysts surveyed by Thomson Financial but trailed the $17.6 million revenue forecast. Four analysts officially cover the stock. "From now until the end of time, a growth stock that beats on EPS and misses on revenue will go down," says Wedbush Morgan analyst Bill Lennan, who rates the shares as a hold. He cut his price target from $35 to $30. The stock, which traded at $110 in December 2004 and more than doubled in a brief span earlier this year, is a favorite of short-sellers. They control about 24% of its float, according to Bloomberg data. Shares of Travelzoo have jumped more than 30% this year, outperforming such Internet titans as Google ( GOOG), Yahoo! ( YHOO) and eBay ( EBAY). "I talk to customers and they love the product," Lennan says. "The fundamentals are outstanding."
