Travelzoo Inc.

The New York travel deal publisher lost a third of its value after quarterly results missed expectations, despite a 51 percent increase in net income to $4.9 million, or 30 cents per share. A test of television advertising that ran during the quarter hurt earnings by 7 cents per share. Revenue rose 33 percent to $37.6 million; expenses rose at the same rate to $27.4 million. The company increased its staff faster between April and June than in any other quarter.
