Upon Further Review:

Amazon.com: The shares of Amazon.com (NASDAQ:AMZN) are up more than three percent this afternoon following news that the company's board has approved the buyback of $500 million worth of its common stock within the next 24 months. Despite this good news, the stock is having some trouble tackling the 29 level. This area marked an intraday high for the shares on July 26 when they gapped sharply lower. In fact, this region has hindered the equity's rally attempts since the significant gap. Furthermore, the security is seeing some heavy call trading at the 30 strike, which could add yet another layer of potential resistance. In the September series, more than 8,000 calls have accumulated at the 30 strike, and volume currently numbers more than 1,500 contracts, making it the most-active call for AMZN.

eBay and Google: This morning, Google (NASDAQ:GOOG) announced that it will have exclusive rights to display text ads on eBay's (NASDAQ:EBAY) auction web sites outside the U.S. The two companies will begin testing the arrangement early next year, and also plan to cooperate in developing click-to-call initiatives, which enable consumers to call merchants and advertisers directly using connections displayed in the ads.

Technically speaking, EBAY has been steadily guided lower by its descending 80-day moving average. Meanwhile, GOOG isn't looking much better. The stock is currently trapped between support in the 365-375 region and resistance at its declining 10-day and 20-day moving averages. What's more, GOOG has made a series of lower highs since the beginning of the year and is poised to log its second consecutive monthly close below its 10-month moving average.

Travelzoo: Travelzoo (NASDAQ:TZOO) is at it again. The shares are up more than eight percent this afternoon on no news. However, this rally is looking extremely familiar to when it climbed to resistance at the 36 level and was ultimately rejected. The stock has tagged an intraday high of $35.95 and has hovered near that mark most of the day. Another rejection here could send the shares back for a test of former support in the 27-27.50 area.

Mylan Laboratories: Stepping away from Internet-related stocks for a moment, we find Mylan Laboratories (NYSE:MYL) clinging to support in the 20 region. The company announced plans this morning to acquire a 71.5-percent stake in Indian drug maker Matrix Laboratories for $736 million. The stock has pulled back on the news, but is clinging to the 20 level, which served as support in the past for the shares. Furthermore, the 20 strike is the site of peak put open interest in both the September and October series of MYL, with a total of more than 10,500 contracts.
