Baidu.com, Inc. (BIDU) and Google Inc (GOOG) are both stocks to keep on your radar this week. In a post three weeks ago we saw that short sellers were at odds with analysts as shares of BIDU tested a critical level near 300. Meanwhile, a post two weeks ago noted that GOOG was one of the most liked stocks by analysts.

Shares of Baidu.com lost over 4% yesterday and closed below support for the first time since early-April. A look to the technical action of Google shows that stock is threatening to fill the gap up that happened in mid-April.

The potential breakdown of Google Inc (GOOG) comes as the company prepares to report earnings on Thursday. You may remember that the April surge in Google came after their last report showed better-than-expected numbers.

The chart below is interesting as it shows that shares of BIDU and GOOG have been more less tied at the hip this year.

This leaves us with a situation where both stocks are showing a year-to-date loss of more than 25% and both stocks are well liked on the Street. I think this puts pressure on Google to deliver and I think the table below is worth keeping in mind. It shows how Google's stock has reacted to the last 8 reports. The aspect that stood out is the consistent alternating reactions. In other words, there has been a tendency for an upbeat reaction to be followed by a downbeat one. I guess the question now is this - will this time be different?
