This would qualify for investors as a "good day" (emphasis mine):

Google Inc. continues to confound the skeptics who thought the online search engine leader would sputter after striking it rich in a closely watched IPO last summer. The Mountain View-based company reported Tuesday that its fourth-quarter profit improved sevenfold from the previous year, much to Wall Street's delight. Investors appeared ready to push Google's stock to a new high when trading begins Wednesday on the Nasdaq Stock Market.

Google's likely to look at Microsoft's unveiled search engine less as a challenge than motivation to do better. I'm considering a slight investment.
