Apple, Amazon and Brocade Communications this week gave IT investors cheer as the tech sector, despite inflation fears, looks upbeat at the midpoint of the third quarter.

Apple gained US$6.20 to close at $175.75 Monday, continuing to trade up during the next several days following comments by CEO Steve Jobs in the Wall Street Journal. Jobs said that more than 60 million applications for the iPhone have been downloaded and that the company has taken in $30 million in revenue in the one month since the iPhone 3G was launched. At the current rate of about $1 million a day, Apple stands to rake in $360 million from the iPhone in one year.

Market watchers were quick to flag the fact that, after Apple's close of $179.32 on Wednesday, the company's market capitalization (the share price multiplied by number of outstanding shares) exceeded that of high-flying Google. Google's market cap was $157.23 billion, while Apple's was $158.84. Though Google shares were $500.03, it has fewer outstanding shares.

On Thursday, Apple slipped by several cents to close at $179.23, but market analysts are likely to remain upbeat about the company for some time to come. For example, Goldman Sachs on Thursday raised its price target on retailer Best Buy from $42 to $45 just because the mass-market consumer chain announced it was going to start carrying the iPhone.

Amazon's Kindle, meanwhile, is doing wonders for confidence in the online retailer. Company shares rose $7.58 Monday to close at $88.09 on predictions that the electronic book reader will be a winner for consumers. Citigroup analyst Mark Mahaney said in a research note that he believes Kindle sales will be twice as high as his original predictions. Mahaney now forecasts that 380,000 of the devices will be sold this year. Amazon shares stayed high throughout the week, closing Thursday at $88.03.

Brocade results for its third fiscal quarter helped restore some faith in the U.S. tech market. User interest in networked storage fueled double-digit sales growth and earnings that exceeded expectations. The company said Wednesday that quarterly revenue was $365.7 million, up about 12 percent from a year earlier. Net income was almost double that of a year earlier, hitting $20.3 million. The strong results came in even as the company depended more than ever on U.S. sales. Sixty-five percent of revenue came from the U.S. for the quarter, compared to 58 percent last year.
