Each week, I report the results of the Big Idea Portfolio, a collection of five tech stocks that I believe will crush the market over a three-year period. I've done it before; my last tussle with Mr. Market ended with me beating the index's average return by 13.35%.

Real money was on the line then as it is now, which means any one of the five stocks you see below could cause me a lot of public embarrassment. This week, Rackspace Hosting (NYSE:RAX) cost me the most even if Apple (NASDAQ:AAPL) dominated the headlines.

Rackspace fell nearly eight percentage points in a week where Amazon.com (NASDAQ:AMZN) endured multiple problems in a suburban Virginia data center that also suffered downtime during a series of violent summer thunderstorms plaguing the D.C. area. Thursday night, the company reported its first loss since 2003 because of heavy investments in all lines of business. Further improvement in its Amazon Web Services cloud computing offerings could make it harder for Rackspace to win new clients.

Apple, meanwhile, reported huge gains in several areas but still came short of analyst estimates in reporting fiscal fourth-quarter earnings. Revenue grew 27.2% to $35.97 billion while profits improved 22.9% to $8.67 a share. Wall Street was hoping for $8.75 a share on $35.8 billion in revenue, according to data compiled by Yahoo! Finance.

The stock fell more than 3% in Friday morning's trading. Foolish colleague Evan Niu sees that as a buying opportunity for those who don't already own shares; I do as well. In fact, I'd buy more if Apple weren't already (by far) the largest position in our family portfolio.

Forget for a moment that the Mac maker is now selling two potential blockbuster products during the holiday quarter -- i.e., the iPhone 5 and the iPad Mini. Apple now boasts more than $120 billion in cash and investments on its books and is due to pay another $2.65 a share in dividends on Nov. 15.

What's the Big Idea this week?
Rackspace and Apple may have lost this time, but Mr. Market took an even bigger beating to fall a point back versus last week's tally. The small cap Russell 2000 dipped 0.51% while the Nasdaq fell 0.65% . Both the S&P 500, down 1.41% , and the Dow Jones Industrial Average, off 1.79% , fell more than twice as much, according to data supplied by The Wall Street Journal. Here's a closer look at where I stood through Thursday's close:

Notable newsmakers
Among the other stocks in the portfolio, Riverbed rallied even as peer F5 Networks (NASDAQ:FFIV) blamed troubling macroeconomic conditions for its fiscal fourth-quarter miss and poor guidance for the upcoming quarter. The stock plunged some 12% the day of the report.

Salesforce.com also fell for most of the week before rallying on Friday morning. We can thank NetSuite (NYSE:N) for the rally. The company, which specializes in back-end business software such as accounting and inventory delivered via the cloud, beat Wall Street estimates on both the top and bottom lines while continuing to produce huge gains in cash flow. Operating cash flow climbed 61% in the third quarter.

Finally, Microsoft (NASDAQ: MSFT) began selling its new Surface tablet at retail stores on Friday. Yet the early numbers say the device is already a hit. U.S. pre-orders have already sold out, while reports from the UK show surging demand there as well.
