A weekly tour of tech
The week's top stock, Intuit, creator of Quicken and new owner of Fool-favorite, reported $0.38 in second-quarter earnings per share, beating the consensus estimate by $0.06.

CEO Brad Smith credited market share gains for its TurboTax software. During a conference call with analysts, he said that his company was winning against rival H&R Block -- enough so that Inuit now estimates TurboTax revenue will improve 8% to 12% this year, up from earlier estimates of 4% to 8%, Reuters reports.

NVIDIA suffered despite posting good fiscal fourth quarter results. Revenue more than doubled to $983 million, resulting in a $0.23 per share profit. And those numbers should continue improving: NVIDIA chief executive Jen-Hsun Huang reiterated that its contract manufacturers have yet to keep up with demand from customers.

Finally, Dell reported lower fourth-quarter profit and a dangerously thin 0.2% margin for its consumer products division. Total revenue, meanwhile, rose 11%, to $14.9 billion. A week of net selling by Dell investors suggests they see this as a value-destroying combination; I think they're right.
