"Marvell Technology (MRVL) delivered disappointing results for its fiscal Q4 2011 (ended January 2011), as well as even more disappointing guidance for its fiscal first quarter," notes tech sector expert Paul McWilliams.

The editor of Next Inning newsletter continues, And to make matters worse, it had one of the poorest conference call presentations that I've ever heard from a major semiconductor company. Nevertheless, we are adding to our position. Here's why.

Over the years, Marvell Technology (MRVL) has built a solid business in developing chips for PC storage. The problem is that, with the emergence of tablets, the market is feeling some pressure. While Marvell has been moving hard into the mobile space, the results have been muted.

So, it should be no surprise that the company's recent earnings report was fairly lackluster. In fact, the shares were off 8% to $16.75 in morning trading.

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Aeropostale Inc. (ARO) strong Q3 results topped analysts expectations, and it offered Q4 earnings guidance.
• Cascade Corp. (CASC) reported a surprise Q3 profit but lower revenue fell short of expectations.
• Collective Brands Inc. (PSS) reported strong Q3 earnings as well as same-store sales growth.
• Cost Plus Inc. (CPWM) narrowed its net loss in Q3 but revenue and same-stores sales declined.
• Del Monte Foods Co. (DLM) posted strong Q2 results and raised its earnings outlook for the full year.
• Diamond Foods Inc. (DMND) posted better-than-expected Q1 earnings, but said that revenue declined.

Cost Plus Inc. (CPWM) reported Thursday that its net loss from continuing operations for the third quarter of fiscal 2009 came to $22.3 million, or $1.01 per share, compared to a net loss of $24.0 million, or $1.09 per share, last year. Analysts surveyed by Thomson Reuters had expected a loss of $1.10 per share. Cost Plus also said net sales for the quarter totaled $181.9 million, a 10.4% decrease from the year-ago period. Same store sales for the quarter decreased 9.1% due in part to lower furniture sales and a relatively flat customer count.

Diamond Foods Inc. (DMND) reported a record profit of $0.88 per share for the first quarter of fiscal 2010. That was 38% higher than a year ago and topped the analysts' consensus forecast of $0.81 per share. Net sales for the quarter came to $180.6 million, 8% lower than in the prior year, due in part to a late walnut crop harvest. Diamond's forecast for the fiscal year are EPS of $1.72 to $1.82 and revenue of $585 million to $605 million, which is in line with analysts' expectations.

Marvell Technology Group (MRVL) is scheduled to take the earnings stage after the closing bell. Ahead of the tech company's fiscal third-quarter report, analysts are anticipating a profit of 27 cents per share, up from its year-ago net income of 23 cents per share. Sales for the quarter are expected to total $770 million.

If history is any guide, Marvell could very well exceed these consensus estimates. During the past four reporting periods, the company has consistently met or surpassed analysts' earnings expectations.
