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

• Blockbuster Inc. (BBI) Q1 net loss was in line with estimates and same-store sales declined, shares also fell.
• CA Inc. (CA) shares sold off on high volume following the Q4 earnings miss and disappointing guidance.
• Cigna Corp. (CI) reported better-than-expected Q1 earnings and higher revenue, and reaffirmed its full-year outlook.
• Cisco Systems Inc. (CSCO) beat Q3 earnings and revenue expectations in the "strongest quarter in our history."
• Dean Foods Co. (DF) lower Q1earnings beat analysts' estimates, but shares fell on heavy volume afterward.
• Denny's Corp. (DENN) bested consensus estimates and year-ago EPS by a penny, but said same-store sales fell.

Dole Food Company, Inc. (DOLE) is, at the time of this writing, down 76 cents to $9.98. That's a loss in value of 7%. The company had posted its Q1 numbers after the bell on Monday. The market is obviously not infatuated with them today.

According to the press release, adjusted EBITDA dropped to $85 million from $122 million. Net cash from operating activities plunged to $19 million from $39 million. These are not attractive statistics. A bad market environment in Europe and Asia apparently hurt the performance of fresh fruit.
