The Federal Reserve's next Beige Book report is scheduled to be released this week. This report is a compilation of anecdotal information on current economic conditions from each of the 12 Federal Reserve Bank districts, and it is released eight times a year. The data comes from interviews with business contacts, economists, market experts, and other sources. The June report is expected to show strengthening signs of expansion, though results could be mixed across the 12 districts.

Economic data due out this week include:

The Federal Reserve is scheduled to release its next Beige Book report of economic conditions on Wednesday, offering perhaps the best glimpse yet whether the recession has bottomed in the United States. The Beige Book report in March suggested that, by most measures, the economy was continuing to deteriorate and that prospects for near-term improvement was poor. But the April report showed that the deterioration was beginning to slow in some regions. Also, the TIPP Economic Optimism Index is scheduled to be released Tuesday, and the University of Michigan Consumer Sentiment Index comes out Friday. So by the end of the week, we could have a good gauge of the mood over the U.S. economy.

It was a quiet week, but here are highlights from this past week's earnings coverage from BloggingStocks:

• Amgen Inc. (NASDAQ: AMGN) earnings growth prospects for 2009 make the stock worth a look.
• Big Lots Inc. (NYSE: BIG) offered no 2009 guidance but may benefit from bankruptcies of other retailers.
• Cal-Maine Foods Inc. (NASDAQ: CALM) Q2 earnings fell more than expected but revenue rose.
• Chevron Corp. (NYSE: CVX) said it will soon post preliminary Q4 results in the face of falling oil prices.
• Piedmont Natural Gas Co. Inc. (NYSE: PNY) reported a widened Q4 loss while revenue improved.
• Take-Two Interactive Software Inc. (NASDAQ: TTWO) earnings prospects may make the stock a bargain.

Also, a survey indicated that U.S. corporate profits in the fourth quarter probably fell for the sixth straight quarter. Interest cuts haven't helped bank earnings, will the Fed buying mortgage-backed securities do better? And, are food stocks still a defensive play?

Upcoming earnings releases include Bed Bath & Beyond (NASDAQ: BBBY), Constellation Brands (NYSE: STZ), Family Dollar (NYSE: FDO), and Monsanto (NYSE: MON).

Piedmont Natural Gas Company, Inc. (NYSE: PNY) is one of the few corporations to report earnings this week -- and, judging by its results, that may be a good thing. PNY reported a widened fourth-quarter loss of $13.2 million, or 18 cents per share, while revenue improved by 12% to $311.8 million. Gross margin for the period contracted from 29.1% to 28.1%.

Ahead of the report, analysts were expecting a more modest quarterly loss of about 13 cents per share, according to Thomson Financial. Piedmont's forecast for the next fiscal year also fell short of Wall Street's expectations; the company backed its fiscal 2009 guidance for earnings of $1.55 to $1.65 per share, compared to analysts' consensus estimate for earnings of $1.66 per share.

In last week's preview we took a peek at expectations for Campbell Soup earnings, but now the company is scheduled to report fiscal fourth quarter results this coming Thursday. With Krispy Kreme also among the handful of companies scheduled to report this week, we may yet see whether consumers are turning to comfort foods in these uncertain times.

Campbell Soup Co. (NYSE: CPB), the world's biggest soup maker, is still expected by analysts surveyed by Thomson Financial to post net income of 25 cents per share (up 44.0% from a year ago) on revenue of $1.7 billion (up 7.4%). The Camden, N.J.-based company has just missed earnings estimates in the past few quarters. Its long-term EPS growth forecast is 7.9%, which is less than the industry average, but about the same as rivals Kraft Foods (NYSE: KFT) and HJ Heinz (NYSE: HNZ). The analysts' consensus recommendation is currently to buy Campbell.

Hip, Canadian apparel retailer Lululemon Athletica Inc. (NASDAQ: LULU) is also anticipated to be a big earnings gainer when it reports this week. Net income is expected to come in at 13 cents per share (up 46.2% from a year ago) on revenue of $88.2 million (up 50.3%). Lululemon met expectations when it reported 12 cents per share in the previous quarter. Its long-term EPS growth forecast is a healthy 40.2%, which is better than the industry average and that of rival Under Armour Inc. (NYSE: UA). The analysts' consensus recommendation is currently to buy Lululemon.
