Here are some highlights from last week's earnings coverage from BloggingStocks:

• Caterpillar Inc. (NYSE: CAT) shares rose after it reaffirmed the 2009 outlook and forecast further growth.

VeriSign (NASDAQ: VRSN - option chain) stock is falling today after the company reported earnings last night, posting a second-quarter profit of $34.87 million or 18 cents per share. Excluding items, VRSN earned 31 cents per share, missing analysts' estimates by a penny. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on VRSN.

This morning, VRSN opened at $20.00. So far today the stock has hit a low of $18.64 and a high of $20.06. As of 11:45, VRSN is trading at $19.04, down $1.52 (-7.4%). The chart for VRSN looks bullish and S&P gives VRSN a positive 5 STARS (out of 5) strong buy ranking.

Last week's Fed Beige Book report and GDP numbers suggested that the economy may be stabilizing, and this coming week will bring plenty of economic data to confirm or deny that suggestion. On the schedule are consumer credit, construction spending, factory orders, and pending home sales for June, the employment situation, the Import Price Index, and new motor vehicle sales for July, as well as the ISM Manufacturing and Non-manufacturing Indexes for July.

The week will also bring quarterly reports from home builders Beazer Homes USA Inc. (NYSE: BZH), D.R. Horton Inc. (NYSE: DHI), and Pulte Homes Inc. (NYSE: PHM). Yet again, analysts surveyed by Thomson Reuters expect all three to have narrowed their losses in the most recent quarter. However, they've all tended to post deeper-than-expected losses in recent quarters as well. Analysts also expect to see their revenue down 45% or more for the past quarter. They forecast long-term EPS growth of 7% or more, but none of these homebuilders has a First Call consensus buy recommendation, not surprisingly. Short interest is falling off for Beazer and D.R. Horton, and D.R. Horton and Pulte have been reporting positive cash flow from operations, but all three of them said they had more long-term debt than cash in hand last time around. Mortgage insurer PMI Group Inc. (NYSE: PMI) is likewise expected to report that it narrowed its second-quarter loss.

TheStreet.com's Jim Cramer says companies saddled with high debt loads can be found in every sector in every business.

Overleveraged. Too much debt. Need to pay down debt. How many times have you read that story?

You read it so much because it plays out every day and plays havoc with stock picking almost every time you see a savory stock down on its luck.

This weekend, as I went through the charts, I was amazed at how low some stocks have gone, stocks that I would normally say to just take a flyer on, but turn out to have so much debt, short- and long-term, that they are just too dangerous.

Consider these perhaps poisonous morsels:

Hopefully we are either getting toward the beginning of the end in this bear trend. If not, we are in for a long 2008 between presidential candidates bantering caught in a weak economy and a down trending market. The daily sell-off is hard to argue against since buying only works for a short period right now. About the best thing the bulls could hang a shingle on today was an initial flat reading seen in some index after the open. That wasn't to hold. All of the same reasons that the bulls hung on to were overrun by the same arguments the bears have been using all along.

QLogic Corp. (NASDAQ: QLGC) was a winner after it actually raised guidance. Shares were up over 9% today in the final minutes at $15.27.

VeriSign Inc. (NASDAQ: VRSN) was a standout winner today. Shares were raised, although there are more questions than answers outstanding on this stock now. Shares were up 2.8% at $33.77 in today's final minutes.

Yahoo! Inc. (NASDAQ: YHOO) shares were down over 2% at $24.09 despite rumors on Jerry Yang about to resign. I called the company, and it denied such rumors right on the spot.

MOST NOTEWORTHY: Steel Dynamics, Nucor, Nokia and Wachovia were today's noteworthy upgrades:

• UBS upgraded Steel Dynamics (NASDAQ: STLD) and Nucor (NYSE: NUE) to Buy from Neutral and added them to their Short-Term Buy list citing oversold valuations and the belief that both will beat Q2 Street estimates and guide higher.
• Dresdner Kleinwort upgraded shares of Nokia (NYSE: NOK) to Buy from Add as they believe the company's second half of the year looks strong due to new product launches.
  
• Merrill Lynch upgraded Wachovia (NYSE: WB) to Neutral from Underperform on valuation as they believe credit headwinds are priced into the stock at current levels. Merrill also thinks WB would make a "good fit" for JP Morgan (JPM) and puts a realistic acquisition value on the company of $16-$20 per share.

OTHER UPGRADES:

• Verisign (NASDAQ: VRSN) was upgraded at Baird to Outperform from Neutral.
  
• Lehman upgraded Penn Virginia (NYSE: PVG) to Overweight from Equal Weight.
  
• Piper raised SGX Pharmaceuticals (NASDAQ: SGXP) to Neutral from Sell.

UBS has upgraded Hovnanian (NYSE:HOV) to "neutral" from "sell," according to Briefing.com. The news service also reports that Oppenheimer raised its price target for Verisign (NASDAQ:VRSN) to $42.

Lehman Brothers affirmed it "overweight" rating on Bank of New York (NYSE:BK) ahead of the company's annual meeting with brokers, according to the AP.

BMC Software (NYSE:BMC) started as "neutral" at UBS, according to Briefing.com.

Bessemer Venture Partners, which is the oldest VC firm in the US, has picked many winners such as Skype, VeriSign (NASDAQ: VRSN) and LinkedIn. So, what does the firm like right now? Well, one sector is on-demand business applications.

In fact, this week the firm led a $15 million investment in Intacct, which operates a web-based ERP system. In all, the firm has raised $29 million in the past nine months.

"We focus on small and mid size companies," said Marc Linden, Intacct's CFO, in an interview with me. "It's for those businesses that are graduating from Intuit's (NASDAQ: INTU) QuickBooks. And we estimate the market size at $7 billion."

No doubt, there are some tough competitors, such as NetSuite (NYSE: N). But with such a large market size, there should be room for a variety of players.

And what about the slowing economy? According to Linden, there is "no effect yet." Then again, by using an on-demand model, customers may be looking to Intacct to cut costs.

VeriSign (NASDAQ: VRSN) had excellent performance in 2007. The stock ran from the low $20s to the low $40s, and now has settled in at $37.54. My 2008 price target for VeriSign is $55. It will be an interesting year for this company -- the toll booth of the internet.

I wrote about VeriSign back in late May 2007 when the tenured CEO, Stratton Sclavos, abruptly left the company. Sclavos was CEO for 11 years, having taken the company through its 1998 IPO and many, many acquisitions. Since his quick departure last May, the stock has gone up from $25 to its current price. The market has voted favorably on this CEO's departure. So what makes VeriSign a great buy for 2008?

Regular readers of BloggingStocks will find no shortage of stock picks for 2008 on our pages. Steven Halpern alone has compiled about 120 picks from the investment advisors he follows. But plenty of other bloggers have favorites for 2008 to share.

In an effort to consolidate the wealth of ideas into one handy post, here are a few of our bloggers' favorite selections for the year ahead:

VeriSign (NASDAQ: VRSN) is the 2008 pick of Georges Yared (check out how his 2007 picks did). He expects this internet security and domain registry firm to sell off its non-core assets and grow its core business in 2008.

Priceline (NASDAQ: PCLN) is the current favorite of Beth Gaston Moon. It's already had an amazing run in 2007, climbing from about $45 to $120 a share. Looking for a lower-priced stock? Beth recently spotlighted 10 Stocks for Under $10.

Deckers Outdoor (NASDAQ: DECK) is a stock I picked in a recent video, which Beth likes as well. I think it will continue to surprise to the upside on the strength of sales of its trendy Ugg boots. Zac Bissonnette thinks it will no doubt flame out at some point.

MOST NOTEWORTHY: Sierra Wireless, Navteq, Goldleaf Financial, Infineon and VeriSign were today's noteworthy downgrades:

• Piper downgraded shares of Sierra Wireless (NASDAQ: SWIR) to Market Perform from Outperform to reflect increasing competition for the company's core businesses and longer term margin concerns.
