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

• Bidz.com Inc. (NASDAQ: BIDZ) Q4 earnings release included notice about an SEC investigation.
• Dell Inc. (NASDAQ: DELL) saw net income drop by almost 50%, falling short of estimates.
• Ducommun Inc. (NYSE: DCO) received an analyst's downgrade after its Q4 earnings release.
• Gap Inc. (NYSE: GPS) said Q4 earnings fell due to weakness at Gap and Old Navy stores.

Public Storage (NYSE: PSA - option chain) shares are headed higher today after the company reported a fourth-quarter profit of $151.7 million after the close yesterday. PSA's funds from operations of $1.49 per share beat analysts' projections of $1.28 per share.

This industry has been one of my favorites for a while as it addresses Americans' dual compulsions to buy stuff and never get rid of it. Plus, their business model is pretty nice -- they charge a whole lot of cash just store your junk in a garage that cost them very little to build and maintain. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on PSA.

There are a number of ways to play the recession / depression on the market that might seem, at first, counter-intuitive but on second glance make sense. Here's one -- Public Storage (NYSE: PSA), a REIT focused on ownership of public storage facilities.

Like the rest of the real estate market, it's been hammered -- down just over 52% from 52-week highs of $110 per share. But public / self storage facilities should actually prosper in this market. Here's why: People still have a lot of stuff, but many of them are going to have less house very soon. Same goes for businesses that are putting off plans to expand offices or rent warehouses and need a place to park things.

I have watched this controversial advertisement for the Public Storage Co. over and over and I take no offense. Spike has portrayed it as the most anti-Semitic "worst ever" commercial, but I do not see it that way. Given my father is a survivor of the Holocaust (Warsaw Ghetto and all) and I have grown up with many accounts of murderous atrocities and learned of, and experienced, many more anti-Semitic accounts, I think Spike is way off base with this one.

Most mergers are driven by the notion, sometimes wildly mistaken, that the combination will bring both a competitive advantage. Some pairs of companies, however, seem so intuitively right for one another, no bottom-line considerations should be allowed to interfere with their matrimony. Like a slot machine and a blue hair with a pocket full of quarters, these two were meant for one another.

George Carlin has a famous rap (NSFW) about Americans and our love of stuff, which drives our need to build more places to put our stuff. That's always struck me as an integrated business plan. Two seemingly perfect partners for such a business are Dollar General (NYSE: DG) and Public Storage (NYSE: PSA).

Dollar General is a leader in recreational shopping for the denominationally challenged. If you have a hankering for neon-colored plastic, something covered in polyester fur, food with the half-life of uranium-235 or clothing with the style of Piltdown Man, DG is your go-to source.There you'll find shelf after shelf of non-essentials, the kind that end up in storage sheds. Currently, the 8,260-store company is in the process of merging with Buck Holdings LP.

If this deal falters, though, how about a merger with Public Storage? PSA (I'm a little uneasy with a company whose stock ticker is the name of a prostate cancer screening test, by the way) is a REIT with direct and indirect interest in over 2,000 self-storage developments in the U.S., containing, I'm sure, a great deal of material from Dollar General. The merger would be an excellent opportunity to double-down on America's seemingly inexhaustible need for more stuff.

MOST NOTEWORTHY: REITs, Business Objects, Allstate Corp and P&C Insurance were today's noteworthy downgrades:

• Deutsche Bank downgraded REITs AvalonBay (NYSE: AVB), Boston Properties (NYSE: BXP), Health Care REIT (NYSE: HCN), Kimco (NYSE: KIM) and Public Storage (NYSE: PSA) to Hold from Buy on valuation following the recent share appreciation.
  
• Business Objects (NASDAQ: BOBJ) was downgraded to Neutral from Outperform at Baird following its acquisition by SAP AG (NYSE: SAP).
  
• Wachovia downgraded Allstate Corporation (NYSE: ALL) to Market Perform from Outperform and P&C Insurance (NYSE: PGR) citing deteriorating fundamentals in personal lines.

OTHER DOWNGRADES:

• UBS downgraded BEA Systems (NASDAQ: BEAS) to Neutral from Buy.
  
• JP Morgan downgraded Merrill Lynch (NYSE: MER) to Neutral from Outperform.
  
• Sealy Corporation (NYSE: ZZ) was downgraded to Neutral from Buy at Banc of America.
  
• Friedman Billings downgraded technology stocks, lowering ASE Test Limited (NASDAQ: ASTSF), ASML Holding (NASDAQ: ASML), KLA-Tencor (NASDAQ: KLAC) and Rudolph Technologies (NASDAQ: RTEC) to Market Perform from Outperform.

The past six months have been brutal for Public Storage Inc. (NYSE: PSA), which has seen its stock price lose about 35%; it's now trading below where it was 12 months ago. The company's net income in 2006 was well below what it was in 2005, after a few years of steady growth, and the first two quarters of 2007 haven't been much better. Net income in the second quarter was down nearly 25% from the second quarter of 2006, and for the first six months it is down nearly 50% from the first half of 2006. No wonder investors have been worried.

But PSA argues its results are due in large part to the amortization and depreciation costs associated with its
acquisition of Shurgard, the third-largest self-storage company in the U.S., and the largest one in Europe. While this acquisition may have hurt PSA in the short term, I think it's going to help the company a great deal in the long run. PSA has always benefited from strong management, and I think it's going to make the increased revenues from Shurgard turn into increased profits before too long. PSA is the leading self-storage company in the country, with modest if steady growth in same-store revenues, and the new acquisition will only make it stronger.

It may take some time for this growth to come. With a slowing housing market and an uncertain economy, people may be moving less and acquiring fewer goods that need storage. It's possible a slowing economy could force homeowners to move to smaller houses and require storage space, but generally it works the other way. Goldman Sachs recently released a report that lowered its earnings estimates for the next few years, and lowered its 12-month price target to $78 from $86.

But the Goldman report also claimed that PSA has strong growth potential, and it expects further acquisitions and higher rents to drive this growth. I think this is the right way to see this company -- but it may take a year or two. You may want to wait, but you could also buy now and enjoy the modest dividend (2.7%) while you wait for the company to return to where it should be. Public storage will always be in demand, and this company will be there to service that demand.

Type of Stock: The largest self-storage company in America, facing an uncertain economy.

Price Target: PSA has regained some ground (about 15%) after dropping from $117 to $68, and it's currently trading in the low $70s. I think it's a solid buy for the long term below $80 -- but you'll need to be patient.
