TheStreet.com's Jim Cramer says that from a chart perspective, this could be about the greatest bull market in history.

Chart to chart to chart this weekend and all I see, except for a couple of health maintenance, medical device and drug companies plus some fertilizer stocks, is just a remarkable and, yes, unheralded run in every single group.

Some of them are of the pure recovery style: every oil and gas, now including refinery, as the crude price inches back to $100 and natural gas has started its way back up; the life insurers that were left for dead when we decided that all commercial mortgages would be destroyed taking them with the bad loans; the overly-indebted companies like Textron (NYSE: TXT) (Cramer's Take) that have roared back without any real support from anyone.

But others are just monumental. Anything paper or wood or glass. These aren't quitting.

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

• Aetna Inc. (NYSE: AET) lowered its 2009 earnings guidance, initially sending the share price lower.
• Ciena Corp. (NASDAQ: CIEN) reported a bigger-than-expected Q2 net loss as revenues sank.
• Collective Brands Inc. (NYSE: PSS) saw Q1 earnings and sales decline, but beat Wall Street estimates.
• Google Inc. (NASDAQ: GOOG) earnings prospects led Goldman Sachs analysts to increase its forecasts.
• Guess? Inc. (NYSE: GES) weak Q1 results topped estimates and it offered guidance that pleased investors.

A recent Time magazine cover story described it as, "The New Frugality." The "it" here is the change in behavior, attitudes and even values Americans are embracing as a byproduct of the "Great Recession." It's just a fact that most of us have in some way or another altered our spending habits to a more frugal lifestyle as a direct result of the worst economic downturn since the 1930s.

One company feeling the sting of the country's new frugality is high-end retailer Williams-Sonoma (NYSE: WSM). Today the company reported a Q1 loss of $18.7 million, or 18 cents a share, compared with a profit of $10.4 million, or 10 cents a share, a year earlier. A performance not uncommon for retail stocks these days.

The losses were actually smaller than the company had projected, but those previous projections included a slashed advertising budget, a cut in capital spending and lowered merchandise inventories. More importantly, the company said that revenue in the quarter ended May 3 fell 22% to $611.6 million. Yikes!

Of course, Wall Street rewarded the anemic results with a near-10% drop in Wednesday's trade. So, what does the Williams-Sonoma miss tell us?

Much of the attention this week will no doubt be on how the impending General Motors (NYSE: GM) bankruptcy will shake out, as well as the usual economic concerns: Has the housing market bottomed? Will oil prices keep rising? Is the employment situation getting any better? And so on (see highlights of the economic calendar below).

What probably won't get much attention are quarterly earnings, as the earnings season for this quarter winds down. But there are a few reports that analysts surveyed by Thomson Reuters have high hopes for.

Analyst upgrades:

• FBR Capital upgraded KBW, Inc (NYSE: KBW) to Market Perform from Underperform as it sees increased capital-raising opportunities for small and mid-sized banks and believes the company's quarter is off to a strong start. The firm raised its target price to $23 from $18.
• Pali Capital upgraded Morgan Stanley (NYSE: MS) to Buy from Neutral on expectations the company's strategic shift towards advisory, distribution and retail will be monetized sooner than expected and its capital markets business is gaining traction. The firm set a $33 target on the stock.
• Baird upgraded Stericycle (NASDAQ: SRCL) to Outperform from Neutral and raised its target to $58 from $55 based on valuation predictable earnings, and its market leading platform.
• Apollo Investment (NYSE: AINV) was raised to Outperform from Market Perform at Keefe Bruyette.

• Philips Electronics (NYSE: PHG) was upgraded at ING Group to Buy from Hold.
  
• Hospira (NYSE: HSP) was upgraded to Outperform from Market Perform at Leerink.

Home-products retailer Williams-Sonoma (NYSE: WSM), which runs such retail brands as Pottery Barn and West Elm in addition to its namesake chain, issued Q4 numbers on Tuesday. Well, they weren't spectacular. Surprised? No, I'm sure you weren't. I mean, when you sell stuff for homes, you've got to expect that you're going to see some weakness. And there's plenty of it here.

Revenues decreased almost 27% during the quarter, and earnings per share on an adjusted basis dropped over 70% to 31 cents. That beat estimates of 16 cents per share, according to Reuters' analysts, but forgive me if I don't jump up and down over that performance. And what about same-store sales? They were mighty bad. On an overall basis, they went down by over 22%.

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

Job cuts:

• EMC (NYSE: EMC), the data-storage firm, announced 2,400 job cuts, or about 6% of its workforce. EMC also cut the salaries of top executives. Its preliminary results, though, were inline with estimates. EMC shares rose 4.2% in premarket trading.

The first trading session of the 2009 may have brought some optimism with it as markets rallied, but it's difficult to imagine all our troubles over after a year that set one bad and worse record after another. Stocks mirrored the global economic slowdown brought on by the housing market and the financial markets crises.

Still, there are many who still seek to invest in hope that one day they could get nice returns on their investments. While the recent volatility in the stock market benefited some shrewd day traders, most investors know to stick to a long-term, stable investment plan.

To help achieve some of these long-term return, BloggingStocks contributors continued to suggest some companies to invest in, as well as some to avoid:

Activision Blizzard (NASDAQ: ATVI) -- despite having his confidence in the stock shaken somewhat lately as sales may have been softer than expected, Steven Mallas is still bullish on the stock and feels it is attractive at these levels. Take-Two Interactive (NASDAQ: TTWO), however, "seems a little scary to be buying in now," he says.
