Humana (HUM), one of the nations' biggest providers of private run Medicare Advantage health plans, showed mixed results on Monday in their Q4 results. Revenues were higher, but net earnings fell, due mainly to the acquisition of Concentra Inc. Concentra provides services such as occupational medicine , urgent care and physical therapy.

The company reported a profit of $107.3 million or 63 cents a share, down from $250.7 million of $1.48 a share a year ago, as reported in the Wall Street Journal. The latest period included $1.02 a share in acquisition and related costs. Revenue increased 9.4% to $8.35 billion. Analysts had predicted earnings of 81 cents on revenue of $8.36 billion.

Things look to be pretty quiet on the economic calendar this week. Here are the highlights:

• Tuesday: Weekly chain-store sales
• Wednesday: Federal budget balance for January
• Thursday: Wholesale trade data in December
• Friday: Trade balance in December and the weekly inflation survey

However, three iconic companies -- Walt Disney (DIS), Coca-Cola (KO) and Hasbro (HAS) -- highlight this week's quarterly results. Here's a look at what analysts surveyed by Thomson Reuters are anticipating from these and others.

Today started out strong and ended up even stronger with triple-digit DJIA gains. The reports from ISM showed no manufacturing recession and actually showed more employment improvements. This was on the heels of a strong Chinese auto figure and on all major indexes outside of the US trading higher. The S&P 500 even got back above its 200-day moving average.

Here were today's unofficial closing bell readings:

Dow Jones 10,674.38 +208.44 (1.99%)
S&P 500 1,125.86 +24.26 (2.20%)
Nasdaq 2,295.36 +40.66 (1.80%)

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

• Coinstar Inc. (CSTR) shares surged following stronger-than-expected Q1 earnings driven by DVD rentals.
• Humana Inc. (HUM) shares traded lower despite the report of better-than-expected earnings for Q1.
• IMAX Corp. (IMAX) reported strong Q1 results that easily topped consensus estimates, but shares declined.
• Kellogg Co. (K) topped Q1 earnings expectations and announced a share buyback program.
• Office Depot Inc. (ODP) Q1 earnings fell short of consensus estimates and same-store sales declined.

Humana Inc. (HUM), whose colleagues include Aetna Inc. (AET) and CIGNA Corporation (CI), reported Q1 earnings earlier today. The health insurer isn't doing so well, unfortunately. In late trading, shares were down almost 3% to $43.73. Volume is above the norm, as you might expect.

I've covered many stocks that are near their 52-week highs, but this one doesn't fall into such a desirable category. Alas, the 52-week high on the shares stands at $52.66. And, as you can see from the following one-year chart, the stock began its pullback after it topped out in January. Since then, things haven't been too exciting.

Humana Inc. (HUM), who's shares (like other insurers') received a nice bump from the outcome of the special election in Massachusetts, is scheduled to discuss its fourth-quarter 2009 financial results and 2010 guidance in a conference call Monday, Feb. 1, at 9:00 AM (ET). A live webcast of the call will be available at the company's website.

During the three months that ended in December, Humana expanded its Medicare offerings and launched a share buyback program and a social media tool. Analysts surveyed by Thomson Reuters are looking for earnings for that period to have grown 27.7% year over year to $1.48 cents per share. Revenue for the quarter is expected to be 4.0% higher to $7.8 billion.

TheStreet.com's Jim Cramer says the Senate is filled with more-savvy politicians, and the upside for beaten-down names is huge.

Nancy Pelosi has now said her piece. The most unpopular Speaker of the House in the history of Wall Street has gotten her precious health care legislation through the House after ramming through a stimulus package that had far too little infrastructure and far too much pay raise for municipal and state workers, the most powerful interest group in the country.

But this time the Senate sees through it, and the politicians -- despite Pelosi's insistence that Tuesday's election went her way -- know better. There are pages after pages after pages in this bill that look threatening. But here's the rub: This bill's public option, the one that is supposed to be a killer to everything health care, should affect no more than 6 million people over a 10-year period, according to the Congressional Budget Office. In order to get 60 votes in the Senate, even that may prove to be too powerful an option.
