In North America, the big focus for independent exploration and production firms is on natural gas. Yet, there is still a good amount of oil to be tapped (assuming prices remain relatively high).

So this week, Denbury Resources (NYSE: DNR) capitalized on the opportunity by shelling out $3.2 billion for Encore Acquisition (NYSE: EAC). It's not cheap, coming at a 35% premium. Yet, the deal will create a powerhouse in oil exploration and production in North America.

interestingly enough, in a sign that credit markets are loosening up, JPMorgan (NYSE: JPM) has agreed to provide a revolver of $1.25 billion to bridge the deal.

The rally in the stock market and the return to profitability for some of the top banks has been hailed as a sign of a turnaround -- and proof that the interventionist financial policies of the past year worked.

But not so fast. In reality, a huge chunk of the profits banks are earnings can be directly attributed to their ability to borrow money at artificially low interest rates.

According to a report from the Center for Economic and Policy Research found that below market interest rates offered by The Federal Reserve accounted for 41% of JPMorgan's profits. At Bank of America, the number was 47%.

Last week, Goldman Sachs Group Inc. (NYSE: GS) and JPMorgan Chase & Co. (NYSE: JPM) reported stellar quarterly results. Lots more third quarter reports from the big banks are due this week.

However, analysts surveyed by Thomson Reuters anticipate year-over-year earnings declines from Bank of New York Mellon (NYSE: BK), BB&T Corp. (NYSE: BBT), M&T Bank Corp. (NYSE: MTB), Northern Trust Corp. (NASDAQ: NTRS), PNC Financial Services Group Inc. (NYSE: PNC), State Street Corp. (NYSE: STT), US Bancorp (NYSE: USB), and Wells Fargo & Co. (NYSE: WFC).

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

• Abbott Laboratories (NYSE: ABT) higher Q3 earnings topped expectations but revenue was in line.
• Advanced Micro Devices Inc. (NYSE: AMD) posted better-than-expected Q3 results, but shares sold off.
• Allegheny Technologies Inc. (NYSE: ATI) was downgraded on concerns about its Q4 guidance.
• Bank of America Corp. (NYSE: BAC) shares fell after it posted a deeper-than-expected quarterly loss.
• Citigroup Inc. (NYSE: C) fell victim to profit taking despite reporting better-than-expected earnings.
• CSX Corp. (NYSE: CSX) better-than-expected Q3 earnings sent shares higher, despite a decline in revenue.

I don't think anyone could have had a positive reaction to Bank of America's (NYSE: BAC) third-quarter report, which was released on Friday. According to Bloomberg, management lost $1 billion in the past three months. Big ouch on that one. The financial institution bled 26 cents per diluted share. No earnings beat here, either. Wall Street sent shares down 4.6% by the end of yesterday's trading session.

The year-ago period was a happier time. Back then, Bank of America was rolling in the dough, posting a profit of 15 cents per share. What a difference 12 months makes. Looking at the nine-month record perhaps gives a small amount of comfort to shareholders. The company made 39 cents per diluted share. Of course, that doesn't sit too well next to the $1.09 per diluted share booked in the comparable period. But at least it's not a loss, know what I mean?

Tuesday morning greeted us with earnings from banking behemoth JPMorgan Chase (NYSE: JPM). The company said it earned $3.59 billion and that it nearly doubled the amount of money it saved for loan losses in the third quarter.

Breaking the results down into per-share earnings, JPM trounced the consensus estimate. The bank earned 82 cents per share, nearly double the expected 49 cents per share. Quarterly revenue increased to $26.62 billion from last year's same-quarter revenue of $14.74 billion.

Goldman Sachs upgraded the banking sector last week, and this coming week we'll get a chance to see whether Goldman and other big banks reporting third quarter results will live up to the expectations of analysts surveyed by Thomson Reuters.

New York-based Goldman Sachs Group Inc. (NYSE: GS) looks set to be this week's earnings game winner. Analysts expect this dividend-paying company to report a third-quarter profit of $4.24 per share, which is 57.3% higher than in the same period of last year. Revenue for the period that ended in September is expected to be $11.0 billion. So far, the full-year forecast is for $17.74 per share on $44.6 billion.

Who does our Treasury Secretary speak to most of the time? Yup. You guessed it. It's the big three bankers.

Who are they? First, we have Lloyd Blankenstein, CEO of Goldman Sachs Group (NYSE GS). Then we have Jamie Dimon, CEO of JPMorgan Chase & Company (NYSE JPM) and then CEO, Vikam Pandt of Citigroup Inc. (NYSE C).

You are probably also wondering how do we know this? The Associated Press did a review of Geithner's calendar under the Freedom of Information Act.

In his first seven months on the job, Geithner made at least 80 contacts with the "big three." Not only that Geithner jumps to the phone when they call. They are the dominant players on Wall Street who can move markets and even economies.

TheStreet.com's Jim Cramer is not convinced that what was bad a week ago has suddenly turned good.

Feels almost too good to be true. Once again, did we dodge the more than 3% to 5% decline? Once again have we put the trouble behind us? Did we have just enough October scare to inoculate?

I remember a week ago thinking there weren't enough "October's the roughest month" articles perhaps because those who wrote the "sell in May" and "sell in September" pieces felt chastised. I thought that the word had come from editors on high-stop being so bearish already.

But then by Thursday we were all well aware of the power of Rocktober and next thing you know people were whispering crash by Friday.

Last week, we saw Shanda Games Ltd. (NASDAQ: GAME) raise a cool $1 billion in its IPO.

And today, there was another big-time offering: Talecris Biotherapeutics Holdings picked up $950 in its IPO (issuing 50 million shares at $19 each). This is the second largest IPO of 2009.

Talecris is one of the largest producers/marketers of plasma-derived protein therapies, dealing with things like chronic inflammatory demyelinating polyneuropathy (CIDP), primary immune deficiencies (PI), alpha-1 antitrypsin deficiency, bleeding disorders, and severe trauma.

One consequence of the credit crisis shutting off the debt financing LBOs used to make acquisitions is that private-equity executives increasingly find themselves feuding over power, money, and strategy. Bloomberg provides details of the ouster of Dominique Megret, former CEO of PAI Partners, France's biggest private-equity firm.

Lionel Zinsou and others partners delivered an ultimatum to Megret: they wanted more say in running the firm or they would resign from the investment committee.

Newegg, which is an electronics e-commerce site, got its start back in 2001, when the dot-com industry turned into a dot-bomb disaster. But the timing was brilliant as the company built a thriving business.

In fact, Newegg thinks the timing is also right for an IPO, which the company filed for this week.

The market seems to want to go up each day as it has relentlessly almost every trading session since April. But yesterday, it had a tiny setback after the FOMC announcement. Today the culprit was housing. The National Association of Realtors said existing home sales declined 2.7% in August. Every economist worth his salt said the number would rise.

Good news on the unemployment front did give the market an early boost this morning. Within an hour, though, bad news on the housing sales front wiped out the gains and moved the major indices into negative territory, where they have remained.

Here were today's unofficial closing numbers:

Dow 9,706.99 -41.56 (-0.43%)
S&P 500 1,050.78 -10.09 (-0.95%)
Nasdaq 2,107.61 -23.81 (-1.12%)
