There have been rumors that Germany is coming to aid of Greece, but there are some formidable obstacles in such a ploy.

First EU law bars the European Central Bank or national central banks from bailing out EU members through buying their debt or offering loans, according to a German parliament research unit."There are no identifiable grounds for an alternative interpretation."

Sugar is one of the most basic commodities. Countries throughout the world are wanting sugar. Supplies of sugar are reaching a 20 year low this year. The shortage may become especially acute in the third quarter.

Here some supply/demand statistics:

• India the biggest importer may need an extra 2.5 to 3 million tons to meet a 7 million ton deficit.
• China, the biggest consumer after India may have a deficit of 3.3 million tons.

During a crisis, never mind what the media or government officials are saying, follow the money.

The Mercantile Exchange (CME) posts open contracts for each currency traded -- both long and short positions. By subtracting them you can get a sense of whether traders are net long or short. In the case of the euro, traders are net short 40,000 contracts or nearly $8 billion.

Meanwhile, officials of struggling countries, Greece, Spain and Portugal are telling the media that they have things under control. Elena Salgado, Spanish finance minister and Jose Manuel Campo, her deputy flew to London to meet with bondholders, the Financial Times reports. They want to reassure promises to cut Spain's budget deficit by 3% of GDP by 2013. But then the treasury wants to raise 116.7 billion euros.

It sometimes is a small, unpredicted event that moves markets. Today it was Jean-Claude Trichet, the president of the European Central Bank. He unexpectedly left a meeting in Australia to attend special meeting of European leaders to address the region's economy.

That was the trigger that shot off a turnaround in world markets. Stocks and commodities are trading higher in anticipation that the Greek sovereign debt problem will be dealt with. The U.S. market, just opened, did it with a bang as the Dow industrials more than recovered its triple digit loss from Monday to be back above the 10,000 mark.

U.S. stock futures advanced Tuesday, a day after the Dow Jones Industrial Average finished below the 10,000 mark for the first time since early November. With investors encouraged by signs the EU could bail out Greece, bargain hunters searched for deals following the selloff.

U.S. stocks dropped Monday for the third time in four sessions, with the S&P 500 falling 0.9% and the Dow industrials falling over 100 points, or 1%. Concerns about European debt weighed on Wall Street as was the outlook for the U.S. economy, especially in light of reports that Federal Reserve Chairman Ben Bernanke will begin laying the groundwork for credit tightening later in the year.

The Dow Jones Industrial Average sank below 10,000 Monday, closing at 9,908.39. So what? In market analysis, round numbers like 10,000 often trigger a change in market sentiment.

For example, when the Dow first pushed through 10,000 on the upside in 1999, investors and traders took this as a sign of strength. Conversely, when it crashed through 10,000 on its way down to 6,400, panic gripped Wall Street. Then, in 2009, we had a bounce back through 10,000 on the upside in November. Again, investors and traders saw this as a sign of strength.

Looking back just a few weeks, the markets ushered in the new year with euphoria. Within a few short weeks, things have turned sour. The Dow dropped below the 10,000 mark last week. S&P 500 is down 7.3% from its 15-month closing peak.

Now the question facing investors and traders is whether the market is in a corrective phase. Eric Kuby of NorthStar Investment Management Group thinks so. "I'm in the camp that believes that we are in a correction," he said.

Investors and traders are in a quandary, trying to figure out if the economy is, indeed, improving.

One measure of growth is consumer spending. Consumer spending accounts for 70% of GDP, and it is the engine that has kept the economy growing over the past decade.

Well, consumer credit has fallen for eleven straight months. The recession has taken a harsh toll on the consumer. We have about 17 million people out of work. These persons certainly are spending only for basic necessities.

Germany's industrial production has led the rebound in Europe. That was until the last quarter of 2009. In December, Germany's industrial production dropped 2.6% after rising 0.7% in November.

Germany supposedly turned the corner in the second quarter of 2009. But Alexander Koch, economist for Unicredit in Munich said: "The most vibrant part of the rebound" in industry was apparently over. One reason is that Germany ended subsidies to its auto industry recently.

Several factors converging on the metals markets are causing a sell off.

First, China has taken steps to curb bank lending. Much of the Chinese stimulus money has gone into the purchase of raw materials. Now, with things cooling down, traders are less willing to stockpile base metals.

Second, U.S. payrolls fell by 20,000 last month, indicating sluggishness in the U.S. economy.

On Thursday, markets across Europe, Asia and the U.S. sold off sharply. The reason is concern over Greece, Spain and Portugal being unable to manage their sovereign debts. The problem did not vanish overnight. The spread between the Greek and German 10-year government debt expanded since Thursday. Investors and traders sold the euro and bought dollars. Again on Friday, even with the Swiss Central Bank selling its own currency, the euro is still under pressure.

The dollar is strong again Friday, with the U.S. dollar index trading at 80.39, up .315 (8:30 EDT). In contrast, the euro has fallen 1.1% so far this week. This is the fourth consecutive week of losses.

U.S. stock futures were lower this morning, as investors anxiously awaited January's jobs report. Following Wall Street's worst day in more than nine months, and as overseas markets skidded on global economic recovery fear and debt issues at some European countries, investors fretted ahead of key U.S. employment data.

[Update: Stock futures recovered after the jobs data and now point to a higher start on Wall Street. The jobs data showed an unexpected decline in the unemployment rate to 9.7%, but payroll fell by 20,000.]

At 8:30 a.m., the Labor Department will report January figures on nonfarm payroll. Job losses during the Great Recession have been huge and they're about to get bigger. Economists expect the report to show 5,000-15,000 jobs created during the month. The unemployment rate is expected to remain at 10%.

This morning the big news of the day was the drubbing of European stock markets as fear spread throughout the region. Fear was generated by concern that some European countries could default on their sovereign debt. Among them are Greece, Spain, and Portugal.

Greece's budget gap is 12.7% of GDP Greece has to slash spending and may need IMF assistance.

Investors sold investment deemed risky such as commodities, gold and stocks and moved their money into bonds. This started a selling frenzy in commodities with oil falling $3.14 per barrel to $73.14 per barrel. Brent crude fell $3.79 per barrel to $72.13 per barrel.

Insurance giant Aetna Inc. (AET) will be reporting its fourth quarter numbers tomorrow before the market opens.

Analysts are expecting to see the company show earnings of 42 cents per share. During the same period last year the company had earnings of 96 cents per share.

All swans were thought to be white until someone happened to come across a black one. All Toyota's were thought to be well made until someone discovered, oh, say, maybe two million cars that might not be -- part of a cautionary vehicle recall.

If you are a shareholder of Toyota Motor Corp. (TM) which past GM as the largest automobile manufacturer last year -- oddly, the same year it reported its first losses (along with everyone else) -- then you now have a first hand experience of the inherent problems or uselessness in trying to predict where trouble may arise.
