Stocks are expected to open modestly higher on Wall Street after a losing week last week. On Friday, stocks fell for the third straight day after reports on new-home sales and durable goods proved weaker than expected, leading investors to believe the economy has not yet emerged from the recession.

Stocks to watch today include pharmaceutical giant Johnson & Johnson (NYSE: JNJ), which agreed Monday to buy an 18% stake in European drug maker Crucell (NASDAQ: CRXL) for 301.8 million euros ($440 million), as part of a deal to develop flu vaccines.

The G-20 is meeting again, this time in Pittsburgh, and as is so often the case when the world's industrial powers gather, the operative phrase is 'lower your expectations.'

What can investors look for? Well, one thing investors should not look for is any G-20 type of action on banker compensation/bonuses, other than a call for each nation, 'to do more to ensure that constructive incentives are in place' to prevent a repeat of the lending practices/perverse incentives that helped trigger the global financial crisis. There is support for compensation caps in Europe (except Germany); however, the United States and United Kingdom oppose them, so the issue is a non-starter.

Yes, it is a holiday, but there are some markets open -- and they aren't doing all that well. With financial markets in London, Japan, and the United States shuttered for holidays, trading volume is thin -- and stocks are lower.

In Germany, the country's Ifo business-climate index fell short of expectations for May. The index did show a rise in activity during the month, but it only rose to 84.2 when 85 was expected. The survey is being called a "clear disappointment." One bit of data that wasn't disappointing was the ZEW indicator of German economic sentiment, which increased to 31.1 in May from April's reading of 13.0. This reading seems to indicate that many investors think the worst of the global crisis is over.

Following the Dow and the NASDAQ here in the Americas, European and Asian markets almost unilaterally lost any previous gains, as the major indexes all fell. Both Henry Paulson and Ben Bernanke were both being pitched in the media as potentially saying the credit market losses were hurting the U.S. economy. As a result, the U.S. dollar was at a record low against the euro.

If it's not one thing with the U.S. economy, it's another, when it comes to the complete mess the mortgage overextension problem has created. Said Roberto Mialish from Unicredit Markets & Investment Banking: "The markets are reacting negatively to the renewed credit crisis in the U.S. and that's hurting the dollar across the board ... the market is speculating that Bernanke will offer a gloomy outlook for the U.S. economy.''

Interesting article this week in the MIT Technology Review (OK, so I don't understand most of it, but I still aspire to be a geek) in the wake of the trading losses announced by Société Générale at the hands of rogue trader Jérôme Kerviel.

Last week, the French bank disclosed the $7.2 billion loss. In the wake of the disclosure, Bank of France chairman Christian Noyer declared to a French senate finance committee, "None of the controls within Societe Generale seem to have worked as they should have."

Interviewed in the article, MIT's Andrew Lo, head of the university's Laboratory of Financial Engineering, said that given the fact that all software systems have a human interface, "I would argue that it is impossible to prevent these disasters with 100 percent certainty."

To say the least, this has been one interesting and turbulent week for the stock market. We saw international markets crash for two days, severe down action, a three-quarter point emergency interest rate cut by the Fed, a $7 billion mistake in France and work on a rebate package in Congress.

It can be a little hard to understand international markets and how they all work. But allow me to use an analogy to explain their interaction.

We all grew up in a family, and one of the most important people in the family is Mom. Mom does a lot of work -- making meals, doing laundry, cleaning the house and even working outside of the house. Families can have very complicated interpersonal dynamics in them. There is a saying that "if Mama ain't happy ... nobody's happy." And I think there is some major truth to it.

But it applies to international markets as well. The U.S. market is the "mama" and the most important player. The $13 trillion U.S. economy is bigger, stronger and more dynamic than each of the other markets, and if it has troubles, other markets have troubles as well.

While the euro has risen by as much as 40% against the dollar since 2002, emerging market currencies have only seen gains of 17%.

Should investors sniff an opportunity?

Well, yes and no.

An article out this morning by the Financial Times examines this disparity.

The FT says, "Fear is part of the answer. Investors haven't forgotten the emerging market currency devaluations of the 1990s and early 2000s. For them it's 'no thanks, too risky.'"

Investors already hold emerging market equities in their portfolios, and according to the FT, investors might feel that these equity positions suffice for currency exposure.

I have been wondering lately if the sagging value of the dollar is actually going down through economic gyrations or being pushed down by design.

There are many repercussions. No one less than Rodrigo Rato, head of the International Monetary Fund, warned Monday of a potential "abrupt fall" in the US dollar that could roil the global economy. "There are risks that an abrupt fall in the dollar could either be triggered by, or itself trigger, a loss of confidence in dollar assets," Rato said at the close of annual meetings here of the IMF and the World Bank, according to news reports.

Here is what is really on his mind: Europe may take steps to temper the strong appreciation of the Euro, which is weighing on exports from the 13-nation bloc. "There is a risk that exchange rate appreciation in countries with flexible exchange rates -- including the Euro area -- could hurt their growth prospects, and that in these circumstances protectionist pressures could worsen," he said.

From my perspective I have wondered if the Bush administration is at least applauding the weak dollar as it improves U.S. trade imbalances, helps prop up the stock market and worried investment bankers, and strengthens American companies in many regards.

Contrary to expectations, the dollar has staged a strong rally in recent days. If history is any guide, a rising greenback will also have implications for U.S. share prices.

According to Bloomberg, the recent uptick has been spurred by "a worldwide rush for dollars as banks and fund managers scramble to pay back loans used to buy risky mortgage securities." Short-covering by bearish speculators has added further fuel to the fire.

Given the impact that currency moves can have on cross-border investment flows and the bottom lines of publicly-listed U.S. companies, many of which have significant exposure to export markets, it makes sense to try and figure out which sectors may benefit from further dollar appreciation and which may lose out.

More than a few optimistic reports have been written as the Dow Jones Industrial Average (DJIA) continues to climb to new highs. Given my value perspective and having run a few stock screens, some of the 30 stocks in the Dow have actually floated to the top. I will be reviewing the entire Dow in search of deep value and summarizing on my top three (10%) from a value perspective. The following is my view of the first five Dow stocks.

3M Company (NYSE: MMM) appears to be fairly valued from my perspective. I like the low debt ratio of 0.3 and higher than average yield of 2.19%. Given the price-to-book of 5.94 though, I think 3M will have to continue to expand its earnings overseas to interest me further. This is a quality stock, with good margins and good returns on equity, assets, and investment that are all higher than its lower than average P/E of 15. I view this stock as a good investment but not a great investment, and one that provides some downside protection.

Alcoa Aluminum (NYSE: AA) is on everyone's watch list, and for good reason. It reminds me of a line from the long-running TV show Married with Children, where Al Bundy shouts out to his wife Peg after a long day at the shoe store, "Either feed me, or feed me to something, I just want to be part of the food chain." There have been rumors galore that Alcoa might fall prey to a buyout from BHP Billiton Ltd ADR (NYSE: BHP) or another large player wanting to expand its North American presence. In the meantime, Alcoa has announced that it has an interest in acquiring Alcan Aluminum (NYSE: AL).

At 2.28, the price-to-book ratio of Alcoa is less than half that of 3M, and the price-to-sales is half too at 1.14. The debt levels are low and the price-to-cash-flow is low. Alcoa pays a lower than average (for the DJIA) yield of 1.75, but still respectable. For whatever reason, investors may be looking for soft pricing in aluminum related to concerns about a slowing world economy. While this may be a concern in the U.S., international growth does not seem to be slowing down. Alcoa is up about 35% from last year's lows, but only a couple of dollars from its highs of two years ago, so its path has been erratic. The low metrics, expanding international markets, and the high probability of consolidation in the market should create future pricing power. This does seem like a value play to me.
