With Greece's public finance crisis raising pressing questions about the long-term viability of the eurozone in its present form, investors both individual and institutional are asking themselves if Europe is still a safe place to invest.

However, "Europe" covers wildly divergent economic realities (that's part of the problem), so investors who are looking for a blanket answer are doing themselves a disservice.

A brainteaser for global investors
Which of the following companies is more exposed to macroeconomic risks: Swedish mobile handset manufacturer LM Ericsson (Nasdaq: ERIC) or its U.S. competitor Motorola (NYSE: MOT)?

Surely the answer is Ericsson: A top European company, it must be heavily exposed to this brewing European crisis. But take a look at the following table:

 

LM Ericsson

Motorola

92.4%

Do you want to change your answer? Sweden's national currency is the krona, not the euro; furthermore, Sweden's public finances are in much better shape than ours. Finally, the eurozone accounted for less than a fifth of Ericsson's revenues in 2009.

No tricks, just four more examples
It may be true that Sweden is unrepresentative of the European market. But let's take a look at some of the same country data as it relates to companies that are headquartered in the eurozone:

 

Siemens AG (NYSE: SI), Deutsche Telekom (NYSE: DT), SAP (NYSE: SAP)

Nokia (NYSE: NOK)

Novo Nordisk (NYSE: NVO)

By these two measures, Germany, Sweden, and Denmark are all on a sounder fiscal footing than the U.S.; without further analysis, it would be hard to assert with any confidence that the three companies in the above table carry greater macroeconomic risk than any large-cap U.S. company.

Admittedly, the U.S. enjoys unparalleled flexibility in terms of its ability to fund its deficits, but I think these examples show that broad statements about "European stocks" or "the eurozone" aren't that useful for investors.

Macro- doesn't translate uniformly to micro-
Although the headline risk is macroeconomic -- the crisis relates to deteriorating public finances and to trade and consumption imbalances in the eurozone -- it won't have a uniform impact on different European countries, much less on different companies within those countries.

Despite this, it appears that many institutional investors aren't hanging around to work out the distinctions. In particular, asset allocators -- whose decision-making process is largely driven by macro considerations -- have already begun to lower their exposure to Europe.

According to a survey performed by Bank of America Merrill Lynch, between March 5 and March 11, 21% of asset allocators are underweight European equities, a steep increase from January, when 2% were overweight.

Sweeping shifts can create opportunity
For stockpickers, large money flows driven by sweeping shifts in sentiment can be a source of opportunity.

Not all European stocks have the same exposure to the current crisis; if institutional investors are reducing their exposure to Europe across the board, the resulting gap in demand for shares could create produce attractive equity valuations for high-quality companies.

However, such opportunities aren't free -- only investors who are knowledgeable and prepared will be able to identify them in time.
