NEW YORK ( ETF Expert) --Value-oriented thinkers have labored to persuade investors to invest in Europe for nearly three years.Specifically, they've pushed forward the idea that miraculously low price-to-book ratios offer compelling bargains in European ETFs, in spite of the ongoing sovereign debt crisis and negligible economic growth. However, deep-discount investing during financial crises is a recipe for failure. For example, by 2007, Bill Miller built Legg Mason Value into the largest mutual fund on the planet. Unfortunately, the guru chose to pack his luggage with banks and insurers. Miller stubbornly stood by his "call" throughout the collapse in 2008, pointing to exceptionally attractive valuations like low price-to-book ratios. In the end, shareholders watched in horror as minus 75% returns had evaporated their asset. Mr. Bill? He retired in reasonable comfort a year later. Granted, there are differences between the credit crunch of 2008 and Europe's sovereign debt mess. Yet, there are more similarities than many care to admit. We're still talking about major banks and insurers holding toxic debts (e..g, Greek two-year notes, Spanish bonds, etc.) that threaten the global financial system. Saving the European banks will require more and more "bailout euros," which is likely to erode the value of the currency in the near term. For this reason, I haven't had any direct exposure to Europe for several years. There's not enough diversification reasoning in the financial planning pot to persuade me that unhedged European ETFs are sensible risk-reward investments at this time. In contrast, Russ Koesterich, iShares' global chief investment strategist, is the latest individual to suggest adding some European flare. He is recommending iShares MSCI France ( EWQ). The reasons he cites include a price-to-book multiple of 1.14, a 31% discount to the MSCI World Index and a 15% discount to Germany. If we were able to rely on fundamentals alone, I might share Koesterich's assessment. Yet, France is a major component of a deepening recession in the region and the political leadership abhors capitalism. Moreover, a euro that depreciates against the dollar hurts EWQ's chances, and I see little evidence that the euro will strengthen over the next six months.
