European stocks will certainly see some volatility and the eurozone economy will face pressure in the short term as the Continent comes to grips with the terror attacks in Paris. Over the long run, however, European markets will improve as commerce resumes, says Christopher Gannatti, associate director of research at WisdomTree Investments.

"Historically, markets and economies have displayed a certain resilience,"  says Gannatti. "They have always come back. They have always ultimately recovered, and we think the Europeans will recover from this tragedy as well."

Gannatti suggests investors seeking long-term exposure to Europe try the recently launched WisdomTree Europe Local RecoveryETF (EZR) . The EZR seeks to track investment results of European companies sensitive to economic growth prospects in the eurozone and that derive more than 50% of their revenue from Europe. The top holdings in the EZR include Total (TOT) - Get Report , BASF  , Allianz (AZSEY) , BNP Paribas (BNPQY) and AXA  (AXAHY) .

"If ultimately the quantitative easing policy is to work, and Europe is to recover, what you want is a greater sensitivity at times to what's going on inside Europe," he says.

The Paris attacks also caused the dollar to further strengthen against the euro. In fact, the dollar has gained significantly against the European currency in the past month, rising from $1.13 per euro in mid-October to $1.06 today, primarily due to speculation that the Federal Reserve will institute a rate hike next month.

Gannatti suggests that those seeking to play this trend should opt for the Wisdomtree Strong Dollar U.S. Equity Fund (USSD) , which was launched this past summer. The fund seeks to track investment results of U.S. companies while maximizing exposure to companies with significant revenue from within the United States that may be less vulnerable to a strengthening U.S. dollar. Its top holdings include Verizon (VZ) - Get Report , AT&T (T) - Get Report , Comcast (CMCSA) - Get Report , Home Depot  (HD) - Get Reportand Wells Fargo (WFC) - Get Report .

"We track an index where at least 80% of the revenue of every constituent comes from inside the U.S.," adds Gannatti, "and you are really playing into the strength of the U.S. consumer, which is ultimately helped as the dollar goes up."
