We think conservative investors could hold up to 10% of their portfolios in foreign stocks. One way to do that is to buy carefully chosen exchange traded funds (ETFs) that have an overseas focus.

Here’s a look at four international ETFs we see as buys, and two we feel you should hang on to:

ISHARES MSCI EMERGING MARKETS INDEX FUND $31.82 (New York symbol EEM; buy or sell through brokers) aims to track the MSCI Emerging Markets Index.

The fund’s geographic breakdown includes China, 24.0%; South Korea, 15.3%; Taiwan, 12.8%; India, 8.0%; South Africa, 6.4%; Brazil, 5.7%; Mexico, 4.6%; Russia, 3.7%; Malaysia, 3.5%; Indonesia, 3.0%; Thailand, 2.3%; and Turkey, 1.5%.

Its top holdings are Samsung Electronics (South Korea), 3.8%; Taiwan Semiconductor (computer chips), 3.4%; Tencent Holdings (China: Internet), 2.9%; China Mobile, 2.0%; China Construction Bank, 1.5%; Naspers (South Africa: media and Internet), 1.5%; Industrial & Commercial Bank of China, 1.1%; and Hon Hai Precision (Taiwan), 1.0%.

iShares launched the ETF on April 7, 2003. Its expense ratio is 0.72%.

Emerging markets are still more volatile and vulnerable to economic downturns than developed nations. But this fund’s broad diversification among these countries tones down its risk.

iShares MSCI Emerging Markets Index Fund is a buy for aggressive investors.

ISHARES MSCI SOUTH KOREA INDEX FUND $48.28 (New York symbol EWY; buy or sell through brokers) aims to track the MSCI Korea Index. The ETF’s top holdings are Samsung Electronics, 21.2%; Hyundai Motor, 3.7%; SK Hynix Semiconductor, 2.9%; Hyundai Mobis (auto parts), 2.8%; Shinhan Financial, 2.7%; Naver (Internet), 2.6%; Korea Electric Power, 2.5%; LG Chemicals, 2.3%; Posco (steel), 2.2%; Kia Motors, 2.0%; AmorePacific Corp. (cosmetics), 2.0%; KT&G Corp. (tobacco), 1.9%; KB Financial, 1.9%; and Samsung Fire & Marine Insurance, 1.7%.

The iShares MSCI South Korea Index Fund was launched on May 9, 2000. Its expense ratio is 0.64%.

South Korea has Asia’s fourth-largest economy, after China, Japan and India. It is reliant on exports, but shipments to the U.S. are rebounding. That’s offsetting weak shipments to China.

The steady rise of South Korea’s currency, the won, hurt its economy in 2012 and 2013 by making its goods more expensive for foreign buyers. But South Korea cut interest rates to record lows, bringing the won down to five-year lows against the U.S. dollar. The move has boosted exports.

In the longer term, the country faces an aging population, with a birth rate of 1.2 children per woman—the lowest in the developed world.

The country ships about 25% of its exports to China, and weak demand there will hurt manufacturers. However, the U.S., Europe and Japan together account for a further 25% of exports. An improving outlook for them should offset the weakness in China.

South Korea’s economy will likely grow by 3.9% in 2016, and a big stimulus program and continued low oil prices could push that figure higher; South Korea imports almost all of its oil, bringing in the fifth-largest amount in the world, after Germany.

iShares MSCI South Korea Index Fund is a buy for aggressive investors.

ISHARES MSCI GERMANY FUND $24.22 (New York symbol EWG; buy or sell through brokers) tracks the stocks in the MSCI Germany Index.

This index aims to replicate 85% of the market capitalization of the German stock market. The remaining 15% is unavailable for investment, partly due to limitations on foreign ownership.

The ETF’s top holdings are Bayer (diversified chemicals), 8.8%; SAP (software), 7.5%; Siemens (engineering conglomerate), 7.4%; Allianz (insurance), 6.8%; Daimler (automobiles), 7.3%; BASF (chemicals), 6.1%; Deutsche Telekom, 5.4%; Munich Reinsurance, 3.3%; BMW AG, 2.7%; Linde AG (industrial gases), 2.6%; Fresenius (health care), 2.6%; Deutsche Bank AG, 2.4%; and Deutsche Post AG, 2.3%.

The ETF began trading on March 12, 1996. Its expense ratio is 0.48%.

Weak European markets slowed Germany’s growth last year, while ongoing sanctions against Russia continue to hurt German firms that have a significant number of Russian customers. However, the low euro remains a big plus for exports, and the long-term outlook for the German economy is sound.

iShares MSCI Germany Fund is a buy.

ISHARES MSCI CHILE INVESTABLE MARKET INDEX FUND $34.42 (New York symbol ECH; buy or sell through brokers) is an ETF that aims to track the MSCI Chile Investable Market Index, which consists of stocks that mainly trade on the Santiago Stock Exchange.

The fund’s largest holdings are Enersis SA (electricity), 10.3%; Empresa Nacional de Electricidad (electricity), 9.0%; Empresas Copec SA (conglomerate), 7.9%; S.A.C.I. Falabella (retail), 6.5%; Banco Santander Chile (banking), 5.8%; Cencosud SA (retailer), 5.8%; Empresas CMPC (pulp and paper), 4.7%; Colbun SA (utility), 4.6%; and Banco de Chile, 4.3%.

The ETF’s industry breakdown consists of Utilities, 31.9%; Financials, 19.5%; Materials, 13.0%; Consumer Staples, 9.7%; Energy, 8.2%; Consumer Discretionary, 8.0%; Industrials, 4.4%; Telecommunication services, 2.5%; and Information Technology, 2.1%.

The iShares MSCI Chile Investable Market Index Fund launched on November 12, 2007. It has a 0.64% expense ratio.

Chile is the world’s biggest copper producer and a major supplier to Asian markets. Its dependence on resources is something of a drawback to investment, particularly as Asian economies have slowed and copper prices have dropped sharply.

The country’s long-term outlook remains sound, but we see the iShares MSCI Chile Investable Market Index Fund as a hold.

ISHARES MSCI AUSTRALIA ETF $18.36 (New York symbol EWA; buy or sell through brokers) is an ETF that holds the 73 largest Australian stocks.

The fund’s top holdings include Commonwealth Bank of Australia, 11.2%; Westpac Banking Corp., 8.8%; National Australia Bank, 6.0%; Australia and New Zealand Banking Group, 6.0%; BHP Billiton, 4.7%; CSL Ltd., 4.4%; Wesfarmers, 4.2%; Woolworths Ltd., 2.6%; Scentre Group, 2.2%; and Transurban Group, 2.1%.

The ETF’s industry breakdown consists of Financials, 54.8%; Materials, 12.1%; Consumer Staples, 7.7%; Health Care, 6.5%; Industrials, 6.1%; Energy, 4.7%; Utilities, 2.6%; Consumer Discretionary, 2.4%; and Telecommunications, 2.3%.

The iShares MSCI Australia ETF was launched on March 12, 1996. It has a 0.48% expense ratio.

Australia benefits from its stable banking and political systems. It is also rich in natural resources. While low commodity prices have hurt the country’s economy, its proximity to Asian markets with vast potential, including India and China, gives it strong long-term prospects.

iShares MSCI Australia ETF is a buy.

ISHARES MSCI BRAZIL INDEX FUND $22.11 (New York symbol EWZ; buy or sell through brokers) is an ETF that’s designed to track the Brazilian stock market. Its top holdings are AmBev SA (beer and beverages), 10.8%; Cia Itau Unibanco Holding (banking), 10.0%; Banco Brandesco SA, 7.1%; Petrobras (oil and gas), 5.3%; BRF SA (food), 4.3%; Cielo SA (payment processing), 3.6%; Ultrapar SA (gas distribution and petrochemicals), 3.1%; and Itausa Investimentos SA (financial services), 2.9%.

iShares launched the ETF on July 10, 2000. It has a 0.64% expense ratio.

Sluggish exports and low resource prices continue to slow Brazil’s economic growth. State-controlled oil and gas giant Petrobras is also in the midst of a huge corruption scandal. As well, re-elected president Dilma Rousseff has yet to fulfill her promises of less growth-inhibiting government intervention in the economy.

Brazil still has strong long-term growth potential, but it needs to get its economy back on track.

iShares MSCI Brazil Index Fund is a hold.
