How to invest in international ETFs
Start by deciding which type of international ETF you want to buy. Most stock brokers will have plenty of options available. If you want to get the broadest coverage possible, you could go with a total international stock market ETF that invests around the world, excluding the U.S. You could also get an ETF for emerging markets, developed markets, or a specific region, such as Europe or the Pacific.
Make sure to check the expense ratio before you invest. As a general rule, a good expense ratio for an ETF is 0.20% or lower. A higher fee doesn't necessarily mean you need to rule out an ETF, especially if it's actively managed, but you may want to look around to see if there's a more affordable alternative available.
You'll also need to decide how much of your portfolio you want to allocate toward international investments. Advice on this subject varies. Investing giant Vanguard recommends having at least 20% of your portfolio in international stocks, while Charles Schwab (SCHW -2.54%) suggests 5% to 25%.
