Mutual Funds vs. ETFs for my Roth IRA
I am going to start a Roth IRA and am a little confused between mutual funds and ETFs. I plan on buying and holding for the long term; which one would be cheaper?
My preference is for something aggressive and global/international, or maybe a global index. My reasoning is that various countries' stock markets have done very well in the past, eg, the Japanese stock market did much better than the U.S. market for a period of time, and if I invest in American funds I would be missing these trends, while if I invest in a global fund I have access to both American and international stocks.
Some of the global mutual funds I have looked at are Oppenheimer Global Opportunities and Oakmark Global.
What strategies have people used for international funds? Is there a such thing as a global index fund and how has it performed in the long run?
