I recently received an email from a twenty-something investor asking for my opinion on the following asset allocation:

Developed Markets – EFA – 52.5%
Emerging Markets – VWO – 22.2%
Corporate Bonds – XCB – 7.8%
Materials – XMA – 17.4%

Usually, I am unable to offer an opinion on someone’s asset allocation because I don’t know enough about their ability and willingness to take risks. In this instance though, it is easy to notice that US equity markets are totally left out and developed and emerging markets are significantly over weighted. I also don’t know the rationale behind adding exposure to corporate bonds at the expense of short-term government bonds and a narrow sector like materials instead of a broad-market fund. My suspicion is that there is an element of performance chasing because these asset classes have posted excellent near-term returns.

ETFs and index funds are a good thing only if used properly. If you don’t have a proper asset allocation or if you chase performance or if you don’t invest for the long-term, indexing could end up being as harmful as active management.
