When the Canadian dollar rapidly appreciated against the greenback, currency-neutral funds became popular. But, as noted in an earlier post, the short performance history showed that these funds exhibited large tracking errors. For instance, the iShares CDN S&P 500 Index Fund (XSP) is a currency-neutral version of the iShares S&P 500 Index Fund (IVV). In 2006 and 2007, XSP trailed IVV’s return by 1.72% and 2.29%, respectively. Another example is the performance difference between the TD US Index (US$) e-Series Fund (TDB952) and the TD US Index Currency Neutral (TDB904). TDB904 trailed the returns of TDB952 by 1.8% in 2007 and 1.1% in 2006.

In 2008, the currency-neutral funds continued to trail the performance of comparable US dollar denominated funds. The total returns of XSP and IVV was -40.08% and -36.68%. In other words, XSP trailed IVV by a stunning 3.4% in 2008. The tracking error of TDB904 over TDB952 was better but still very high at 1.63%.

Investors interested in hedging their currency exposure should pay attention to the large tracking errors exhibited by currency-neutral funds, which are much greater than the MER differential between these funds.
