When you compare the I fund to three other index mutual funds that are also to track the MSCI EAFE index, it appears that the I fund does a reasonably good job. However, given the lauded TSP low fees, shouldn't it be doing a better job, with less tracking error? I've asterisked the best fund in tracking the EAFE for each year for the past few years. Note that the I fund only came closest to the index in one year.
