It doesn't take a genius to figure out that the stocks an ETF tracks are selected by what stocks are members of the index that the ETF is supposed to mirror. So maybe we're being a little picky here and perhaps we should pick on the index designers not the ETF issuers, but here are four country-specific ETFs that could do with some rebalancing. 1) iShares MSCI Canada Index Fund (NYSE:

): Potash (NYSE:

), the world's largest fertilizer producer, is a top-10 holding, but only accounts for 3.5% of EWC. Agrium (NYSE:

) doesn't even crack the top-10 holdings. Less banks, more fertilizer please. 2) iShares MSCI Brazil Index Fund (NYSE:

): This one is simple: More Vale (NYSE:

), less Petrobras (NYSE:

), please. 3) iShares MSCI Switzerland Index Fund (NYSE:

): Yeah, it's kind of shady that Transocean calls Switzerland home, but that is the company's official headquarters, yet the stock is nowhere to be found in EWL. 4) iShares MSCI Netherlands Investable Market Index Fund (NYSE:

): Royal Dutch Shell (NYSE: RDS-A), Europe's largest company is based in the Netherlands, but isn't found among EWN's top-10 holdings, but it is a big part of the comparable U.K.-specific ETF. Go figure.
