Here is the ETF Professor's ETF Watch List for Tuesday June 29, 2010. Steel stocks continue to look weak, so keep an eye on the Market Vectors Steel ETF SLX. Along those same lines, watch the SPDR S&P Metals & Mining ETF XME. The iShares MSCI Switzerland Index EWL was up almost 5% on Monday. Play another pullback in gold with the UltraShort Gold ProShares GLL. The UltraShort Silver ProShares ZSL is also worth a look. The Market Vectors Coal ETF KOL was down more than 3% on Monday. Currency play of the day: CurrencyShares Swiss Franc Trust FXF. With a lack of conviction for emerging markets, try the Ultra MSCI Emerging Markets ProShares EET.
