Here is the ETF Professor's ETF Watch List for Wednesday June 30, 2010. Emerging markets were hammered on Tuesday with the iShares MSCI Brazil Index (NYSE: EWZ) losing 5%. That makes the UltraShort MSCI Brazil ProShares (NYSE: BZQ) worth watching. The Vanguard Emerging Markets Stock ETF (NYSE: VWO) was down more than 3% on Tuesday. Stay away from materials ETFs like the SPDR S&P Metals & Mining ETF (NYSE: XME), which was down more than 6% on Tuesday. Or embrace the UltraShort Basic Materials ProShares (NYSE: SMN). With Europe's woes dragging the market lower, trade the UltraShort Euro ProShares (NYSE: EUO). With tech looking bleak, put the UltraShort QQQ ProShares (NYSE: QID) on your list. With oil trading lower over night, track the PowerShares DB Crude Oil Double Short ETN (NYSE: DTO).
