NEW YORK ( TheStreet) -- Welcome to Don Dion's "ETF Winners and Losers." Be sure to stop by throughout the week to find out which ETFs are gaining or losing.
iPath S&P 500 VIX Short Term Futures ETN ( VXX) 2.8% The U.S. markets are starting off the week on a shaky note as European economic issues reignite investor fears and drive many into safe haven asset classes. The fear-tracking VIX index is reveling in today's jitters, helping it recapture some of the losses suffered during last week's late week sell-off. The VXX is in the process of testing its 50-day moving average. iShares Barclays 20+ Year Treasury Bond Fund ( TLT) 1.2% Long-term U.S. treasuries are falling into favor as markets head lower and investors seek out protection against looming macroeconomic headwinds. TLT's 50-day moving average may be a point to watch in the near term. This level appears to have become a point of support. It will be interesting to see if it holds up in the days ahead. iPath Dow Jones UBS Copper Subindex Total Return ETN ( JJC) 0.4% Despite the market's losses, copper prices are witnessing strength, indicated by the upward action seen from JJC. The fund's two-day climb has helped it recover to its 50-day moving average. This point should prove interesting, because the fund has struggled to break through during the first two weeks of this month.
Guggenheim Solar ETF ( TAN) -4.3% The solar energy sector has failed to capitalize on the gains from Friday's trading. Heading into the middle of the month, shares of TAN have given back any upward action. While TAN remains above its all-time lows, it will be interesting to see if it can stay buoyed in the face of ongoing economic concerns. Market Vectors Vietnam ETF ( VNM) -3.8% The Vietnam ETF is suffering heading into the new week as downward market action drives investors out of risky emerging markets. With these losses, shares of VNM have broken below previous 2011 lows. Continue to use caution when venturing into emerging markets. Any exposure should be kept small and closely monitored.
