NEW YORK ( TheStreet) -- Welcome to Don Dion's "Daily ETF Winners and Losers." Be sure to stop by each day to find out which ETFs are gaining or losing.

Winners

iShares Silver Trust ( SLV) 2.2%

ETFs related to the precious metals industry are seeing strength as we approach the weekend.

SLV may be interesting to watch in the days ahead. The fund is currently testing its 50-day moving average. This level has stood out as a point of support on a number of occasions over the past few months.

iShares Dow Jones U.S. Aerospace & Defense Index Fund ( ITA) 1.3%

The aerospace and defense industry has seen some welcomed strength as indicated by ITA's five-day streak of gains. On Friday, holdings including Goodrich ( GR) and Rockwell Collins ( COL) were leaders. In early afternoon trading, they were up over 6% and 9% respectively.

Losers

Market Vectors Vietnam ETF ( VNM) -4.0%

Vietnam's marketplace is taking a heavy hit, closing out a shaky week. With Friday's decline, VNM has given back all of its early September gains and is once again testing its 50-day moving average.

While VNM is struggling, the same cannot be said for other emerging Asian nations. The iShares MSCI Indonesia Investable Market Index Fund ( EIDO) is actually seeing some of the ETF industry's strongest action.

iPath Dow Jones UBS Sugar Subindex Total Return ETN ( SGG) -5.5%

Sugar prices are tumbling, leading the futures-backed SGG ETN to notable losses. The Wall Street Journal notes that signs of increasing production from Brazil are helping to place pressure on the sweetener.

At the start of next week, Teucrium is slated to launch the Teucrium Sugar Fund. The product will trade under the ticker symbol, CANE. This firm has seen success with other products, such as the Teucrium Corn Fund ( CORN) (CORN) so it will be interesting to see if its new funds can gather steam.

iShares Dow Jones North American Technology-Multimedia Networking Index Fund ( IGN) -2.6%

After four consecutive days of gains IGN appears to be taking breather, weighed down by Research in Motion ( RIMM). The fund's mutli-day rally helped it recover back to its 50-day moving average. This is a level to watch in the near term. Throughout 2011, it's been a point of resistance.
