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) - Get Report

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) - Get Report

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) - Get Report

-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) - Get Report

is actually seeing some of the ETF industry's strongest action.

iPath Dow Jones UBS Sugar Subindex Total Return ETN

(SGG) - Get Report

-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) - Get Report

(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) - Get Report

-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.

iPath Dow Jones UBS Natural Gas Subindex Total Return ETN

(GAZ) - Get Report

-1.9%

Futures-backed natural gas prices are falling for a second day, leading both GAZ and the

United States Natural Gas Fund

(UNG) - Get Report

to losses. GAZ's retreat has left the fund trading at all-time lows. It will be interesting to see if these funds have further to fall in the days ahead.
