Dion's Weekly ETF Winners and Losers

NEW YORK (TheStreet) -- Here are this week's winners and losers.

Winners

iPath Dow Jones UBS Sugar Subindex Total Return ETN (SGG) 4.2%

Sugar prices marched higher this week, helping SGG break through its 50-day moving average for the first time since the start of March. Looking to the near term, it will be interesting to see if the fund's recent spurt of upward action is a sign that its multi-month losing streak is over.

Although SGG may be exciting to watch, I urge investors to look to other more diversifided options like PowerShares DB Agriculture Fund (DBA).

United States Natural Gas Fund (UNG) 3.9%

The futures-tracking UNG has had an impressive run over the past few weeks, breaking through both its 50- and 200-day moving averages.

This week, an encouraging storage report from the Energy Information Administration played a big role in sending the fund higher.

I continue to monitor the performance of the fellow natural gas futures-backed product, the iPath Dow Jones UBS Natural Gas Subindex ETN (GAZ). In the past, the fund has been heavily influenced by a substantial premium.

Market Vectors Vietnam ETF (VNM) 2.1%

Although it took a hit on Friday, the Vietnam ETF still managed to close out this shortened week with some industry leading gains. The upward action was welcomed and has helped VNM recover some of the losses it suffered during its steep, eight-day slide during the latter half of May.

Emerging market ETFs could prove risky in the coming days as choppy market action weighs on investor sentiment. Given its wild performance over the past few weeks, conservative investors may want to steer clear of VNM.

Losers

iShares Silver Trust (SLV) -4.6%

SLV sat at the top of last week's weekly winners and losers list. This week, however, the fund struggled to capitalize.

SLV started the week on a strong note. However, for the second time, the physically-based fund's ascension was halted by its 50-day moving average. Looking to the near term, this level will continue to be interesting to watch.

The precious metals industry could fall into favor in the coming weeks in the event that market turmoil drives investors to protective assets.
