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.

Winners

iPath Dow Jones UBS Grains Subindex Total Return ETN

(JJG) - Get Report

3.0%

Exchange traded products linked to the grains industry are heading higher at the start of the week. This marks the seventh consecutive day of gains for JJG. The rally has pushed the fund through its 50-day moving average for the first time since mid-September.

The corn-tracking

Teucrium Corn ETF

(CORN) - Get Report

is another agriculture-related product enjoying upward action.

United States Oil Fund

(USO) - Get Report

1.7%

Although the agriculture industry is leading the way, other futures-tracking commodity ETFs gaining ground as well. Oil funds are seeing particularly impressive strength. Both USO and the

United States Brent Oil Fund

(BNO) - Get Report

are up over 1%.

Others like the

United States Natural Gas Fund

(UNG) - Get Report

and

United States Gasoline Fund

(UGA) - Get Report

are largely unchanged.

Losers

Guggenheim Solar ETF

(TAN) - Get Report

-2.3%

The solar energy ETF enjoyed three solid days of upward action heading into the holiday weekend. This strength is proving to be fleeting, however, as TAN kicks off the shortened week on a sour note.

I've explained in the past that funds like TAN continue to face steep hurdles. This is not an ETF I would recommend at this time.

Market Vectors Vietnam ETF

(VNM) - Get Report

-3.3%

As investors kick off this shortened week of trading, emerging markets are being shunned. Asia is particularly unpopular, as indicated by the losses seen from VNM,

iShares MSCI South Korea Index Fund

(EWY) - Get Report

and

iShares MSCI Thailand Investable Market Index Fund

(THD) - Get Report

.

The

Guggenheim China Small Cap ETF

(HAO) - Get Report

is another notable loser.

Market Vectors Gold Miners ETF

(GDX) - Get Report

-1.5%

Precious metal miners are struggling to gain ground, pushing GDX and

Global X Silver Miners ETF

(SIL) - Get Report

to standout losses. Interestingly, although it is designed to target smaller, more-volatile names, the losses from the

Market Vectors Junior Gold Miners ETF

(GDXJ) - Get Report

are relatively contained.

iShares MSCI Chile Investable Market Index Fund

(ECH) - Get Report

-1.8%

While ETFs linked to Asian nations like Vietnam and Thailand are leading the way lower, South American funds are struggling as well. ECH and the

iShares MSCI Mexico Investable Market Index Fund

(EWW) - Get Report

are the biggest decliners.

This downturn comes after reports that South America-based emerging market leader Brazil has officially overtaken the U.K. as the world's sixth-largest economy.

The

iShares MSCI Brazil Index Fund

(EWZ) - Get Report

is relatively unchanged during early afternoon trading.
