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.


Global X Uranium ETF

(URA) - Get Report


Uranium producers are heading higher, pushing URA to a second day of gains. This strength is welcomed after the fund's steady downward path in the second half of November. The decline caused URA to erase nearly all of the gains from its October rally.

Other energy-related ETFs powering higher include the

Guggenheim Canadian Energy Income ETF


and the

First Trust ISE Revere Natural Gas Index Fund

(FCG) - Get Report


iShares MSCI South Korea Index Fund

(EWY) - Get Report


The U.S. markets are following up Monday's strong rally with mixed action. A diverse collection of emerging market ETFs are heading higher. EWY,

iShares MSCI Mexico Investable Market Index Fund

(EWW) - Get Report


Market Vectors Indonesia ETF

(IDX) - Get Report

are among the biggest movers.

iPath Dow Jones UBS Grains Subindex Total Return ETN

(JJG) - Get Report


Reignited confidence brought on by the market's upward action has helped to inject some strength back into the futures-linked grain ETN. The fund's climb has helped to snap its seven-day losing streak.

Not all products linked to agricultural futures contracts are seeing strength, however. The

iShares Dow Jones UBS Cocoa Subindex Total Return ETN

(NIB) - Get Report

is struggling to break out of negative territory.


PowerShares India Portfolio

(PIN) - Get Report


After two solid days of gains, India-related ETFs including PIN and

iShares S&P India Nifty 50 Index Fund

(INDY) - Get Report

are taking a breather, locking in noticeable losses.

November has been a rough month for this emerging market giant. It will be interesting to see if it can find some solid ground in December.

iShares MSCI South Africa Index Fund

(EZA) - Get Report


This is one of the ETF industry's biggest gainers during Monday's rally. However, the fund appears to be retreating as we approach the middle of the week.

A disappointing GDP reading in the third quarter is doing little to ignite confidence in South Africa. According to


, the nation grew 1.4% during the most recent three-month period. Analysts had been expecting a 1.8% increase.

iPath S&P 500 VIX Short Term Futures ETN

(VXX) - Get Report


For a second day, VIX-tracking ETFs are taking a hit as fear falls by the wayside. This retreat has sent VXX back to its 50-day moving average. Looking to the near term, it will be interesting to see if this level becomes a level of support.

Although the recent dose of strength has been encouraging, I urge investors to avoid getting carried away here. Excessive exposure to risk will leave an investor vulnerable to losses in the event that macroeconomic headwinds crop back up.

All prices as of 2:13 PM EST
