NEW YORK ( TheStreet) -- Welcome to Don Dion's Daily ETF Winners and Losers. Be sure to stop by each day to find out who's winning and who's losing when it comes to ETFs.

Winners

Global X Uranium ETF ( URA) 3.0%

The troubled uranium ETF is heading higher, witnessing its third consecutive day of gains.

Shares of URA and Market Vectors Uranium+Nuclear Energy ETF ( NLR) continue to swing wildly from day to day. I would urge conservative investors to avoid this industry for now. Aggressive investors meanwhile should keep any exposure small and focused.

Guggenheim Solar ETF ( TAN) 2.9%

The solar energy ETF is surging following news that the industry bellwether and First Solar ( FSLR) had received loan guarantees from the U.S. Department of Energy totaling over $3.5 billion. FLSR accounts for nearly one-fifth of TAN's index.

Yingli Green Energy ( YGE) and Trina Solar ( TSL) are other big movers in the solar sector.

Looking ahead, investors should exhibit caution with TAN. Although it has enjoyed an impressive run up during the latter half of June, alternative energy remains a wildly volatile corner of the investing universe.

iShares MSCI Spain Index Fund ( EWP) 2.8%

Spain's markets have staged an impressive bounce over the past few days as tensions surrounding the Greek debt crisis have eased.

In the days and weeks ahead, EWP will be interesting to watch but I urge cautious investors to look elsewhere for Europe exposure. Sweden has stood out as a region of stability and can be accessed using the iShares MSCI Sweden Index Fund ( EWD).

First Trust ISE Global Copper Index Fund ( CU) 2.2%

Copper miners have enjoyed a welcomed bout of strength, pushing shares of CU along a four-day streak of gains. This upward action has helped the fund regain levels above its 50-day moving average. The last time shares of CU traded above this level was early May.

Losers

Teucrium Corn ETF ( CORN) -9.1%

Corn is taking a heavy shot across the bow, leading a wide collection of agriculture-related ETFs and ETNs into negative territory.

A storage report from the U.S. Department of Agriculture is spurring the sell-off. A Bloomberg noted that the agency found that corn stockpiles as of the start of June were 12% higher than expected
