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

Winners

United States Natural Gas Fund ( UNG) 4.0%

Futures-based natural gas ETFs are leading the industry higher after the Energy Information Administration released a strong storage report.

The iPath Dow Jones UBS Natural Gas Subindex ETN ( GAZ) is seeing gains. This fund continues to boast a substantial premium that will cause the fund to trade out of line with its underlying assets. As of April 27 it stood at 10.5%.

iShares MSCI Japan Index Fund ( EWJ) 2.2%

Although the nation's marketplace remains volatile in the aftermath following the devastating earthquake and tsunami, Japan-linked ETFs are among some of the industry's biggest gainers today.

Japan-based companies including Kyocera and Panasonic have witnessed strength recently. Both can be found among EWJ's index.

SPDR KBW Insurance ETF ( KIE) 1.9%

A number of leading insurance providers offered up strong earnings results recently, proving KIE with some fuel to power higher.

Allstate ( ALL), Aflac ( AFL) and Lincoln National Corporation ( LNC) are among the sector's biggest movers. All three are up over 4% in early afternoon trading.

Losers

Teucrium Corn ETF ( CORN) -5.0%

Corn prices are being pressured today, leading CORN to losses. With today's downturn, CORN has retreated back to its 50-day moving average.

Other grains-heavy funds such as the iPath Dow Jones UBS Grains Subindex Total Return ETN ( JJG) and the iPath Dow Jones UBS Agriculture Subindex Total Return ETN ( JJA) are sliding as well.

The iPath Dow Jones UBS Sugar Subindex Total Return ETN ( SGG) is falling as we head towards the close. The fund is now trading at levels last seen in October, 2010.
