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

iPath S&P 500 VIX Short Term Futures ETN

(VXX) - Get Report

5.0%

The markets are taking a shot across the bow today as we head towards the week's close. In return the VIX-tracking ETNs are among the few ETFs treading in positive territory.

The VXX has shown signs of leveling out over the past week and even ended the week in positive territory. Still, long-term investors should not try their luck with this product.

Losers

iPath Dow Jones UBS Sugar Total Return Subindex ETN

(SGG) - Get Report

-10.0%

Sugar prices are tumbling for the second consecutive day, weighing on SGG. Today's weakness can be attributed to reports that India is slated to produce a surplus of the sweetener.

SGG's crash over the past two days highlights the volatile nature of single commodity ETNs. Investors looking for a more solid way to play agricultural futures products should look to funds such as

PowerShares DB Agriculture Fund

(DBA) - Get Report

, which tracks a basket of various futures contracts.

Market Vectors China ETF

(PEK) - Get Report

-5.3%

The weakness in the China's marketplace is being blamed for struggling markets around the world today. While China is tumbling the hardest, other emerging market-focused ETFs are feeling pain as well. Non China-related ETF decliners include

WisdomTree India Earnings ETF

(EPI) - Get Report

and

iShares MSCI South Korea Index Fund

(EWY) - Get Report

.

I would not advise investors looking for China exposure to choose PEK. Though designed to reflect the performance of China A-Shares, PEK does not actually track a basket of stocks.

Rather, the fund uses derivatives to mimic the index's performance. The popularity of the fund has lead to the development of a substantial premium which is skewing its performance. When this premium is wiped out, investors will be sent for a loop.

Global X Silver Miners ETF

(SIL) - Get Report

-5.1%

Silver prices have powered higher for a handful of months as investors seek out exposure to precious metals in hopes of protecting against market volatility. On Friday, however the metal ran into a roadblock, resulting in losses for both miners and physically-based products.

ETFS Physical Platinum Shares (PPLT) was another notable tumbler.

Market Vectors Coal ETF

(KOL) - Get Report

-4.2%

Coal is taking a hit as shaky markets weigh on investor sentiment. Despite today's downturn, I wouldn't advise investors to take KOL off their radar. Given the strong growth outlooks from the emerging markets and the ongoing economic healing facing many regions of the globe, energy demand still looks promising. Coal will be a staple resource in powering the economic recovery.
