Here's a look at the best and worst performing ETFs of the past week.

Winners

Market Vectors Steel ( SLX) +14.6%

Claymore/Delta Global Shipping ( SEA) +11.2%

Market Vectors Coal ( KOL) +12.7%

First Trust ISE-Revere Natural Gas ( FCG) +12.2%

The global risk trade came back in force this week after commodity-related ETFs had sold off between mid-June and mid-July. Energy and industrial commodity prices bounced off their lows, and strong GDP reports from Singapore and China gave confidence to investors. These four funds are still down between 10% and 15% from their June 11 levels, however.

Claymore/Robb Report Global Luxury ( ROB) + 12%

With Goldman Sachs ( GS), JPMorgan Chase ( JPM) and other banks reporting knockout quarters, big bonuses may be on the way, and that's good news for luxury retailers. The fund has been unpopular though, and actually had zero volume on Friday. I picked it as one of the five dumbest ETFs, and it has no chance to attract attention until people begin wasting money again, something that doesn't happen until well into an economic upswing.

SPDR S&P Homebuilders ( XHB) +12.6%

iShares Dow Jones U.S. Home Construction ( ITB) +14.2%

Both these funds gained on Friday, while the broader real estate ETFs declined. This goes to my argument that recent housing news paints a brighter picture for homebuilders than for ETFs holding commercial real estate, although both face a difficult road ahead. iShares Dow Jones U.S. Real Estate ( IYR) gained 7.6% on the week.

Losers

iShares Barclays 20+ Year Treasury ( TLT) -5.2%

iShares Barclays 10-20 Year Treasury ( TLH) -3.4 %

SPDR Long Term Treasury ( TLO) -4.2%

PowerShares 1-30 Laddered Treasury ( PLW) -3.2%

It's risk up and safety down. Investors headed for the equity markets, and bonds had to offer higher yields to attract them. Expect more weeks such as this one if the market can rally another leg up from these levels.

WisdomTree Japan Small Cap ( DFJ) -1.6%

iShares Japan Small Cap ( SCJ) -1.5%

CurrencyShares Japanese Yen ( FXY) -2.1%

There were few equity funds down last week, given that the S&P 500 increased 7% on the week. Of the small number of losers, only Japanese small-caps and the yen were similar. Most of the loss came courtesy of the yen, which lost 2.1% as measured by FXY. The Nikkei managed only a 1.2% gain for the week, which was erased by the fall in the yen. The U.S. Dollar Index lost ground as well, but its 1% loss was dwarfed by the rally in stocks.
