Pre-September Selloff Hits ETFs

Stocks and many unleveraged exchanged-traded funds closed down Monday amid a rout in China's stock market, falling oil prices and concerns about key economic reports due later this week. Financial services and energy stocks were among the hardest hit, with ETFs for those sectors also losing ground.

The Dow Jones Industrial Average slipped 47 points to 9497. The S&P 500 declined 8 points to 1021 and the Nasdaq dropped 20 to 2009.

Heading into September, a notoriously bad month for stocks, the Dow industrials are up 8.75% for the year. Though trading volume has been light in recent days, the market has been able to hold on to a rally that sent the Dow up 12% since mid-July and up 45.8% from the March 9 low.

Economic data due later this week could be key to whether or not the markets hang onto those gains. On Tuesday the Institute for Supply Management will release its latest reading on U.S. factory activity. And Friday, the latest government reading on employment is due for release.

Defensive plays fared better in a mostly down trading session. The iShares Silver Trust fund (SLV) picked up 0.8% as investors headed for precious metals as a safe haven. Shares of the Consumer Staples Select Sector SPDR Fund (XLP) held their value, gaining 0.2%.

Declining oil prices hit the iPath S&P GSCI Crude Oil Total Return Index Medium-Term Note fund (OIL), pushing shares back 4.4%. The United States Oil fund (USO) dipped 4.1%. The SPDR S&P Metals & Mining fund (XME) declined 3.6% on commodity price drops.
