U.S. equities staggered into Tuesday’s closing bell as exchange traded funds indexed to the S&P 500 lost 2.6% and fell below a key technical level.

Broad-based stock ETFs such as SPDR S&P 500 ETF (NYSEArca: SPY) and iShares S&P 500 (NYSEArca: IVV) sliced through their 200-day moving average in Tuesday’s sell-off.

The Dow shed 266 points with the Eurozone debt crisis and a potential U.S. credit ratings downgrade weighing on sentiment.

The S&P 500’s price level is now in negative territory for the year. The “risk-off” trade was in full force Tuesday.

In ETFs, investors sought the safety of funds tracking gold, the Swiss franc and U.S. Treasury bonds, for example. Exchange traded products tracking CBOE Volatility Index futures also rose Tuesday on the fear trade.
