S&P 500 closes in an official 'death cross,' a chart pattern that could signal more pain ahead

A scary chart pattern, called the 'death cross,' formed in the chart of the S&P 500 on Friday, signaling traders that there could be more selling ahead. The death cross formation appeared in the chart of the small cap Russell 2000 index just over three weeks ago, and the Russell has lost 4.4 percent since then. The death cross means the market could stay "lower for longer," said one technical strategist.
