Market volatility likely to continue into this week

US stocks endured the most volatile week since November 2011 as traders lurched in and out of the market amid fears about the global economic recovery, Federal Reserve policy and the future of the US shale boom.

The volatility is likely to persist this week unless bank earnings or retail sales can exceed high expectations.

The Dow Jones Industrial Average fell almost 272 points on Tuesday, only to rally 274 points on Wednesday - Dow's biggest point gain of the year. It was immediately followed by the biggest point loss of the year on Thursday, a 335-point rout. In all, the Dow travelled more than 1,000 points in the five sessions. That's one of the biggest rides in the index's history on a dollar-for-dollar basis.
