The world's stock markets posted mixed results Wednesday after a week of turmoil that saw steep losses and some recovery.

The major U.S. stock market indexes lost around three-tenths of a percent after rising oil prices discouraged traders.

European stock market indexes moved up two-tenths of a percent or more.

Dealers say many investors are concerned that the global market sell-off that began last week may resume. 

Earlier in Asia, major indices fell almost one percent in Mumbai and Hong Kong, while Tokyo was down half-a-percent at the close.
