The strongest three-month rally in four years by the Dow Jones industrial average has pushed the benchmark above the eye-catching 18,000 level this week. More importantly for some technical analysts, the Dow on Tuesday formed a so-called golden cross pattern, a technical indicator often associated with further gains ahead.

Since reaching a low on Jan. 20, the blue chip index is up nearly 15 percent, its strongest gain over a similar time frame since early 2012. The golden cross was formed when the Dow's 50-day moving average climbed above the 200-day moving average Tuesday, a move that analysts say could signal the start of a longer trend.
