Alaska Air (ALK) fell sharply in early June, established support just above 46 and bounced off this support zone the last few days. This is impressive considering the selling pressure that hit the market this week. Notice the hollow, or white, candles. These form when the close is well above the open, which means there was buying pressure during the day. The indicator window shows the StockCharts Technical Rank (SCTR) holding above 70 as ALK continues to show relative strength.
