When researching a stock like Alaska Air Group, many investors are the most familiar with Fundamental Analysis — looking at a company's balance sheet, earnings, revenues, and what's happening in that company's underlying business. Investors who use Fundamental Analysis to identify good stocks to buy or sell can also benefit from ALK Technical Analysis to help find a good entry or exit point. Technical Analysis is blind to the fundamentals and looks only at the trading data for ALK stock — the real life supply and demand for the stock over time — and examines that data in different ways. One of those ways is to calculate a Simpe Moving Average ("SMA") by looking back a certain number of days. One of the most popular "longer look-backs" is the ALK 200 day moving average ("ALK 200 DMA"), while one of the most popular "shorter look-backs" is the ALK 50 day moving average ("ALK 50 DMA"). A chart showing both of these popular moving averages is shown on this page for Alaska Air Group. Comparing two moving averages against each other can be a useful visualization tool: by calculating the difference between the ALK 200 DMA and the ALK 50 DMA, we get a moving average convergence divergence indicator ("ALK MACD"). The ALK MACD chart, in conjunction with the chart of the moving averages, basically helps in visualizing how the moving averages are showing convergence (moving closer together), or divergence (moving farther apart).
