When researching a stock like AT and T, 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 T 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 T 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 T 200 day moving average ("T 200 DMA"), while one of the most popular "shorter look-backs" is the T 50 day moving average ("T 50 DMA"). A chart showing both of these popular moving averages is shown on this page for AT and T. Comparing two moving averages against each other can be a useful visualization tool: by calculating the difference between the T 200 DMA and the T 50 DMA, we get a moving average convergence divergence indicator ("T MACD"). The T 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).
