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