| Intuitive Surgical develops, manufactures, and markets the da Vinci® Surgical System and the Ion® endoluminal system. The systems consist of a surgeon console or consoles, a patient-side cart, a vision system, and proprietary instruments and accessories. Co.'s technology is designed to provide surgeons with a range of articulation of the surgical instruments used in the surgical field analogous to the motions of a human wrist, while filtering out the tremor inherent in a surgeon's hand. Co.'s platform for robotic-assisted surgery, da Vinci Surgical System, allows surgeons to operate while seated at a ergonomic console viewing a three-dimensional, high definition image of the surgical field.
When researching a stock like Intuitive Surgical, 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 ISRG 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 ISRG 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 ISRG 200 day moving average ("ISRG 200 DMA"), while one of the most popular "shorter look-backs" is the ISRG 50 day moving average ("ISRG 50 DMA"). A chart showing both of these popular moving averages is shown on this page for Intuitive Surgical. Comparing two moving averages against each other can be a useful visualization tool: by calculating the difference between the ISRG 200 DMA and the ISRG 50 DMA, we get a moving average convergence divergence indicator ("ISRG MACD"). The ISRG 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).
