Sirona Dental Systems ( SIRO) is a manufacturer of dental equipment. Sirona operates in three segments: Dental CAD/CAM Systems, Imaging Systems, Treatment Centers and Instruments. This stock is trading up 1% at $43.58 in recent trading. Today's Volume: 336,000 Average Volume: 428,542 Volume % Change: 50%. Shares of SIRO are moving modestly higher today after Robert W. Baird upgraded the stock to outperform from neutral. From a technical perspective, SIRO is moving modestly higher here with decent volume. This move is pushing the stock within range of triggering a near-term breakout trade. That trade will hit once SIRO takes out its 50-day moving average of $45.30, its 200-day moving average of $46 and some near-term overhead resistance at $46.59 with high volume. Traders should now look for long-biased trades once SIRO sustains a move or close above those levels with volume that's near or above 428,542 shares. If we get that action soon, then SIRO could spike higher towards $49 to $52 in the near future. On the flipside, I would avoid any long trades and possibly look for short trades if SIRO fails to clear both its 50-day and 200-day with solid volume.
