Sirona Dental Systems, Inc. ( SIRO ) recently jumped above a key level of resistance that had kept shares contained in a narrow range between $36.50 and $38 for the last two months. The push higher places shares just four cents away from the 52-week high at $39.35. If shares do close and trade above the level, it should then provide support on any weakness or a pullback. The MACD indicator below the chart is also looking bullish, with the short-term moving average in position to eclipse its longer-term counterpart. Take a look below. Domino's Pizza Co. ( DPZ ) has also been on the move, recently surging above a key level of its own to hit a new 52-week high at $15.64. Shares have since pulled back just a pinch, but look for support at $14 on any more weakness or profit taking. The MACD is bullish here too, with the short-term moving average trading above the long-term average. Zacks Investment Research
