Investopedia explains ‘Wedge’
Once the price breaks out of the wedge, it is expected to return to the major trend. Technical analysts see a 'breakout' of this wedge pattern as either bullish (on a breakout above the upper line) or bearish (on a breakout below the lower line). A wedge shape pointing upwards (rising wedge) is used in analyzing an upward price trend within an overall downward price trend. A level wedge is considered a period of consolidation, which will not reverse the current major trend. Finally a wedge pointing downwards (falling wedge) is used to analyze a downward price trend within an overall upward price movement.
Please keep an eye on the volume, if the Volume exceeds more than 2,000,000 and NVS closes at least 1.5 to 2% above its new high $64.07, the stock will breakout and could move about 10% in the next six months.
