The chart says it all. If I wanted to guess at fundamental catalysts that would cause this, is Intel's continued delay of 10nm. Also, Intel's only competitor, AMD's chart is just breaking resistance of over a year of consolidation. I'm guessing AMD will be taking market share in a big way.
This is a simple short setup, nothing too overly complicated to explain here. Typically, wedges breakout to 100% of their height in the opposite direction.
