GILD - Ascending triangle. 
Bulkowski says,  
The theory behind ascending triangles is that they point the way to higher prices after an upward breakout. Testing shows they do breakout upward 64% of the time (as of 7/1/16). Unfortunately, experience has taught me to look elsewhere for a chart pattern to trade because ascending triangles often don't perform up to expectations. I found that price rises for a few days, perhaps 5% to 10% or so and then collapses.
