One of the strongest bullish indicators is the weekly ascending triangle and upstart digital storage provider, Pure Storage Inc. (PSTG) is primed for a breakout. PSTG is up 28% year-to-date and is up 21% over last one-year period. PSTG has admirable earnings momentum with back-to-back gains of 19% and 9.3% in Q1 and Q2 2017. This comes after three consecutive negative quarterly reports to end 2016. The stock is higher in just seven of the last 16 weeks including gains of 28.2% and 19.7% for the weeks ending May 26 and Aug. 25. The $15 level serves as strong resistance with no weekly closes above it since the end of 2015.

Recommendation: Enter PSTG with a buy stop above $15.20. Once this level is breached, PSTG could challenge its all-time high above $20 and would clear a long weekly cup base trigger of $20.70 dating back to its October 2015 debut. Place a protective stop at $14.
