DETAILED ANALYSIS

3-6 month opportunity — emerging trend. Momentum (74) and Technical (50) are the primary strengths. I note that fundamentals is the weakest area at 15/100 — this warrants monitoring. Historical volatility is elevated at 50%. I classify this as a speculative position — elevated volatility at 50% and smaller market cap define the opportunity.
