Key takeaways
- Lumentum Holdings Inc. stock closed at 947.88, above the daily upper Bollinger Band at 944.54, on volume of 302,786 shares.
- Daily RSI sits at only 61.35, well below overbought, leaving room for further upside if the breakout holds.
- Hourly RSI at 76.09 and 15m RSI at 84.27 flag extreme short-term stretch, warning the easiest part of the move may be behind.
