Bullish Case: CIEN has bounced 8.2% off last week's $340.5 low and holds a 5% bullish-over-bearish risk skew across tenors. The 2029 roadmap with bullish analyst ratings (Sep 20) plus intact AI/cloud optical demand suggest the -24% 90-day drop was overdone. Helium's term structure prices near-term vol well below market (49-56% vs 62-68%), implying Helium sees less downside than options imply — supporting mean reversion toward $390-420.

Bearish Case: The stock fell despite a Q3 beat (Sep 3), sits below its 200-day MA with MACD sell signals and bearish money flow, and puts traded 171% more volume than calls. Heavy $340-370 put activity and elevated near-dated IV (89.6% at Sep 26 per market surface) show hedging demand. A 608% five-year run leaves valuation fragile; $270/$220 supports imply deep downside if AI optics sentiment cracks.

Potential Outcomes:

1. 40%: Range $340-395; post-earnings IV decays from ~68% toward Helium's ~50-56% curve (falsified by IV staying >70%).
2. 25%: Rally to $395-430 on roadmap/backlog momentum (falsified by rejection at $390 with put skew steepening).
3. 20%: Pullback to $305-340 as bearish technicals persist (confirmed by closes <340 with rising IV).
4. 10%: >12% shock either way; market PDF shows fat left tail at 220-260.
5. 5%: >$450 squeeze on short-covering.
