As of April 18, 2026, 10:30 p.m. EDT: Options flow indicates high speculative positioning on upside, with significant OI and volume spikes at $350 and $450 strikes for near-term expirations. ATM nodes show elevated IV compression, particularly in July 2027, while deep ITM puts (e.g., $150 call covering bets) show inflated IV suggesting insurance hedges rather than directional puts. The expiry live-action around April 17 shows notable open interest concentration at $370, suggesting a floor at this level.
