As of April 19, 2026, 12:42 a.m. EDT: Options positioned are mixed but weighted towards call protection and momentum. In June 2026 calls, there is heavy Open Interest (OI) at strikes $25.0 and $30.0, suggesting a bullish bias or strategic positioning for upside. However, Put OI at $22.5 and $25.0 indicates a 'stop loss' or risk-off tortoise position at levels well below the current price of $22.88. The skew suggests speculators view a decline to $22.50 as a significant risk, while $25.00 is seen as the resistance level where options sellers are hedging. Put IV is elevated (~0.91) compared to Calls (~0.0), implying the market fears a sharper downside move than an upside one.
