Oklo's 8.2% Plunge: Insider Selloff and Goldman's Warning Spark Turbulence in Nuclear Energy's Hottest Stock

Summary
• Oklo (OKLO) tumbles 8.2% intraday to $109.36, erasing $10B in market cap
• Goldman Sachs initiates neutral rating, warning of 11% downside to $117
• CEO Jacob DeWitte and board members offload $18.1M in shares
• Stock trades between $108.54 and $119.90 amid regulatory uncertainty and unproven revenue model

Oklo's sharp selloff reflects investor anxiety over regulatory hurdles and unmet commercial milestones. With insider selling accelerating and Goldman Sachs flagging valuation risks, the nuclear energy pioneer faces a critical juncture as it seeks NRC approval for its Aurora Powerhouse. The stock's 52-week high of $144.49 now feels distant as technical indicators suggest a potential breakdown below key support levels.

Insider Selloff and Goldman's Neutral Rating Trigger OKLO's Sharp Decline
Oklo's 8.2% intraday drop stems from a perfect storm of insider selling and institutional skepticism. CEO Jacob DeWitte gifted $3M in shares, while director Michael Klein and CFO Craig Bealmear sold $6.7M and $9.4M respectively. Goldman Sachs' initiation of a neutral rating compounded the pressure, warning investors that Oklo's valuation appears 'full' and its business model requires 'de-risking.' The analyst highlighted the absence of finalized power purchase agreements and the capital-intensive nature of owning and operating nuclear plants as major risks. With the stock down 16% over two days and trading at a -234 P/E ratio, market participants are recalibrating expectations for the nuclear startup's path to commercialization.

Electric Utilities Sector Mixed as Oklo Diverges from Peers
While Oklo's 8.2% decline stands out, the broader Electric Utilities sector shows mixed performance. Sector leader NextEra Energy (NEE) trades up 1.24%, reflecting stability in established utility stocks. Oklo's volatility contrasts with the sector's defensive characteristics, as its unproven business model and regulatory uncertainties make it a speculative play rather than a core holding. The nuclear energy subset remains polarized, with investors weighing long-term decarbonization potential against Oklo's lack of revenue and regulatory delays.

Bearish Options Play and ETF Positioning in Volatile Nuclear Sector

• 30-day support: $73.13–$74.68 | 200-day support: $20.86–$23.34

Oklo's technical profile suggests a potential breakdown below $108.54 (intraday low), with RSI at 75.2 indicating overbought conditions. The stock's -234 P/E ratio and -8.2% intraday drop highlight extreme bearish momentum. Two options stand out for short-term bearish exposure:
