FBIO Plummets 3.26% Amid FDA Setback—Is This a Buying Opportunity or a Warning Sign?

Summary
• Fortress Biotech (FBIO) tumbles 3.26% to $2.815, its lowest since October 2025
• FDA issues Complete Response Letter for CUTX-101, citing manufacturing deficiencies
• Options chain surges with 115 contracts traded for the November 21 $2.5 call

Fortress Biotech’s stock is in freefall as the FDA’s regulatory hurdle for CUTX-101 triggers a sharp selloff. With the stock trading below its 200-day moving average and RSI at 40, the market is pricing in a prolonged recovery. The biotech sector remains volatile, but FBIO’s 30-day support/resistance levels and options activity suggest a pivotal moment for traders.

FDA CRL Sparks Sharp Selloff in FBIO
The FDA’s Complete Response Letter for CUTX-101, issued on October 1, 2025, triggered an immediate 30% premarket drop and a 3.26% intraday decline. The CRL cited manufacturing facility deficiencies under cGMP standards, not clinical efficacy or safety concerns. This regulatory setback has forced investors to reassess the timeline for approval, eroding $150M in market cap. The stock’s collapse reflects the sector’s sensitivity to manufacturing compliance risks, particularly for small-cap biotechs reliant on single-asset pipelines.

Options Playbook: Leveraging Volatility in a Bearish FBIO
• 200-day average: 2.03875 (below current price)
• RSI: 40.0 (oversold)
• MACD: 0.00059 (bearish divergence)
• Bollinger Bands: Price at 2.581 (lower band)

FBIO’s technicals signal a short-term bearish bias, with RSI at oversold levels and MACD histogram negative. The 200-day MA at 2.03875 and Bollinger lower band at 2.581 form a critical support cluster. A 5% downside scenario to $2.674 would test this zone. For options, the FBIO20251121P2.5 put and FBIO20251121C2.5 call stand out. The put offers 10.39% leverage with 112.5% IV and a delta of -0.307, ideal for a bearish play. The call, with 4.68% leverage and 116.17% IV, provides upside potential if the stock rebounds. Both contracts have high turnover (6875 and 6875) and theta decay of -0.005785/-0.003314, amplifying gains in a volatile environment. Aggressive traders may consider the FBIO20251121P2.5 into a breakdown below $2.5, while bulls could target a bounce above $2.89 with the FBIO20251121C2.5.

Price series used: daily close (default for event studies). 2. Event window: ±30 trading days, a commonly accepted horizon to capture short- to medium-term drift when the user did not specify one. 3.

FBIO at a Crossroads—Act Now Before the Next Move
The FDA’s CRL has created a critical inflection point for FBIO, with the stock’s near-term fate hinging on Sentynl Therapeutics’ ability to address manufacturing issues. While the 30-day support at $2.581 and 200D MA at $2.03875 offer potential floors, the sector’s volatility demands caution. Amgen (AMGN), the sector leader, is up 0.15%, highlighting the contrast between diversified giants and single-asset biotechs. Traders should monitor the November 21 options expiration and Sentynl’s FDA meeting updates. A breakdown below $2.581 would validate the bear case, while a rebound above $2.89 could signal a short-covering rally. Position now with the FBIO20251121P2.5 for downside protection or the FBIO20251121C2.5 for a bullish breakout.
