Oruka Therapeutics (ORKA) Surges 10.6% on Breakthrough Phase 1 Data and Capital Raise Momentum

Summary
• Oruka Therapeutics (ORKA) rockets 10.6% to $28.21, hitting an intraday high of $29.20 after announcing positive Phase 1 trial results for ORKA-001
• Interim data reveals a 100-day half-life and favorable safety profile, positioning the drug for potential annual dosing in psoriasis
• A $200 million follow-on equity offering and analyst upgrades (Barclays: $48 target) amplify investor optimism

Oruka Therapeutics’ stock is surging on a perfect storm of clinical progress and capital-raising momentum. The biotech’s Phase 1 trial of ORKA-001, a long-acting IL-23p19 antibody, delivered a 100-day half-life and robust safety data, fueling expectations for a paradigm shift in psoriasis treatment. Meanwhile, a $200 million equity offering and analyst upgrades (Barclays’ $48 target) underscore growing confidence in the company’s ability to fund its ambitious clinical timeline.

Phase 1 Trial Breakthrough Ignites Investor Optimism
Oruka’s 10.6% intraday surge is directly tied to the release of interim Phase 1 data for ORKA-001, its IL-23p19 antibody. The trial demonstrated a half-life of approximately 100 days—three times longer than existing therapies like risankizumab—and a favorable safety profile with no severe adverse events. These results validate the drug’s potential for once-yearly dosing, a major differentiator in a market dominated by therapies requiring four to six annual injections. The data, presented at the EADV Congress, has repositioned ORKA-001 as a best-in-class candidate, while the $200 million follow-on offering signals management’s confidence in scaling the program.

Biotechnology Sector Rally: AMGN Leads as Oruka Surges
The broader biotechnology sector is in a bullish phase, with Amgen (AMGN) rising 0.7% as a sector bellwether. Oruka’s 10.6% move outpaces peers, reflecting its unique position in the psoriasis space. While AMGN’s growth is driven by its established oncology and immunology franchises, Oruka’s momentum stems from high-conviction clinical milestones and a capital-raising strategy that reduces near-term dilution risks. The sector’s 0.7% intraday gain underscores a risk-on environment, with investors favoring biotechs with clear catalysts like Oruka’s Phase 1 readout.

Options Playbook: Leveraging ORKA’s Volatility with Gamma-Driven Calls
• MACD: 2.35 (above signal line 1.57), RSI: 84.47 (overbought), Bollinger Bands: $25.86 (upper), $18.83 (middle), $11.80 (lower)
• 200D MA: $13.19 (far below current price), Kline Pattern: Short- and long-term bullish

Oruka’s technicals scream momentum. The RSI at 84.47 suggests overbought conditions, but the MACD histogram (0.78) and Kline’s bullish bias indicate a continuation trade. Key levels to watch: the 52W high of $31.13 and the 200D MA at $13.19 as a critical support. The stock’s 84.47 RSI and 10.6% intraday surge suggest a short-term overbought state, but the 100-day half-life data provides a strong narrative for a breakout above $30.

Top Options Picks:
• ORKA20251121C30 (Call, $30 strike, Nov 21 expiry):
- IV: 127.43% (high volatility)
- Delta: 0.5279 (moderate sensitivity)

- Turnover: $31,000 (liquid)
- Leverage Ratio: 7.05% (moderate)
- Price Change Ratio: 168.46% (strong momentum)
This call option is ideal for capitalizing on Oruka’s short-term volatility. The high IV and moderate delta balance risk and reward, while the Nov 21 expiry aligns with the EADV Congress and Phase 1 data visibility. A 5% upside to $29.62 would yield a payoff of $4.62 per contract, offering a 154% return on the $30 strike.

• ORKA20260220C30 (Call, $30 strike, Feb 20 expiry):
- IV: 107.47% (mid-range)
- Delta: 0.5974 (higher sensitivity)

- Gamma: 0.021397 (moderate)
- Turnover: $2,390 (liquid)
- Leverage Ratio: 4.27% (moderate)
- Price Change Ratio: 120.00% (strong)
This longer-dated call offers a safer play on Oruka’s 2026 milestones, including the Phase 2a trial readout. The 107.47% IV and 0.5974 delta make it responsive to price swings, while the Feb 20 expiry provides time for the stock to consolidate gains. A 5% upside would yield a $4.62 payoff, a 154% return on the $30 strike.

Action Alert: Aggressive bulls should prioritize ORKA20251121C30 for a short-term play on the EADV-driven momentum. Conservative investors may consider ORKA20260220C30 to hedge against near-term volatility while capturing long-term upside.
