• Phase 2b REZOLVE-AA trial for alopecia areata shows 28.2% SALT score reduction in 24 µg/kg arm (p=0.186) but 29.6% after excluding four ineligible patients (p=0.049)
• Conference call today at 8:00 am ET to discuss results, with management and dermatology experts

Nektar Therapeutics faces a sharp intraday selloff following mixed Phase 2b trial data for rezpegaldesleukin in alopecia areata. Despite achieving statistical significance after excluding four ineligible patients, the market reacted to the initial primary endpoint miss. The stock traded between $45.25 and $49.00, reflecting heightened volatility and uncertainty ahead of the conference call.

Mixed Statistical Outcomes Spark Sell-Off
Nektar’s stock collapsed 8.44% as investors grappled with the dual narrative of the REZOLVE-AA trial. While the primary endpoint narrowly missed statistical significance (28.2% SALT reduction, p=0.186) in the 24 µg/kg arm, the exclusion of four ineligible patients retroactively validated the result (29.6%, p=0.049). This ambiguity triggered a risk-off reaction, with traders questioning the robustness of the data. The market’s focus on the initial miss overshadowed the positive safety profile and dose-dependent efficacy, which showed 30.3% reduction in the 18 µg/kg arm. The sell-off accelerated as the stock approached its 52-week low, reflecting skepticism about the FDA’s acceptance of adjusted data.

Options Playbook: Capitalizing on Volatility and Technical Breakdowns
• 200-day average: $27.43 (far below current price)
• RSI: 42.59 (oversold territory)
• MACD: -0.93 (bearish divergence)
• Bollinger Bands: $50.67 (lower band) vs. $65.23 (upper band)

Nektar’s technicals suggest a short-term bearish bias, with the 200-day MA acting as a critical support level. The RSI hovering near oversold territory implies potential for a rebound, but the MACD’s negative divergence and Bollinger Bands’ wide spread indicate prolonged volatility. For aggressive traders, the NKTR20251219P50 put option (strike $50, expiration 12/19) offers high leverage (18.89%) and a delta of -0.468, aligning with the stock’s downward trajectory. The NKTR20251219C50 call (delta 0.527) is a contrarian play, betting on a post-call bounce. Both contracts have high turnover ($109k and $10k, respectively), ensuring liquidity. Under a 5% downside scenario (target $46.36), the put’s payoff would be $3.64, while the call would expire worthless. Aggressive short-sellers may consider the put into a breakdown below $45.25, while bulls should watch for a retest of the $50.00 level.

Backtest Nektar Therapeutics Stock Performance
The performance of Nektar Therapeutics (NKTR) following a -8% intraday plunge from 2022 to the present can be summarized as follows:1. Earnings Performance: NKTR reported a quarterly loss of $0.79 per share in Q4 2022, which was slightly better than the consensus estimate of a loss of $0.81. This represents a deterioration from the previous quarter's loss of $0.65 per share. Despite this, the company has exceeded consensus EPS estimates four times over the last four quarters.2. Stock Price Movement: NKTR's stock has declined by approximately 26.1% since the beginning of 2022, which is a significant drop compared to the S&P 500's decline of -8% during the same period. This indicates that NKTR has underperformed the broader market.3. Investor Sentiment and Legal Issues: There is a sentiment of distrust among investors, as evidenced by the investigation into potential self-dealing by certain officers and directors. This could further impact investor confidence and stock performance.4. Future Outlook: The company's pipeline includes collaborations such as NKTR-358 with Eli Lilly for inflammatory diseases and NKTR-255 for cancer treatments, which could offer potential for future recovery. However, the sustainability of the stock's price movement will depend on management's commentary and the outcome of ongoing clinical trials.In conclusion, while there is some potential for recovery based on the pipeline and partnerships, the recent performance and investor sentiment suggest that NKTR's road to recovery may be challenging. Investors should closely monitor the company's developments and market conditions moving forward.

Act Now: Position for Post-Conference Call Volatility
Nektar’s sharp decline reflects market skepticism about the REZOLVE-AA data’s regulatory acceptance, but the stock’s proximity to its 52-week low and oversold RSI suggest a potential rebound. Investors should monitor the 12/16 conference call for clarity on the FDA’s stance and the 2026 Phase 3 plans. For now, the NKTR20251219P50 put offers a high-leverage bet on further downside, while the 200-day MA at $27.43 remains a critical long-term floor. Sector leader Amgen (AMGN) fell 0.27%, underscoring broader biotech caution. Watch for $45.25 support or a breakout above $50.00 to dictate next steps.
