• Q3 2025 revenue hits $27.4M, 30% YoY growth, with positive adjusted EBITDA of $0.1M for the first time.
• Full-year revenue guidance raised to $97–$98M, signaling 21–23% YoY growth despite Dixie product line wind-down.

NeuroPace’s intraday volatility reflects a seismic shift in market sentiment, driven by record revenue, margin expansion, and strategic clarity. The stock’s 37.9% surge—its highest since 2023—underscores investor optimism about the RNS system’s scalability and the Nautilus PMA submission timeline. With institutional buying and analyst upgrades amplifying momentum, the question now is whether this rally is a breakout or a flash crash.

Q3 Earnings Triumph and Strategic Optimism Fuel NeuroPace's Intraday Surge
NeuroPace’s 37.9% intraday surge stems from a trifecta of catalysts: record Q3 revenue of $27.4M (30% YoY), positive adjusted EBITDA of $0.1M, and a 77.4% gross margin—up from 73.2% in the prior year. Management’s guidance for $97–$98M full-year revenue (21–23% growth) and a 76–77% gross margin further solidified confidence. The stock’s rally coincided with Cantor Fitzgerald’s upgraded earnings estimates and a $60M cash balance, which eased concerns about the Dixie product line’s phase-out. Institutional buying, including 561,000 shares by Armistice Capital and 803,440 by Driehaus Capital, amplified the move. Analysts highlighted the RNS system’s 31% YoY growth and the Nautilus PMA submission timeline (Q4 2025) as key drivers of long-term optimism.

Healthcare Equipment Sector Mixed as NeuroPace Outperforms Medtronic
The broader Healthcare Equipment sector showed mixed momentum, with Medtronic (MDT) down 0.58% despite NeuroPace’s 37.9% surge. While Medtronic’s decline reflected sector-wide caution over regulatory risks and margin pressures, NeuroPace’s rally was fueled by earnings outperformance and strategic clarity. The stock’s 37.9% move far outpaced peers like Globus Medical (GMED), which is yet to report Q3 results. Analysts noted that NeuroPace’s focus on neuromodulation and AI-driven tools like Seizure ID positioned it uniquely within the sector, creating a divergence from traditional med-tech plays.

Options and ETF Playbook: Capitalizing on NeuroPace’s Volatility and Momentum
• RSI: 22.57 (oversold)
• MACD: -0.146 (bearish), Signal Line: 0.031, Histogram: -0.177
• Bollinger Bands: Upper $11.41, Middle $10.44, Lower $9.48
• 200D MA: $11.30 (above current price)
• Support/Resistance: 30D $9.40–$9.43, 200D $10.23–$10.42

NeuroPace’s technicals suggest a short-term overbought condition (RSI 22.57) and a bearish MACD, but the stock’s 37.9% surge has created a breakout above key resistance. Aggressive bulls should target the $13.81 intraday high as a potential continuation level, while bears may eye a retest of the $10.77 low. The options chain offers two high-leverage plays:

• NPCE20251121C12.5 (Call):
- Strike: $12.50, Expiry: 2025-11-21
- IV: 105.08% (high volatility)
- Delta: 0.609 (moderate sensitivity)
- Theta: -0.0488 (rapid time decay)
- Gamma: 0.1307 (high sensitivity to price moves)
- Turnover: 345 (liquid)
- Leverage: 9.25%
- Payoff at 5% upside ($13.61): $1.11/share. This call offers explosive potential if the stock holds above $12.50, leveraging high IV and gamma to amplify gains.

• NPCE20251219C12.5 (Call):
- Strike: $12.50, Expiry: 2025-12-19
- IV: 65.13% (moderate)
- Delta: 0.6145 (moderate sensitivity)
- Theta: -0.0185 (slow decay)
- Gamma: 0.1291 (high sensitivity)
- Turnover: 815 (liquid)
- Leverage: 9.06%
- Payoff at 5% upside ($13.61): $1.11/share. This longer-dated call balances time decay with liquidity, ideal for a mid-term bullish stance.

Action: Aggressive bulls should prioritize NPCE20251121C12.5 for a short-term breakout play, while NPCE20251219C12.5 suits a more measured approach. Both contracts capitalize on high gamma and IV to amplify returns if the stock sustains above $12.50.

Backtest NeuroPace Stock Performance
Hi, I tried to run an Event-backtest on NPCE’s ≥ 38 % one-day surges from 2022-present, but the back-testing engine threw an internal error (“convert_statistics not defined / min() arg is an empty sequence”). That means the platform couldn’t finish the calculation or generate the chart.Likely reasons 1. Only one surge at the 38 % threshold (the 37.98 % move on 2025-11-05) was found, so the engine’s statistics routine failed when it tried to take min/max on an empty array. 2. A bug in the engine’s post-processing code (“convert_statistics”) prevented completion even with a single date.Next steps – two optionsA. Quick manual workaround (no chart, but we can still calculate key numbers): • I can pull NPCE’s close prices for the event date (2025-11-05) and for, say, +1, +5, +10, +20 trading days and compute the simple after-event returns. • With only one event the results will just be those single-period figures (no aggregation), but they will answer “what happened after the ≥ 38 % surge?”.B. Retry with a lower surge threshold (e.g., ≥ 20 %) to capture a larger sample set. More events → engine will run without the single-event bug, and you’ll get the usual full analytics (average/median return curves, optimal holding window, win rate, etc.) plus an interactive chart.Please let me know which way you’d like to proceed (or provide another idea) and I’ll run the appropriate analysis.

NeuroPace’s 37.9% Surge: A High-Volatility Play with Clear Entry Points
NeuroPace’s 37.9% intraday surge reflects a rare confluence of earnings outperformance, strategic clarity, and institutional buying. While technicals suggest overbought conditions, the stock’s momentum—bolstered by a 77.4% gross margin and $60M cash balance—positions it for further gains if the $13.81 high holds. Investors should monitor the $12.50 level as a critical support/resistance threshold, with the November 12.5 calls offering the highest leverage. Meanwhile, the sector’s mixed performance, exemplified by Medtronic’s -0.58% decline, highlights NeuroPace’s unique positioning. Act now: Buy NPCE20251121C12.5 for a short-term breakout or NPCE20251219C12.5 for a mid-term bullish stance, targeting $13.61 as a 5% upside scenario.
