Still in a loss-making state (EPS: -$5.33)	Sufficient cash reserves, operations secured through 2028
Selling occurred during the window for key data release	Key data for ALK-positive NSCLC to be released soon

For biopharmaceutical companies, the signal significance of insider selling needs to be

:

Scenario	Signal Strength	Explanation
Selling + Pipeline Clinical Failure	Strong Bearish	Insider information confirms a pessimistic outlook
Selling + Post-Financing Plan Execution	Neutral-Bearish	Likely a routine disposal
Selling + Strong Fundamentals + Institutional Buying	Mildly Bearish	Requires comprehensive judgment based on scale and timing

: Falls into the third category, where the signal significance of insider selling is partially offset by the company’s strong fundamentals.

• Maintain a Cautious Stance
  : The sideways trading pattern remains unbroken, but collective insider selling and the slightly bearish MACD signal indicate insufficient short-term upward momentum
• Key Catalyst
  : Focus on the release of key data for ALK-positive NSCLC by the end of 2025 (guidance from Q3 2025 earnings report on October 30, 2025) [0]

• Accumulate on Dips
  : Consider initiating positions if the stock price falls below $100
• Target Price Reference
  : $132.00 (consensus target price) [0]

• Due to Beta=1.32, it is recommended to
  limit biotech exposure to within 5% of the portfolio
• Set stop-loss levels in the
  $95-98 range
  (close to the 50-day moving average)

:

1. Signal Strength
   : Moderately Bearish (⭐⭐☆☆☆)
   • The selling behavior conveys a partial conservative outlook from executives on short-term stock performance
   • However, the selling scale is relatively limited, and it occurred during the routine disposal window after the public equity offering

2. Divergence from Fundamentals
   : A certain degree of divergence exists
   • 100% Buy rating from 13 professional analysts vs. collective executive selling
   • Investors are advised to focus more on fundamental factors such as the company’s
     clinical progress
     and
     regulatory approvals

3. Final Judgment
   : The insider selling signal
   does not constitute a sell recommendation
   , but should be included as a
   risk warning
   in investment decision-making. In the biopharmaceutical sector, the interpretation of insider trading requires comprehensive consideration of pipeline progress, financing cycles, and industry environment, and should not be blindly followed.
