Notable Friday Option Activity: CSCO, SLNO, MDB

Soleno Therapeutics (SLNO) and MongoDB (MDB) are experiencing unusually high options trading volume today, with SLNO's 8,413 contracts representing 70.2% of its average daily share volume and MDB's 16,634 contracts representing 69.3%. Notably, significant activity is concentrated in specific long-dated put options: the $50 strike for SLNO expiring January 2026 (2,002 contracts) and the $202.50 strike for MDB expiring August 2025 (1,361 contracts). This elevated options activity, particularly in out-of-the-money puts, suggests an increase in bearish positioning or hedging strategies in these names.

Key Decisions for Investors

• Investors should monitor these specific long-dated put strikes for continued volume, as persistent activity could signal institutional hedging or a sustained bearish outlook on SLNO and MDB.
• Given the substantial size of these trades relative to daily volume, holders of these stocks may consider reviewing their own risk management and hedging strategies against potential future price declines.
• The unusual options activity warrants further investigation into potential, unstated fundamental drivers, such as upcoming sector-specific headwinds or company-specific events that could motivate such large, protective trades.
