The brief
Onsemi’s agreement to acquire Synaptics for approximately $6.2 billion in stock sets the episode’s central market event and raises the question of how investors price the deal.
Ellie Lipschultz explains the merger’s stock movements and the arbitrage trade, while the report highlights veteran technology M&A banker Frank Quattrone’s involvement.
The focus widens from one transaction to semiconductor-sector volatility, with SanDisk falling as the Philadelphia Semiconductor Index reacts to recent Micron earnings.
Acadia Pharmaceuticals provides a contrasting market move: its shares jumped after a positive European regulatory opinion for its Rett syndrome drug.
Taken together, the episode shows how deal mechanics, earnings-driven sector sentiment, and regulatory news can pull stocks in sharply different directions.
