Executive Summary
The same short-seller that smacked Valeant Pharmaceuticals International Inc. last month with a report exposing the firm's relationship with specialty pharmacies used only a tweet on Nov. 9 to whack its next victim, hedge-fund favorite Mallinckrodt PLC, whose shares plummeted 26%, before closing at $58.01, down $11.88, or 17% – demonstrating again the power of social media on stock prices.
