CSX on the move as Ackman chatter grows louder

• CSX jumped nearly 4% today on speculation that Bill Ackman has acquired a sizable stake in the railroad, and could reveal the stake Monday afternoon when he is scheduled to present at the Ira Sohn conference.
• Earlier this week, UBS analyst Thomas Wadewitz wrote that recent action in the stock suggests Ackman has been accumulating a position, and noted similar patterns observed with his stake in Canadian Pacific.
