Wendy's shares have rallied by 15 percent as Nelson Peltz's Trian group has put forth to buy the burger chain for $1.4 billion. This offer comes at a time when Wendy's is dealing with challenges such as rising beef expenses and growing competition. A confrontation at a Wendy's restaurant in Los Angeles, involving a man with a knife and another with a grin, has spread widely. The incident occurred in Northridge and the man involved has addressed the event. The buyout offer reflects investors' trust in Wendy's amidst these challenges.
