Trader Radar - Monday January 5th

Q: On Fast Money’s trader radar we look at the stock that was lighting up screens across Wall Street. Founded 35 years ago, this weight loss company started off by selling a liquid protein diet. These days, with the help of celebrity endorsers like Marie Osmond and Dan Marino, the company advertises its direct-mail meal programs. Today, the company, while looking to shrink the size of its customers, bulked up on distribution, after agreeing to sell its products at Costco. Who is it?

A: On the trader radar tonight we’re watching NutriSystem ! The weight management program was among the most active names on the Nasdaq today.
