CBS' net income of 88 cents per share beat analysts' expectations, but revenue disappointed as advertising sales fell 4 percent.
"I think the revenue miss weighs heavier than the earnings beat. I wouldn't jump in right here," said trader Karen Finerman.
CBS shares rose about 2 percent in extended trading after the results. The stock "has been an underperformer" since last year and looks cheap compared to some peers, added trader Guy Adami.
One of those competitors, Walt Disney, sent concerns through the television sector when CEO Bob Iger warned on the health of the cable business earlier this year. When the company reports earnings Thursday, it will likely avoid similar disappointment, Adami said.
"I think you're going to see a surprise to the upside in Disney," he said.
Disney shares have climbed 22 percent this year. With "very positive sentiment" ahead of the results, investors should consider cutting their stake, contended trader Brian Kelly.
