On Monday's edition of Final Trades, the "Halftime Report" traders focused in on two sectors that have outperformed this year -- tech and health care. The former is up more than 37% year-to-date while the latter is up more than 20%.
Twitter is up more than 30% this year despite facing heavy competition from big tech companies like Facebook and Alphabet, and traders Josh Brown and Joe Terranova see no signs of it slowing down.
"You've got to pay attention to what is going on in Twitter shares," said Terranova. "A lot of strong momentum has come into it here, clearly, in the last six weeks. It looks like it wants to break out."
Twitter shareholder Josh Brown is also bullish on the stock, noting that the social media giant is "under owned" given its surge higher over the last year.
Steve Weiss, on the other hand, doesn't attribute Twitter's move higher to anything "company specific." He points out that Snap has risen almost 30% in the past month.
Instead, Weiss is watching biotech ahead of several key industry conferences in January. Specifically on his radar is Celgene. The stock is down almost 7% this year but positive results from a blood cancer study did push the stock higher during Monday's trading session.
Jim Lebenthal also tapped into healthcare, making a bullish call on Pfizer pharmaceuticals. He believes the the stock is "looking to break out."
