The "Fast Money" traders debated how to position their portfolios as the Dow Jones industrial average ticked higher on Tuesday.

Trader Pete Najarian said he's still watching the sectors that are continuing to push the market higher, like financials and technology, especially the semiconductors. He said that the valuations in the tech sector are "not stretched," even though the tech-heavy Nasdaq hit a fresh all-time high on Tuesday. Najarian argued that these stocks could actually help the Dow get over the 20,000 level.
