Today kicks off the busiest week in earnings season.

The "Halftime Report" traders gave a preview of what to expect.

Pete Najarian thinks 3M will outperform given the numbers other industrial companies have reported.

When it comes to Eli Lilly, Steve Weiss is looking for guidance on pricing pressure and the election.

Joe Terranova remains bearish on Twitter, saying "I still don't see the strategy looking forward."

Large cap pharmaceutical companies have been on the up, noted Jim Lebenthal, so he's expecting Bristol-Myers to outperform.

The desk is split on biotech--Pete Najarian is weary of the sector, believing that we might see more pain ahead with the upcoming election. Steve Weiss, on the other hand, thinks earnings will surpass expectations due to money from the tech sector flowing into biotech.
