Earnings reporting season for Q4 2018 results is off and running this week.

The major financial institutions are first out of the gate.

Over the past decade, the composite S&P Financials Sector has been the worst-performing of the major market sectors, straight through from the beginning to the end of fourth quarter earnings season.

Defensive sectors like Healthcare and Consumer Staples are top-performers at the beginning of the season.

But it's the Information Technology Sector that ultimately ends up as the Q4 season winner, by a healthy margin.
