Robert Pavlik, chief investment strategist and senior portfolio manager at SlateStone Wealth, says if the U.S. stock market is set up for selling pressure in 2020 the decline should be short-lived and investors should view the weakness as a buying opportunity. Pavlik says he expects the S&P 500 to rise seven to 10 per cent next year, and recommends an overweight position in tech, consumer discretionary, industrials and financials.
