We’re a month into President Trump's second term and there’s 47 more to go, which means investors need to make peace with a less predictable market backdrop and get on with it. While sitting on the sidelines for the next four years is one strategy, it’s unlikely to be a very good one. Don't forget, the S&P 500 increased 58 per cent during Trump’s first term despite plenty of twists and turns, and there’s every chance you’ll be rewarded for keeping your cool this time around too.
