It’s been about a year since President Trump took office Jan. 20, 2017. It’s sometimes been contentious and even chaotic. But, for investors, it’s been among the best of times.
The S&P 500 Index /zigman2/quotes/210599714/realtime SPX +1.06% of the largest U.S. stocks has returned 26.3% since Jan. 19, 2017, the day before Trump’s inauguration. This next year could be more of the same, helped by economic growth at home and abroad, low U.S. unemployment and the biggest federal tax cut in a generation.
“There’s still meat on the bone,” said Bill McMahon, chief investment officer at Charles Schwab unit ThomasPartners.
He said in an interview that Wall Street analysts have not yet fully incorporated the tax cuts Trump signed into law on Dec. 22 into their earnings estimates. That means those estimates will be rising, reducing stocks’ price-to-earnings ratios and, therefore, supporting more share-price gains.

Michael Cuggino is “overweight” stocks in his Permanent Portfolio /zigman2/quotes/205061618/realtime PRPFX -0.55% which is managed to take advantage of all sorts of market conditions. In an interview, he said growth in emerging economies means increased demand for commodities, which bodes well for the energy and materials sectors.
Cuggino said other sectors — banking, industrial technology, biotechnology, medical equipment and services, and transportation — are also getting a tailwind.
“Internationally focused U.S. businesses will do very well,” he said, as strengthening economies abroad have pushed down the value of the dollar, making U.S. exports more attractive.
Jim Brilliant, who manages the CM Advisors Fixed Income Fund /zigman2/quotes/206487783/realtime CMFIX -0.19% , said in an interview that simultaneous economic growth around the world will signal a “sector rotation” for stocks away from higher-growth industries into value plays in the industrial, energy and materials sectors.
