(Reuters) -The S&P 500 benchmark U.S. stock index will end 2025 just below current near-record levels, reflecting tempered optimism amid ongoing concerns over the economic impact of President Donald Trump's global tariffs and uncertainty surrounding Federal Reserve rate cuts, according to a new Reuters poll. Market strategists polled by Reuters showed that concerns about potential stagnation related to tariffs have dampened optimism about Wall Street's rally in AI heavyweights. "I do not anticipate the United States entering a recession; however, I do expect the economy to experience a slowdown," said Robert Pavlik, senior portfolio manager at Dakota Wealth.
