NEW YORK—Investors are weighing how big to go on U.S. technology stocks in the coming year, as pricier valuations, regulatory risks, and a revival of the market’s beaten-down names threaten to dim their allure.
A surge in technology and internet-related shares helped lift U.S. indexes to record highs this year. Gains in Apple, Amazon, and Microsoft alone accounted for more than half of the S&P 500’s 16.6 percent total return as of Dec. 16, according to Howard Silverblatt, senior index analyst at S&P Dow Jones Indices.
