NEW YORK - US stocks ended higher on Monday as investors looked ahead to a potential resolution of the US federal government shutdown and awaited a wave of major corporate earnings reports.

The Dow Jones Industrial Average rose 515.97 points, or 1.12 percent, to 46,706.58. The S&P 500 gained 71.12 points, or 1.07 percent, to 6,735.13. The Nasdaq Composite advanced 310.57 points, or 1.37 percent, to 22,990.54.

Nine of the 11 primary S&P 500 sectors closed in positive territory, with communication services and materials leading the gainers, up 1.52 percent and 1.24 percent, respectively. Consumer staples and utilities were the only laggards, dipping 0.10 percent and 0.06 percent.

As the federal government shutdown nears the three-week mark, National Economic Council Director Kevin Hassett told CNBC on Monday that it is "likely to end sometime this week," adding that "moderate" Democrats could help reach a deal. He also said the White House was prepared to take stronger measures if an agreement is not reached soon.

Apple shares climbed 3.94 percent to a record close after Loop Capital upgraded the stock to "buy" from "hold," citing strengthening iPhone demand and forecasting sustained shipment growth through 2027. Moreover, Apple's five-year contract with F1 for exclusive streaming rights could mean short-term pain but would lead to long-term gains, according to Morgan Stanley.

Following the first week of the third-quarter earnings season, 76 percent of the 58 S&P 500 companies that have reported results so far have beaten earnings expectations, which is well above the first-week average of 68 percent and slightly higher than last quarter's 73 percent, according to Bank of America.

Major companies, including Netflix, Coca-Cola, Tesla and Intel are set to report results this week, with investors hoping strong corporate earnings will continue to offset broader macroeconomic uncertainties.

With all the spending on AI and the market's rally this year, Canaccord Genuity said the pressure is on for Big Tech companies heading into earnings. "With this much market value added in such a short amount of time, the bar may be high for tech bellwether earnings reports this quarter," analyst Michael Graham wrote to clients in a Monday note.
