(AP) -- Stocks were moving higher on Wall Street Monday as investors held out new hope for progress in U.S.-China trade frictions. Health care companies, retailers and technology stocks drove the gains as the market overcame a midmorning wobble. The benchmark S&P 500 index was on track to end a volatile year with its worst showing in a decade.
KEEPING SCORE: The S&P 500 index rose 10 points, or 0.4 percent, to 2,496 as of 2:06 p.m. Eastern Time. The Dow Jones Industrial Average gained 169 points, or 0.7 percent, to 23,231. The Nasdaq added 24 points, or 0.4 percent, to 6,608. The Russell 2000 index of smaller-company stocks picked up 2 points, or 0.2 percent, 1,339.
Trading has been highly volatile in December, capping a year of turbulence for markets. The major indexes closed last week with their first weekly gain in what's been an otherwise painful month. The indexes are still all down around 10 percent for the month and are on track for their worst December since 1931.
THE QUOTE: "Last week we really had such a volatile week, and a lot of that had to do with thin trading volumes, some computerized trading and investors just being exhausted from a very difficult fourth quarter," said Jeff Kravetz, regional investment strategist at U.S. Bank Wealth Management. "Today is the last day of the year and investors are starting to look into next year."
US-CHINA TRADE: Investors drew encouragement from a tweet from President Donald Trump on Sunday, in which the president said he had a "long and very good call" with Chinese President Xi Jinping. Trump added: "Deal is moving along very well. If made, it will be very comprehensive, covering all subjects, areas and points of dispute. Big progress being made." Meanwhile, the official Xinhua News Agency cited a Chinese Foreign Ministry spokesman as saying that "China stands ready to work with the United States to move forward the China-U.S. ties which are underpinned by coordination, cooperation and stability."
Stocks also got a boost in early December when the U.S. and China agreed to a truce on trade, but then plunged when it was unclear what exactly both sides had agreed upon.
LOUSY YEAR: The S&P 500 index, the market's main benchmark, is on track for a loss of 6.5 percent this year, or 5.2 percent once dividends are included. The last time the index fell for the year on that basis was in 2008 during the financial crisis, when it lost 37 percent. The S&P 500 posted tiny losses in 2011 and 2015, but eked out small gains in both years once dividends were included.
THAT HEALTHY FEELING: Health care stocks were among the biggest gainers. Regeneron Pharmaceuticals rose 2.3 percent to $370.99.
TECH RALLY: Big-name technology companies, a big driver of the market's gains before things deteriorated in October, also rose. Advanced Micro Devices picked up 2.4 percent to $18.25.
READY TO SHOP: Traders bid up shares in department store chains and other retailers. Best Buy gained 2 percent to $52.39. Amazon rose 1.7 percent to $1,503.26.
WEAK SIGNALS: Shares in internet service providers and media companies slumped. DISH Network lost 2.8 percent to $24.26. Facebook slid 2.2 percent to $130.26.

Cabot Oil & Gas dropped 3 percent to $22.26.

CURRENCIES: The dollar fell to 109.69 yen from 110.41 yen on Friday. The euro strengthened to $1.1445 from $1.1442.

Germany's DAX, which was closed Monday, has been one of the worst-performing European indexes.
