NEW YORK (MarketWatch) -- U.S. stocks on Monday built on last week's advance, helped by deal news and waning Ukraine-Russia tensions.

A better-than-expected reading on the housing market also boosted sentiment and kicked off a big week for economic data.

The S&P 500 (SPX) rose 14 points, or 0.7%, to 1,969, adding to its 1.2% weekly gain last week. The Dow Jones Industrial Average(DJI) jumped 163 points, or 1%, to 16,826, while the Nasdaq Composite (RIXF) climbed 38 points, or 0.9%, to 4,503.

The tech-heavy Nasdaq traded as high as 4,509.16 -- a new intraday high for the year and a level last seen in March 2000. Yahoo Inc.(YHOO) and Google Inc.(GOOGL) (GOOG) rose 2.4% and 1.9%, respectively, as tech stocks enjoyed broad gains.

"The political concerns that whipped markets around on Friday subsided over the weekend with Ukraine and Russia apparently talking and making some progress," said Colin Cieszynski, chief market strategist at CMC Markets, in a note. He also emphasized encouraging news from Iraq, noting that "Kurdish forces regained control of the key Mosul Dam from ISIS."

Alastair McCaig, market analyst at IG, pointed out the Dow might regain a big round number.

"Wall Street is once again coming up to tackle technical resistance, but with the momentum built up over the last week, conversations are likely to turn towards when, not if, it can tackle the 17,000 level again," McCaig said in a note.

Helping out, he said, was the bounce off session lows seen Friday, when the Dow recovered from a triple-digit fall. Also read: Where Soros and other big investors are putting their money right now

Foreign ministers from Ukraine and Russia met over the weekend, and an agreement was reached over a convoy of what Russia says is humanitarian aid. However, no progress was made toward a cease-fire in Eastern Ukraine. The news pushed the Europe Stoxx 600 to its highest close so far this month.

On the economic front, the National Association of Home Builders/Wells Fargo Housing Market Index for August came in at 55, its highest level in seven months. Economists polled by MarketWatch had expected a reading of 53. Stocks strengthened further after the housing report.

This week also should bring data on housing starts and consumer prices on Tuesday, as well as minutes from the last Federal Open Market Committee meeting on Wednesday.

Federal Reserve Chairwoman Janet Yellen will give a speech Friday at the annual Fed summit in Jackson Hole, Wyo. Yellen is expected to say there's still slack in the job market, and she isn't likely to shift the Fed's easy-money stance, said Jan Hatzius, chief economist at Goldman Sachs, in an interview with MarketWatch.

Dollar General makes play for Family Dollar

Shares of Dollar General Corp.(DG) rose 11%, faring best in the S&P 500, after offering to buy rival Family Dollar Stores Inc. (FDO) in an all-cash deal worth $78.50 a share. That's higher than Dollar Tree Inc.'s (DLTR) cash-and-stock bid in July of $74.50 a share. Family Dollar jumped 5% for the second-best gain in the S&P 500.
