Stocks rose and oil prices fell Tuesday as the risk that the U.S. would attack Syria appeared to fade.
The Standard & Poor’s 500 index had its sixth straight gain, the longest winning streak since July.
Stocks set new highs in early August, but worries over Syria have pushed them lower since then. Even though Syria isn’t a big oil producer, the possibility of a wider conflict in the region drove oil prices to two-year highs last week.
On Tuesday, investors were relieved that Syria accepted a proposal to put its chemical weapons under international control for dismantling. The possibility that the crisis between the U.S. and Syria might be solved peacefully was a factor in the stock market’s gain on Monday, too.
The Dow Jones industrial average rose 127.94 points, or 0.9 percent, to close 15,191.06. The Standard & Poor’s 500 index rose 12.28 points, or 0.73 percent, to 1,683.99 and the Nasdaq composite rose 22.84 points, or 0.62 percent, to 3,729.02.
Crude oil, which closed above $110 a barrel on Friday, lost $2.13, almost 2 percent, to close at $107.39 a barrel.
All 10 industry groups in the S&P 500 rose. The biggest gains were in financial and industrial stocks.
The Dow average got a shakeup on Tuesday. It’s dropping Bank of America, Hewlett-Packard and Alcoa, to be replaced by Goldman Sachs, Nike, and Visa at the start of trading on Sept. 23. The Dow is made up of 30 stocks.
S&P Dow Jones Indices said the change won’t disrupt the level of the industrial average. It said it made the change to diversify the sector and industry group representation of the index.
Hewlett-Packard fell 9 cents, or 0.4 percent, to $22.27. Alcoa was roughly flat and Bank of America rose 13 cents, or almost 1 percent, to $14.61.
Visa rose $6.04, or 3.4 percent, to $184.50; Nike rose $1.42, or 2.2 percent, to $66.82, and Goldman Sachs rose $5.65, or 3.5 percent, to $165.14.
