NEW YORK The stock market has been mixed to modestly higher so far today, after world powers and Iran reached a deal on the country's nuclear program.
Stocks have seen seven weeks of gains.
Sunday's deal with Iran was the first significant progress in years to curtail that country's nuclear ambitions. It will reduce the risk of conflict, improve trade and could boost global oil supplies. The energy sector was the biggest decliner among the S&P 500's 10 industry groups.
Wal-Mart rose slightly after the company announced its CEO Mike Duke is stepping down.
