Morning Money Memo…

All signs are green for stock averages today after seven straight weeks of gains. While Congress may be deeply skeptical about the temporary uranium enrichment deal reached by the US and other world powers with Iran, the initial reaction from financial markets is positive. Iran has the world's fourth-largest oil reserves, but its exports have been sharply reduced by sanctions.

France's foreign minister says sanctions against Iran could be partially lifted as soon as December.

It's the start of a holiday-shortened trading week and investors are fired up. The S&P 500 index closed above 1,800 for the first time on Friday. The Dow also continued its upward march after finishing above 16,000 for the first time Thursday. Stock market averages are on track to post their strongest annual gains in 15 years. The Dow Jones industrials have gained 25 percent since Jan. 1.

The holiday shopping season has arrived and retailers are nervous. Millions of consumers will be out in force on Black Friday. Walmart, Target, Toys R Us and some other big retailers plan to launch their big sales early, opening on Thanksgiving Day. Back-to-school sales numbers were tepid in August, while consumer confidence has fallen since the summer. Both trends have led to gloomy holiday shopping forecasts.

"What we found in the past is that many of these deals will eventually be offered online either from the same store or from a competitor," says Lindsay Sakraida of Dealnews.com. "It's really not necessary to go unless you want something very specific."

Boeing is soliciting bids from more than a dozen sites that want to build the new 777X airplane and add thousands of jobs. Boeing says it hopes to make a final decision early next year.

The statement is the latest advisory on the 787 that was grounded earlier this year.
