MARKET SNAPSHOT: Stock Market Books Weekly Loss As'life-threatening' Hurricane Irma Aims For Florida

Fears of potential North Korean missile launch spook investors, too

U.S. stock indexes closed mostly lower Friday, finishing a holiday-shortened week with modest losses, as investors traded cautiously ahead of a potential missile test by North Korea and Hurricane Irma's arrival on the Florida coast over the weekend.

The S&P 500 index closed 3.67 points, or 0.2%, lower at 2,461.43, ending an up-and-down week with a 0.6% loss.

Stock indexes perked up briefly in the morning after news that the House of Representatives passed legislation extending the U.S. debt limit (http://www.marketwatch.com/story/house-passes-hurricane-aid-plus-extension-of-debt-limit-and-government-funding-2017-09-08-10914110) and government funding through Dec. 8. The bill, already approved by the Senate, now goes to President Donald Trump for his signature.

"Nobody really believed that we would have a debt ceiling problem, but certainty that it's not going to be a problem is worth a couple of ticks higher," said Steve Chiavarone, portfolio manager at Federated Global Allocation Fund.

Chiavarone said in the absence of earnings news until October, there is a potential for a small pullback.

"We've reduced our overweight allocation to stocks in the short term as we think the S&P 500 could drop to 2,380-2,400 levels," Chiavarone said.

The Dow Jones Industrial Average eked out a small gain, adding 13.01 points, or less than 0.1%, to 21,797.79, but ended the week 0.9% lower. Insurance giant Travelers Co., Inc.(TRV) led the gains, up 4%.

The Nasdaq Composite Index declined 37.68 points, or 0.6%, to 6,360.19 and ended the week with a 1.2% loss.

"It's no surprise to see a waning of risk appetite into a weekend that looks likely to see another hurricane hit the U.S.," said Mike van Dulken, analyst at Accendo Markets. "Especially with the continued geopolitical threat from North Korea and after overnight trade data from China (http://www.marketwatch.com/story/china-exports-up-but-strong-yuan-a-drag-2017-09-08) was rather mixed, begging questions about global growth."

The dollar continued its descent Friday, with the ICE Dollar Index falling 0.4% to 91.329, its worst week since May (http://www.marketwatch.com/story/dollar-facing-worst-week-since-may-hit-by-geopolitical-tensions-and-falling-yields-2017-09-08). U.S. yields also fell over the week, with the yield on 10-year Treasurys settling at 2.06%.

The period's weakness comes as investors have grappled with the increasing geopolitical threat from North Korea and powerful Atlantic storms barreling toward the U.S.

North Korea last weekend tested its biggest nuclear bomb to date, and the regime is feared to be preparing a missile launch (http://www.marketwatch.com/story/north-korea-is-getting-ready-for-another-possible-icbm-launch-says-south-korea-2017-09-04) on Saturday to mark the celebration of its founding day.

Closer to home, traders have monitored the path of Hurricane Irma, which is gradually moving closer to south Florida (http://www.marketwatch.com/story/hurricane-irma-downgraded-to-category-4-but-remains-extremely-dangerous-on-its-path-to-florida-2017-09-08) and is expected to make landfall late Saturday or early Sunday. The storm system has already wreaked havoc on a string of Caribbean islands, leaving at least 13 people dead and buildings on two small islands--Barbuda and St. Martin--almost completely destroyed.

The National Hurricane Center warned (http://www.nhc.noaa.gov/news/AL112017_key_messages.png?036) that Irma's expected Florida landfall will be a "life-threatening situation" and advised residents to follow evacuation orders from officials.

As devastating as the hurricanes are, they are likely boost the economy, according to New York Federal Reserve Bank President William Dudley. (http://www.marketwatch.com/story/feds-dudley-says-hurricanes-harvey-irma-to-give-unfortunate-boost-to-us-economy-2017-09-08)

"The long-run effect of these disasters, unfortunately, is it actually lifts economic activity because you have to rebuild all the things that have been damaged by the storms," Dudley said in an interview with CNBC (https://www.cnbc.com/2017/09/08/feds-dudley-hurricanes-will-boost-economic-activity-over-the-long-run.html).

Despite hurricanes, shares of insurance companies were higher (http://www.marketwatch.com/story/insurers-brace-for-a-1-in-100-year-storm-as-irma-bears-down-on-florida-2017-09-08) on Friday, though reinsurers suffered big falls since Harvey hit Texas. Among big insurers, shares of Everest Re Group Ltd.(RE) rose 5%, but was still down 10% over the week. XL Group Ltd.(XL) rallied 5.8%, trimming its weekly decline to 5%.

Shares of American International Group(AIG) and Allstate Corp(ALL) also advanced, up 2.6% and 3.7% respectively.

Shares of Target Corp.(TGT) and other retailers fell sharply after the company said on its website that it had "lowered prices on thousands of items (http://www.marketwatch.com/story/targets-price-cuts-on-thousands-of-items-sinks-retailer-stocks-2017-09-08)," fueling concerns over a price war amid a lackluster sales environment.

Other markets: Stocks across Asia closed mostly lower (http://www.marketwatch.com/story/asian-markets-waver-after-yen-peaks-at-10-month-high-2017-09-07) as the fallout from Hurricane Irma and North Korea tensions weighed on investors' minds. European stocks (http://www.marketwatch.com/story/european-stocks-fall-as-missile-threat-hurricanes-unsettle-investors-2017-09-08)ended a choppy day slightly higher.

Crude-oil prices (http://www.marketwatch.com/story/us-oil-prices-slide-in-harveys-wake-but-brent-rises-2017-09-08) dropped more than 3%, settling at the lowest level in a week in the wake of Hurricane Harvey and slow recovery of refineries. Meanwhile, gold prices (http://www.marketwatch.com/story/gold-trades-at-highest-in-a-year-boosted-by-bruised-dollar-and-sinking-treasury-yields-2017-09-08) notched a third weekly gain in a row, settling at their highest level in a year.
