NEW YORK — Investors were looking for any reason to look past the cold weather that has hampered the U.S. economy in the last few weeks, and they found it.
Stocks mostly rose Thursday, lifted by a report that showed the number of people who filed for unemployment benefits fell last week to the lowest level in three months. The gains were enough to give the Standard &Poor’s 500 index its third all-time high this week.
The report on unemployment claims was one of the first bits of good news investors have gotten on the economy after weeks of data that showed the U.S. recovery temporarily slowing because of the severe winter.
“Investors are putting more weight on the data that makes sense and ignoring the data that was impacted by the harsh winter weather,” said Kate Warne, a market strategist with Edward Jones.
The S&P 500 index rose 3.22 points, or 0.2 percent, to 1,877.03.
Staples fell the most of any stock in the index after the office supply chain said it would close 10 percent of its stores. Nearly half of its sales are now generated online. The stock fell $2.05, or 15 percent, to $11.35.
Staples is the second major brick-and-mortar retailer this week to announce widespread closures. Two days ago, RadioShack said it would close as many as 1,100 locations as part of a restructuring effort.
The Dow Jones industrial average rose 61.71 points, or 0.4 percent, to 16,421.89. The Nasdaq composite fell 5.85 points, or 0.1 percent, to 4,352.13.
The number of people who filed for unemployment benefits fell by 26,000 last week to 323,000, according to the Labor Department. That was far less than the 337,000 claims economists had expected, according to FactSet, and a sign that fewer people are being laid off.
Typically investors would not put much weight in the weekly unemployment report because the numbers can be volatile. But with the rest of the data they have at their disposal tainted by the weather, including Friday’s closely watched government jobs report, investors don’t have much to work with at the moment. The winter storms died down last week, so this data is the first “clean” reading on the economy.
The figures for weekly unemployment claims coming up over the next several weeks will be the freshest data investors will have, strategists said.
