NEW YORK (MarketWatch) -- U.S. stock futures climbed on Thursday, lifted by better-than-expected quarterly results and upbeat eurozone data.

Weekly jobless claims rose last week, but remained below the key 300,000 level for the sixth straight week, reflecting the low level of layoffs taking place in the economy.

Better-than-expected quarterly results from Caterpillar Inc., 3M were bolstering futures for the Dow Jones Industrial Average (DJZ4), which jumped 134 points, or 0.8%, to 16,560.

Investors await updates on the U.S. manufacturing sector later this morning.

Futures for the S&P 500 (SPZ4) gained 14 points, or 0.8%, to 1,939. Futures for the Nasdaq-100 (NDZ4) jumped 30 points, or 0.8%, to 3,980.

Dow futures before the deluge of corporate results surged by more than 100 points after data firm Markit said the initial October reading of its eurozone manufacturing purchasing managers index reached a two-month high at 50.7, above expectations of a reading at 50. The report offered some upbeat news at a time when worries about slowing global economic growth have prompted investors to sell off equities world-wide.

But the report also suggested manufacturers and service providers don't expect a significant pickup in the pace of activity in the coming months.

U.S. stocks on Wednesday finished lower, with the S&P 500 index (SPX) losing 0.7%, the Dow Jones Industrial Average (DJI) down 0.9% and the Nasdaq Composite (RIXF) off 0.8%.

Data: The number of people who applied for U.S. unemployment benefits rose by 17,000 last week to 283,000. Economists polled by MarketWatch had expected claims to rise to a seasonally-adjusted 285,000 in the week ended Oct. 18. Markit will release its initial October purchasing manufacturing index for the U.S. at 9:45 a.m. Eastern Time.

The Federal Housing Finance Agency was slated to post a report on home prices for August at 9:00 a.m., and the Conference Board's leading indicators data are set for release at 10 a.m. Eastern.

Shares in Tractor Supply Co (TSCO) surged 11%, after it was raised to strong buy from market-perform by Raymond James .

Earnings: Ahead of the opening bell, shares of Dow industrials component Caterpillar (CAT) leapt 3.7%. The heavy-equipment maker raised its earnings outlook for the year to $6.50 a share, from $6.20, while keeping the midpoint of its revenue view unchanged. Third-quarter adjusted earnings of $1.72 a share outstripped expectations of $1.36 a share.

3M (MMM), another component of the Dow Jones Industrial Average, said third-quarter earnings were $1.98 a share, above expectations of $1.96 a share from a FactSet survey of analysts. Sales of $8.1 billion, however, were shy of Wall Street's estimate of $8.227 billion. Shares of the maker of Post-it notes and other industrial goods rose 2.5%.

General Motors (GM.XX) posted earnings, excluding one-time costs, of 97 cents a share, higher than projections of 95 cents a share. GM rose 2.7%.

Cable company Comcast Corp. (CMCSA) said third-quarter profit climbed 50%, benefitting from a one-time income-tax adjustment and a boost in earnings at its NBCUniversal entertainment unit. Shares rose 1.9% premarket.

Drug maker Eli Lilly & Co. (LLY) shares fell 1% after it reported a 58% drop in third-quarter earnings and a 16% fall in revenue, driven by patent expirations and competition from generic medications.

Southwest Airlines Co. (LUV) reported third-quarter adjusted earnings of 55 cents a share, more than Wall Street's estimate of 53 cents a share. Shares gained 2.9% in premarket trade. Southwest stock gained more than 80% since the start of the year.

Under Armour (UA), which makes athletic apparel, reported third-quarter profit and sales above expectations, but shares fell 5% in premarket trade after surging 51% so far this year.

Elsewhere premarket, shares of Yelp (YELP) dropped 12%. The online review site late Wednesday posted better-than-expected third-quarter results but issued a weak outlook.

After the bell, Amazon.com Inc. (AMZN) and Microsoft Corp. (MSFT) will release financial reports.

Other markets: In Asia overnight, stocks in Tokyo and Hong Kong finished modestly lower. European stocks were higher in a choppy trade. Gold futures (GCZ4) fell and oil prices (CLZ4) edged up.
