U.S. stock futures surged Friday after China's central bank cut interest rates and the European Central Bank's president reiterated that the institution was ready to expand its stimulus program.

Dow Jones Industrial Average futures jumped 134 points, or 0.8%, to 17829. S&P 500 futures advanced 16 points, or 0.8%, to 2068 and Nasdaq-100 futures gained 32 points, or 0.8%, to 4277. Changes in stock futures don't always accurately predict moves in the stock market after the opening bell.

Futures were bolstered by indications that stimulus actions by global central banks will continue to support stock gains. European shares also rallied.

China's central bank cut lending rates for the first time in more than two years, a surprise move that ramped up its efforts to bolster flagging growth. China has an annual growth target of about 7.5%, and expectations are building that it could miss that target. The People's Bank of China on Friday cut its benchmark one-year loan rate by 0.4 percentage point to 5.6%, the first cut since July 2012.

European Central Bank President Mario Draghi said the central bank was ready to fight dangerously low inflation by expanding its asset-purchase programs. The Stoxx Europe 600 jumped 1.6% while the euro dropped to $1.2435.

"The combination of Chinese and European stimulus has certainly put a bid in European markets and appears to be doing the same here," said Art Hogan, chief market strategist at brokerage firm Wunderlich Securities.

U.S. stock-market gains in recent years have been credited with the Federal Reserve's unprecedented stimulus, creating a supportive environment for financial assets such as stocks. While the Fed has ended its bond-purchase program and is considering an interest-rate increase, other central banks are expanding stimulus efforts as they battle slowing growth. The Bank of Japan last month unexpectedly added to its stimulus measures, prompting a rally in global stocks.

On Thursday, the Dow industrials and S&P 500 closed at records, boosted by a rise in oil prices. The news of Chinese stimulus suggested that Chinese demand for crude oil could increase, further boosting prices, said Mr. Hogan. Crude-oil futures surged 2.3% to $77.62 a barrel.

"That's a good sign because one of the...drags on the market has been the pullback in energy prices," he said.

Gold futures rose 0.8% to $1200.60 an ounce. The yield on the 10-year Treasury note inched up to 2.343% from 2.335% on Thursday.

In corporate news, Valeant Pharmaceuticals Inc. is launching a $2 billion securities buyback program, which will begin Friday. The company recently lost its bid to buy Allergan Inc.

Ross Stores Inc. shares rose 6.7%. The discount retailer's third-quarter profit rose, with per-share earnings beating its own projections. Same-store sales rose 4%, also topping the company's forecast.
