* U.S. stocks rise on bargain hunting, Google
* Yen gains broadly as risk appetite fades
* Oil rises on expectations OPEC to cut supplies (Recasts with close of European markets, U.S. stocks higher, freshens pricings)
By Herbert Lash
NEW YORK, Oct 17 (Reuters) - U.S. and European stocks rose sharply on Friday, as energy shares rose on higher oil prices on expectations that OPEC could cut output next week.
Reassuring results from Web search leader Google <GOOG.O> and IBM <IBM.N> buoyed the U.S. technology sector, driving the Dow industrials above 9,000.
But fears of recession still gripped some markets as reports showed U.S. consumer sentiment suffered its steepest monthly drop on record in October and housing construction starts fell to a 17-1/2-year low last month, driving the dollar down against the yen in choppy trade.
A safe-haven bid for Treasuries, however, was curbed as U.S. stocks turned higher.
Crude prices jumped 5 percent, drawing support from rising expectations of a supply cut by the Organization of Petroleum Exporting Countries after the oil cartel brought an emergency meeting forward to next week.
U.S. light sweet crude oil <CLc1> rose $3.51 to $73.36 a barrel.
Spot gold prices <XAU=> fell $14.50 to $790 an ounce.
Bargain hunters were encouraged by famed investor Warren Buffett who wrote in The New York Times that with fear high in the minds of many investors, it was time to buy U.S. stocks.
In Europe shares gained 4.2 percent, ending a volatile week on a strong note thanks to energy stocks that tracked a recovery in crude, while drugmakers rose ahead of key company reports next week.
"What helps is that we've ended the week in the same way it started, on an upbeat note," said Mike Lenhoff, chief strategist at Brewin Dolphin.
"I somehow felt that although this week was marked by just as much volatility as last week, it had a different feel. There was encouragement from the steps the governments have been taking (to deal with the banking crisis)," Lenhoff said.
The pan-European FTSEurofirst 300 finished the week 6.3 percent higher.
In U.S. markets, bargain hunting for beaten-down shares also bolstered shares.
The Dow Jones industrial average <
> was up 183.98 points, or 2.05 percent, at 9,163.24. The Standard & Poor's 500 Index <.SPX> was up 23.06 points, or 2.44 percent, at 969.49. The Nasdaq Composite Index < > was up 35.25 points, or 2.05 percent, at 1,752.96.Google jumped 8.7 percent to $383.66 after reporting forecast-beating results late on Thursday that offered investors relief that the company could weather the economic downturn.
Shares of IBM rose 3.4 percent to $94.61 after the technology services company said it expects to meet long-term profit forecasts.
But some companies warned of quickly slowing economic growth.
Schlumberger Ltd <SLB.N>, the world's largest oilfield services company, warned that the credit crisis and softening global economy could trim spending expectations in the oil and gas industry next year. Its shares fell 5.6 percent.
Honeywell International Inc <HON.N> cut its fourth-quarter profit forecast below Wall Street's expectations and said it is bracing for "recessionary conditions" in the United States and Europe next year, sending its shares down 6 percent.
Analysts said options expirations could increase stock market volatility on Friday.
The FTSEurofirst 300 <
> index of top European shares closed up 4.2 percent at 894.77 points. The index has lost 39.9 percent this year on recession worries and the effects of banking failures.Oil groups BP <BP.L>, Total <TOTF.PA> and Royal Dutch Shell <RDSa.L> climbed between 8.6 percent to 9.7 percent after big declines the previous day.
Defensive drug stocks also rose. Roche <ROG.VX> and Novartis <NOVN.VX>, which report results next week, gained 10.4 percent and 12 percent, respectively.
"This is the most volatile week we've seen," said Thierry Lacraz, strategist at Swiss bank Pictet in Geneva. "The sole intelligent thing is to remain on the sidelines and not make any huge bets."
Longer-dated euro zone government debt rose, also in choppy trade, briefly pushing the 10-year yield below 4 percent for the first time in a week as the sour U.S. economic data underpinned demand for safer assets.
But U.S. government debt wavered as rising stocks tempered the flight to safety.
"Along with everyone else, the eyes of Treasuries investors are glued to what's going on in the stock market," said Chris Rupkey, chief financial economist at Bank of Tokyo/Mitsubishi. "When stocks go up, the bid for Treasuries goes down. When stocks go down, the bid for Treasuries comes back."
U.S. Treasuries pared gains to trade lower.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 6/32 in price to yield 3.99 percent, while the 2-year U.S. Treasury note <US2YT=RR> slid 2/32 in price to yield 1.66 percent.
The dollar rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.06 percent at 82.336.
The euro <EUR=> fell 0.24 percent at $1.3452. Against the yen, the dollar <JPY=> fell 0.01 percent at 101.59.
With signs of economic trouble now emerging in Eastern Europe and Asia, investors have reversed risky trades financed with low-yielding yen, helping lift the Japanese currency at the expense of its higher-yielding rivals, such as the euro.
Spot gold prices <XAU=> fell $14.50 to $790 an ounce.
Gold fell more than 3 percent, extending the previous session's losses, as the dollar firmed against the euro, and investors sold bullion to cover losses on other markets.
Enormous price volatility has taken a toll on investment sentiment, triggering margin calls and massive liquidation in the gold market, said Leonard Kaplan, president of Prospector Asset Management.
