PERTH, Oct 29 (Reuters) - Oil prices fell towards $77 a barrel on Thursday, extending the previous session's decline of 2.6 percent, as fears of a protracted economic recovery in the United States drove investors to continue to take profit from oil's recent rally.
Data this week from the United States has raised questions about a sustained recovery with consumer confidence dipping to recessionary levels and new home sales falling unexpectedly.
Concerns over the fragility of the health of the U.S. economy and weakness in energy demand have prompted oil prices to fall about 6 percent over five out of six trading sessions, since striking a one-year high of $82 on Oct. 21.
U.S. crude for December delivery <CLc1> fell 25 cents to $77.21 a barrel by 0213 GMT, after settling down $2.09 at $77.46 on Wednesday on government data that showed a surprise build in U.S. gasoline inventories last week.
London Brent crude <LCOc1> fell 22 cents to $75.64.
"U.S. economic data again included some positives and negatives but, in the context of commodity markets that have been looking at the prospects for international economic recovery, it was the negatives that were the surprise and grabbed the attention of investors," said David Moore, a commodities analyst at the Commonwealth Bank of Australia.
In a sign of investors' skittishness towards stocks and other riskier assets like commodities, the VIX indicator <.VIX>, Wall Street's favourite barometer for market sentiment, jumped 12.4 percent on Wednesday.
Analysts said traders were likely to remain wary ahead of the U.S. gross domestic product (GDP) data due later on Thursday.
The market is expecting the world's largest economy to expand 3.3 percent in the third quarter, but a lower growth figure could heighten concerns of a sluggish recovery and prompt a further sell-off in riskier commodities. [
]Asian shares tracked losses on Wall Street and fell on Thursday, with Japan's Nikkei index falling to a 3-week low.
The U.S. dollar held firm near its highest in more than two weeks on Thursday, while the yen strengthened broadly as investors took profits on a host of growth-linked trades that had been in vogue in recent months. [
]Sales of new U.S. homes unexpectedly tumbled in September, their first drop in six months, underscoring the hazards to an economic recovery even as businesses appeared to be stepping up investment. [
