NEW YORK, Jan 23 (Reuters) - U.S. stocks fell on Thursday, with the Dow Jones industrial average recording its third consecutive day of losses, as risky assets sold off in wake of disappointing manufacturing data in China.
Financials and materials stocks were the day's biggest losers while telecom services was the only positive sector as investors sold growth-oriented stocks and bought defensive ones. Trading volume was heavier than in recent sessions.
The market sentiment was dented by a report on manufacturing in China which showed a mild slowdown at the end of 2013 in the world's second-largest economy had continued into the new year.
U.S.-traded Chinese stocks were down sharply after a U.S. Securities and Exchange Commission judge ruled that the Chinese units of the world's top accounting firms should be suspended from auditing those companies.

The CBOE Volatility index VIX often used as a fear gauge on Wall Street, closed up 7.2 percent at 13.77 after rising more than 11 percent earlier.
"The day's panic was largely associated with China and I think it's a temporary reaction," said Randy Frederick, managing director of active trading and derivatives at Charles Schwab in Austin, Texas.
"If we have good corporate earnings from a couple of big names or good economic reports, I think we will be right back up to where we were a couple days ago."

Trading volume was higher than usual with 7.4 billion shares traded on all U.S. platforms compared to a five-day average of 6.7 billion shares, according to BATS exchange data. Both on the NYSE and Nasdaq, decliners beat advancers by a ratio of about 2 to 1.
