ADR Report-ADRs fall as risk aversion resurfaces

* Emerging market ADRs lead sell-off

* PetroChina earnings disappoint

* Bank of New York Mellon index of ADRs .BKADR falls 2.6

NEW YORK, Oct 28 (Reuters) - Overseas shares traded in the United States fell sharply on Wednesday, led by emerging market stocks as renewed concerns about the global economy sparked a sell-off in riskier assets around the globe.

New York-traded shares of PetroChina (PTR.N) , the world's second-most valuable oil and gas producer nose-dived on disappointing third-quarter results. Sector peer Sinopec Corp (SNP.N), due to report results later in the week, also slid.

Also in Asia, Nomura Holdings Inc (NMR.N) , Japan's largest investment bank, posted its biggest profit in nine quarters, helped by solid trading gains. The results pushed up its New York-listed shares and limited losses in the Japanese overseas share index .BKJP.

The Bank of New York Mellon index of leading American Depositary Receipts (ADRs) .BKADR fell 2.6 percent while the U.S. benchmark S&P 500 index .SPX lost 1.4 percent.

PetroChina shares slid 5.5 percent in New York after a 23.5 percent slide in earnings that was substantially worse than analysts had expected. Shares in Sinopec, slated to report late Thursday or early Friday, fell 3 percent.

Investors fear Sinopec may fall victim to a double whammy of regulated fuel prices at home and an uncertain outlook for crude oil. For more on this story, see [ID:nHKF080493] and [ID:nHKG140384]

The Bank of New York Mellon index of leading Asian ADRs .BKAS fell 2.9 percent. In Asia, shares fell in overnight trading. Japan's Nikkei .N225 hit a two-week closing low while in Taiwan the TAIEX index suffered its heaviest drop in three weeks. See [.T] and [.TW]

Nomura's second straight quarter of profits was a bright spot in Asia as it bounced back from an annual loss of more than $7 billion last year. Nomura New York-traded shares rose more than 2 percent.

U.S.-listed shares in companies from the emerging markets of Latin America were having their worst day in four months as the Bank of New York Mellon index of leading Latin American ADRs .BKLA fell 4.7 percent, tracking losses in major Latin American benchmarks.

Shares in Mexico's Cemex (CX.N), the world's No. 3 cement maker, lost 6 percent after the company posted weaker-than-expected results late on Tuesday and cut it earnings outlook for 2009 after off-loading its Australian assets.

In Europe the FTSEurofirst 300 .FTEU3 index of top shares fell 1.9 percent, its largest fall in 10 weeks that brought the index to a three-week closing low. See [.EU].

The sell-off carried through to European shares listed in New York and the Bank of New York Mellon index of leading European ADRs .BKEUR fell 2.3 percent.

Shares of Spanish bank Santander (STD.N) fell 2.6 percent after the euro zone's largest bank by market value posted a drop in nine-month net profit as it boosted provisions for an expected rise in bad debts from Spain's housing boom hangover. See, [ID:nLS477783]
