Indian stocks continued to drop dramatically Thursday, following a negative session on Wall Street the previous day. Investors are selling first and asking questions later as emerging markets continue to spiral to the downside across all of Asia.

Market players in the region are worried that inflation data could come in hot on Friday and political instability could arise surrounding the U.S.-India nuclear energy accord. The Communist Party of India said it will continue to oppose the nuclear agreement with the U.S., which has been stalled since 2005.

"Negative global cues coupled with inflation concerns and political uncertainty is a dangerous concoction for a market where sentiment is already weak. There is no clarity as to which way the market is headed, and given the scenario, traders chose to sell. I advise people to stay where they are until a clear trend emerges," said Hitesh Sheth of Prabhudas Lilladher.

China Recap

Stocks in mainland China and Hong Kong fell sharply Thursday after investors lost hope that the Chinese government will step in and introduce any market-supporting policies to save the falling market. Market expectations had been high coming into the session that the government would announced some type of bail out for investors. Traders said market sentiment is at all-time lows as investors continue to witness the market drop with no relief in sight.

"It seems nothing can rescue the market from the prevailing pessimism. Maybe it's time to take a break, have a cup of tea and just wait," said Xu Zhiyuan, an analyst at CapitalEdge Investment Management.

The Shanghai Composite Index plunged 168.67 points, or 5.7%, to 2,772.44, and Hong Kong's Hang Seng Index dove 528.19 points, or 2.3%, to 22,797.61. Here's a look at how some China-based American depositary shares traded in the U.S. on Thursday.

According to the Financial Times, Spain-based Telefonica ( TEF) hopes to acquire a 10% stake in Chinese wireless company China Unicom ( CHU - Get Report) to capitalize on the reorganization of the state-run telecommunication sector. Telefonica already controls a 7.2% stake in Chinese fixed-line carrier China Netcom ( CN - Get Report), which is set to be acquired by China Unicom under the reorganization plan. American depositary shares of China Unicom, which trade on the NYSE, moved lower by 2.3% to $18.97, and ADR shares of Telefonica dropped 1% to $80.39.

Chinese oil refiner ADRs soared in U.S. trading after news broke that the Chinese government will hike the price of gasoline and diesel fuel by at least 17% in an effort to slow down the country's growing appetite for energy. China Petroleum & Chemical ( SNP - Get Report) surged 7.9% to $112.64; PetroChina ( PTR - Get Report) rose 4.4% to $140.49; and Sinopec Shanghai Petrochemical ( SHI) added 2.9% to $42.03.

The government fuel-price hike announcement overshadowed Goldman Sachs' price target cut of PetroChina and China Petroleum & Chemical. Goldman said refining losses for both companies will expand due to surging global oil prices. The investment bank cut its price target on China Petroleum by 15% and for PetroChina by 4.7%.

Shares of China Eastern dove 3.9% to $33.25, and shares of China Southern lost 3.1% to $23.42.
