Stocks in India snapped a three-day down trend on Thursday but not without experiencing extremes in volatility that saw the benchmark Sensex Index swing 500 points intraday. Traders appear to be putting aside any negative sentiment created by the fuel price hike and snapping up stocks they deem to be undervalued. The Sensex Index had plunged more than 900 points over the past three trading sessions.

"There is a lot of volatility in the market. Unless it gains some stability, it is difficult to take a call on the direction. Nevertheless, valuations are attractive at this stage," said Jignesh Shah of ABN Amro Bank.

The Bombay Stock Exchange's Sensex Index slipped 254.93 points, or 1.64%, to 15,769.72. Here's a look at how some India-based American depositary shares traded in the U.S. on Thursday.

Stifel Nicolaus & Company said it will keep its hold rating on shares of Infosys Technologies ( INFY) but raise its estimates for the Indian information technology firm. In a note to clients a Stifel analyst said due to the Indian government's approval of a one-year extension of the software technology park tax exemption, it is raising its EPS estimates for 2009 from $2.47 to $2.54 and for 2010 from $2.79 to $2.82. American depositary shares of Infosys, which trade on the Nasdaq, surged 5.7% to $49.37.

Stifel Nicolaus & Company also reiterated its buy rating for U.S.-based information technology provider Cognizant Technology Solutions ( CTSH) and set its price target at $41. Stifel raised its EPS estimates for 2009 from $1.74 to $1.93 and for 2010 from $2.15 to $2.16, citing the software technology park tax exemption.

India-based commercial bank ICICI Bank ( IBN) said growth in the real estate market has been negatively impacted due to higher interest rates and rising home prices but the sector isn't in a bubble. "Clearly there is a slowdown in the number of deals. Interest rates have gone up from 8% in the past to now 12% and prices too have gone up but an asset bubble is not there," said ICICI Bank Joint Managing Director Chanda Kochhar.

The company also announced its private equity division ICICI Venture Funds Management Company will take a 20% stake in PVR Pictures, a wholly owned subsidiary of India-based film and entertainment company PVR Ltd, for 600 million rupees. Shares of ICICI jumped 5.5% to $36.95.

China Recap

Shares in mainland China dropped Thursday on speculation the government will initiate price controls on coal, oil and steel to combat rising inflation. Shares in the Far East also came under selling pressure after regulators announced they will review a plan by China State Construction Engineering for a multibillion-dollar IPO. Analysts are predicting the company will attempt to raise $5.8 billion.

"Investors are worried other big IPOs will be launched soon after China State Construction Engineering and drain liquidity," said Ding Chaoyu, an analyst at United Securities.

The Shanghai Composite Index dropped 18.27 points, or 0.54%, to 3,351.65 and Hong Kong's Hang Seng Index advanced 132.04 points, or 0.6%, to 24,255.29. Here's a look at how some China-based American depositary shares traded in the U.S. on Thursday.
