Well there are more than thousands of websites available in India which deals with guiding in the stock market, giving various calls time to time by doing analysis as per their own method and skills. Some calls are based on technical chart, some are based on the fundamentals of the stocks, some are based on news speculation whereas some are based on long term prospective. Its very difficult to point out or identify the best sites among them. These sites use to charge for giving this kind of service. So you have to become a premium customer for getting those calls and all.
However I would like to recommend the website of Mr S P Tulsian www.sptulsian.com
SP Tulsian is a very good reasearcher & analyst on fundamentals. He has the unique skills to do such research. He is a very smart professional in the stock market. You can think about Mr S P Tulsian.
One more site is www.moneyworks4me.com, you can also try this website for free with some limited features. But it is also a good site.
