Hi Anuj
I can tell you some good stock to invest . But first of all you must not invest al your money in one stock.
Decide how much loss can you bear before investing. This is stock market anything can happen no one knows whats next. But few good stock are as follows.
Tata Steel, NTPC,ITC,CASTROL,ACC,RANBAXY, ORCHID CHEMICALS, DENA BANK, SBI.
You will have to decide which one to invest in. All these stocks are fundamentaly and technically very good as per my suggestion.
