Hi Business legends, i am noob(not even have basic of stock and online trading)

Nothing wrong to ask question. I'm responding very late. You need to understand the basics before deciding about trading/investment in share market. "Share Market" - term commonly used by many referring to buying/selling shares, a kind of business for people who has little knowledge on how things work. There are two things here, either you trade (many instruments are there like equity shares, future contracts, option contracts etc), either intraday (open and close position on same day) or positional (keep the position for more than a day), looking to make quick money OR buy equity/share of a company to hold for longer period to get benefited by price appreciation.

Where to start? Understand how market works, basic terms, risks involved etc. It is like a business, can't make money easily. People who miss this point, spend their savings and lose everything. None can teach better than self experience. It will take a year or two to settle down and to know your own style of trading/investing, to know about your strength and weakness. For example, I'm not good at intraday trading and so I don't do it. I buy shares for long term portfolio building, to create wealth in long run, like buying gold/land as an asset.

What makes one to make profit/loss? Maturity level, risk management, understanding of market, experience.

Last question: Pick companies that are in market for many years who is growing consistently in revenue and profit. May be 10-15% of companies only will go through this filter. There is risk always in investment. But we need to learn to contain that risk. Thats it.

Please post if you have any specific question.
