Once you have picked a side, the next step in how to invest in the stock market is to get the basics right. Get the basic idea of what BSE, NSE, Sensex, and Nifty are. Try to know more about what stocks are, stock market timings, who is a stockbroker, how the market moves, etc. to get a general idea about the market.
In the bid to make quick money, most beginners often skip learning the basics. But if you are unaware of the basics, it will not be possible for you to build your own trading/investing strategies. Spend at least a few days mastering the basics so that you actually know what to do once you get yourself a trading account.
