To invest in a stock market, you must open a Demat and trading account with a broker or intermediary. Upon successfully opening the account, you need to shortlist the right stock for your investments and invest through your account. Investing in stocks is a high-risk proposition. You must actively track your investments and take quick buy and sell decisions. Mutual funds are an excellent alternative to stock investing. Mutual funds invest in a basket of stocks and are managed by professional fund managers.
