When Purchase of shares...?

What is the care should be taken at the time of purchase of shares in a company....?

as the shares purchase is made from tax paid income, so the question of taxability does not arise at the time of purchase, though at time of purchase, certain taxes are applicable apart from brokerage, viz service tax, security transaction tax, etc.

as shares are part of capital asset, so there is no tax if we sell them after holding in demat for more than 365 days, this type of gain is LTCG, and is fully exempted u/s 10(36) if security transaction tax is paid at the time of sale.

if we sell them within 365 days then sec 111A applies and such gains ( sale price less cost price) is taxed at special rate of 15%.
