@ayush welcome to Wazua republic and back to the country.
No. 1 thing to do is to assess your risk profile and develop your investment philosophy.
If you choose well you will make more money than other passive asset classes like cash, bonds and real estate.
But shares are also volatile and will lose you money if you chose the wrong ones, trade at the wrong time or too often.
Evaluating yourself will help you to decide whether to invest for dividend income (with modest capital gains), or for capital gains (with meagre dividend), or build a balanced portfolio.
Back to your portfolio,
KPLC & Ken Re are good picks.
I think you are over exposed in Insurance, manufacturing and agriculture. Concentrate your forces on one share from each of those industries.
Add an ambitious local bank to your portfolio.
Get a stock with real estate exposure.
Life is short. Live passionately.
