That's a possibility ... if it's your own money.

I'm pretty sure lotsofpulp's underlying question is, how would that - or any divestment - work when it's the PM's father-in-law which has the shares and is chairman emeritus?

Are all relatives within distance X supposed to divest? And if not, you can't become PM? Hopefully they all like you enough!

The point is he is invested in Infosys because his father in law is invested in Infosys. Nothing can change that, other than him no longer being related or caring about his father in law, and hence his wife.
