I'm 22 amd i want to invest in secondary market. When i am 20 i invested 20k in the seconday market but I didnt buy by analysis. I bought that share with my friend by randomly " yesko price hike hunxa re" after that i didnt buy any share upto now even though i am that share till now and other allocated ipos . But now i want to buy with some analysis of my own but i have no idea how to analysis , which share to buy so i need some genuine advice regarding this .
