Buy Unlisted Shares

I can’t say about the probability, but there is always a risk of the IPO coming for less. I was mighty worried as my purchase of the Tata Tech stars was at 813, while the pink papers were suggesting IPO at 250.
Reliane Retail simply extinguished its equity held by public (they called it reduction) and bought my shares at 1300, whereas I had bought at 2500!

I feel my recent buy of vikram solar is also expensive.

So, nobody can predict about the unlisted shares.
