Balmer Lawrie - a great opportunity to invest in a Navratna

With the formation of National Land Monetisation Pipeline, I think if the Govt is thinking to seriously monetise unused land and buildings, this stock can provide decent returns.

It comes with the set of risks since many people have been invested for many years considering the same. But forming a dedicated company for this specific purpose can initiate the process. I used to have a position in Balmer Lawrie but exited a few months back.

Considering Balmer Lawrie investments this time, it has 10.6 crores shares of Balmer Lawrie - 10.6 x 118 = appx 1200 cr. Market cap of appx 880 crore of BL Invest gives a holding company discount of 30% but in this case since BLI is performing only the function of a holding company and nothing else, wouldnt the discount start shrinking once the asset sale starts ?
Are there any precedents of such situation, if anyone can throw some light, would be worth while!
