Tata Sons IPO buzz adds Rs 17,200 cr to m-cap of 5 group stocks. Who gains most?

Renewed Tata Sons IPO hopes sparked a sharp rally in five Tata Group stocks, adding over Rs 17,200 crore to their combined market value in less than an hour. The gains came after the RBI rejected Tata Sons’ request to surrender its CoR and directed it to comply with regulations for NBFC-Upper Layer entities, reviving expectations of a public listing.
