The primary market is buzzing again after a bit of a snooze, and at the centre stage this week is HDFC Bank’s subsidiary, HDB Financial’s mega Rs 12,500-crore public offer. After a four-month delay courtesy of the market regulator, the NBFC’s public offer is finally opening for bids from 25 to 27 June, with a price band set between ₹700 and ₹740 per share.
