Altman Z-Score Flags PSU Banks — Should You Panic?

Altman Z-Score Is Flashing Red on PSU Banks — But Read the Fine Print The Altman Z-Score is alarming investors in India's public sector banking space.

That's not a distressed cohort reading. That's a sector trading with identifiable value, where profitability metrics and earnings multiples are doing enough work to partially offset the structural leverage flags that the Z-Score is picking up. NSE: CANBK trades at roughly 1.1x book value with a return on equity that has recovered to the 15–17% range after years of provisioning drag.
