Shares of Kotak Mahindra Bank appeared to plunge more than 80 percent on Wednesday, January 14. However, the dramatic fall is entirely optical and linked to the bank’s 5:1 stock split, which came into effect today.

Kotak Mahindra Bank shares are trading ex-split today, with the face value reduced to Re 1 per share from Rs 5. As part of the corporate action, one existing equity share has been sub-divided into five equity shares, with the stock price adjusting proportionately.

Why Kotak Mahindra Bank stock shows 80 percent fall, and where it really stands

On platforms that do not automatically adjust historical prices for the split, the stock appears to be down nearly 80 percent. This is simply the mathematical adjustment from the pre-split price to the post-split price, not a sell-off. Once adjusted for the split, Kotak Mahindra Bank stock was trading around Rs 419-420, down about 1.6 percent on the day.

On a split-adjusted basis, Kotak Mahindra Bank shares are trading comfortably within their recent range, with a 52-week low of about Rs 346 and a high near Rs 460. The bank’s market capitalisation, adjusted for the split, is around Rs 83,500 crore, and the stock is up over 9 percent over the past one year.

What happens to investors’ shares in their demat accounts

For shareholders, the split does not change the value of their investment. Instead, it changes the number of shares held and the price per share.

If an investor held 1 share of Kotak Mahindra Bank before the split, that holding automatically becomes 5 shares in the demat account after the record date. Correspondingly, the share price adjusts to roughly one-fifth of the earlier level. The total investment value remains the same, barring normal market fluctuations.

No action is required from investors. The additional shares are credited automatically to demat accounts, and the revised quantity becomes visible once the corporate action is fully processed by the depositories. The split is primarily aimed at improving liquidity and affordability, making the stock more accessible to a wider set of retail investors without altering fundamentals.

Kotak Mahindra Bank’s stock split history

This is not the first time the lender has split its shares:

• January 14, 2026: Face value reduced from Rs 5 to Re 1 (5:1 split)
• September 13, 2010: Face value reduced from Rs 10 to Rs 5 (2:1 split)

In both instances, the objective was to enhance trading liquidity and broaden investor participation, without impacting the underlying valuation.

Kotak Mahindra Bank stock call: ‘Buy’

Separately, brokerage commentary on Kotak Mahindra Bank shares continues to be driven by medium-term fundamentals rather than today’s corporate action. An HDFC Securities institutional research report this week maintained a constructive view on the lender’s stock. The report pointed to steady growth prospects, improving deposit quality, and resilient profitability, even as the bank navigates trade-offs between growth, margins, and asset quality.

The brokerage reiterated a ‘Buy’ stance with a sum-of-the-parts target price of Rs 2,500 (pre-split), reflecting confidence in the franchise despite sector-wide challenges.
