Share Buyback

A share buyback is when a company repurchases its own shares from existing shareholders, reducing the number of shares outstanding. In India, buybacks are governed by SEBI's Buy-Back of Securities Regulations and most now happen through the tender-offer route.

In a tender-offer buyback, the company fixes a buyback price (usually at a premium to the market price), a record date, and a total buyback size. Eligible shareholders tender their shares in a set window, and if more shares are tendered than the company will buy, acceptance is proportionate. A portion of every tender-offer buyback is reserved for small shareholders (holdings up to ₹2 lakh by market value on the record date), which is why small investors often get better acceptance ratios than large ones. SEBI has been phasing out the alternative open-market route, making the tender route the standard.

Companies buy back shares to return surplus cash, to support the stock when management believes it is undervalued, to improve per-share metrics like EPS and return on equity, or to raise promoter holding percentage without a purchase (the promoters simply don't tender). The signal is usually read as management confidence, but the details matter: a small buyback relative to market cap moves little, and a buyback funded by debt or done while the business is starved of investment deserves skepticism.

Tax changed materially from 1 October 2024: buyback proceeds are now taxed in the shareholder's hands as dividend income at slab rates (the earlier company-level buyback tax is gone), with the cost of the tendered shares available as a capital loss. Factor this in before tendering — for investors in high tax slabs, the post-tax arithmetic of tendering versus selling on market can flip.

How stocks tend to react

Buyback announcements often lift the stock in the short term, especially when the buyback price carries a meaningful premium and the size is significant relative to free float. The reaction tends to fade if acceptance ratios are expected to be low, and the stock frequently drifts back toward its own fundamentals once the tender window closes. Reaction depends heavily on size, premium, and whether the market reads it as confidence or as a lack of better uses for cash.

MarketPing measures this instead of guessing: every analysed announcement carries the stock's actual price reaction across 14 horizons, and the Reaction Lab aggregates how each category of announcement has historically moved stocks.
