Thyrocare Share Price Falls 65% Even as Shares Turn Ex-Bonus for 2:1 Issue
On 28 November 2025, Thyrocare’s stock price shocked many investors. The share price dropped almost 65% in a single day. At first glance, this fall looked scary. But the real reason was very simple. The stock turned ex-bonus for its 2:1 bonus issue. That means the company gave two extra shares for every one held. When this happens, the market adjusts the price to match the new share count. So the lower price did not mean a sudden loss in the company’s value. It was only a math change.
Still, the sharp drop created confusion among new investors. Many thought something was wrong with the business. But the company’s operations did not change overnight. Only the price per share changed. The total value of an investor’s holding stayed almost the same. This event is a good reminder that bonus issues can cause big price swings, even when nothing bad is happening behind the scenes.
Thyrocare Share Price: What happened after the ex-bonus Date?
Thyrocare’s board declared a 2:1 bonus issue on 14 October 2025. The company fixed 28 November 2025 as the record date. The deemed allotment date is 1 December 2025, and the bonus shares were scheduled to begin trading on 2 December 2025.

On 28 November 2025, the stock opened much lower. The fall was about two-thirds from the previous day’s close. This shift matched the planned bonus ratio. The company’s exchange filing and public notices set the official dates and details.
Why the Per-Share Price Plunged but Value Stayed the Same?
A 2:1 bonus gives two extra shares for every one held. That triples the number of shares an investor owns. The market then adjusts the per-share price to reflect the larger share base. This is a mechanical change. It does not erase company assets or cash. For example, the stock’s closing price on 27 November 2025 was about ₹1,473.90.

After the ex-bonus adjustment on 28 November 2025, an equivalent theoretical price came near ₹492, roughly one-third of the prior level. This math explains the near 66-67% drop seen in trading. Investors should view this as a split-style adjustment, not a collapse of business value.
Thyrocare Share Price: How markets react on the Ex-Bonus Day?
Trading became noisy on 28 November 2025. Volume spiked, and quotes showed wide intraday swings. Many retail traders mistook the lower per-share quote for poor performance. Brokers and market analysts urged calm, noting the drop was expected. Some short-term speculators used the event to trade volatility.
Others liquidated positions out of confusion. Historical patterns show similar corporate actions often cause temporary disorder. The immediate market cap, when adjusted for share count, roughly reflected pre-bonus value.
Operational Context and Recent Performance
Thyrocare’s business did not suffer a sudden setback on the ex-bonus date. The company reported strong FY26 momentum and large gains earlier in the fiscal year. Management cited improved volumes and revenue growth in public communications before the bonus proposal.

Earlier in October 2025, a promoter sale of roughly 10% drew attention; that transaction and the bonus announcement were separate corporate moves and should be read independently. The bonus likely aims to widen retail ownership and boost liquidity after a period of strong share gains.
Practical Steps Investors Should Follow Now
Check the demat account for bonus credits after the allotment date of 1 December 2025. Confirm that holdings multiply by three, as expected. Recalculate the total holding value by multiplying the new share count by the prevailing price. Avoid snapping to conclusions based only on the per-share number.
If any discrepancy occurs, contact the broker or registrar with the allotment notice. For investors who track metrics per share, such as earnings per share, adjust historical figures to reflect the enlarged share base before making comparisons.
What does the Event mean for Liquidity and Price Discovery?
A bonus issue often makes the stock more affordable at the per-share level. That can attract small investors and improve market depth. Short term, liquidity can be choppy as traders reposition. Medium term, increased free float may help smooth price discovery. However, a bonus does not alter cash flow, profit margins, or strategic positioning. Any long-term revaluation must come from real business progress.
A Sensible Investor Mindset after the Drop
Do not treat a mechanical fall as a signal to panic. Review fundamentals, not just share price. Check revenue trends, margins, and recent announcements. Be mindful that corporate actions create technical price shifts. If active trading is not the goal, hold steady until the market digests the new share base and price stabilizes.
Using data wisely helps avoid rash decisions. For those who use advanced tools for screening, a single scan by an AI stock research analysis tool can quickly adjust historical per-share metrics to the new share count.
Closing Note
The sharp per-share fall on 28 November 2025 was largely arithmetic. The bonus issue tripled shares and reduced the price per share proportionally. The company’s operations, cash flows, and strategic position did not change simply because of the bonus. Investors should focus on core metrics and on whether the company can sustain growth and margins. Monitor allotment confirmations on 1 December 2025 and the start of trading of bonus shares on 2 December 2025 for final settlement and liquidity signals.
