Share Buyback: Risk, Profit, Tender Window, Record Date & Strategy (2026)

📌 What Is a Share Buyback?

A share buyback is when a company repurchases its own shares from existing shareholders. This reduces the total number of outstanding shares in the market.

• Improves Earnings Per Share (EPS)
• Signals company confidence
• Returns excess cash to shareholders
• Supports stock price during volatility

Example: If a company announces buyback at ₹1,200 while CMP is ₹950, investors may try to buy shares hoping to tender them at higher price.

🗓️ What Is Record Date in Buyback?

The record date is the cut-off date to determine eligible shareholders for the buyback.

• You must own shares before the ex-date.
• Shares must be in your Demat account on record date.
• T+1 settlement now applies in India.

Important: Buying shares on record date itself does NOT make you eligible.

🪟 What Is Tender Window?

The tender window is the period when eligible shareholders can offer (tender) their shares back to the company.

• Usually open for 5–10 working days
• You place tender request via broker
• Final acceptance depends on Acceptance Ratio

📊 What Is Acceptance Ratio?

Acceptance Ratio (AR) determines how many of your tendered shares will actually be bought.

If AR = 30% and you tender 100 shares → Only 30 shares will be accepted. Remaining shares return to your Demat.

Retail category (holding ≤ ₹2 lakh on record date) usually gets better acceptance ratio.

💰 How Profit Is Calculated?

Example Scenario:

• Buy Price: ₹950
• Buyback Price: ₹1,200
• Shares Bought: 100
• Acceptance Ratio: 40%

Accepted Shares = 40 Profit per accepted share = ₹250 Total Profit = ₹10,000

But remaining 60 shares will trade at market price — which may fall after record date.

⚠️ Risks in Share Buyback Strategy

• Low Acceptance Ratio — Profit may reduce significantly.
• Price Fall After Record Date — Stock often drops once eligibility passes.
• Opportunity Cost — Capital blocked for weeks.
• Market Crash Risk — If overall market falls, stock can drop sharply.
• Tax Considerations — Though buyback proceeds are tax-free for investors (company pays tax), remaining shares sold later may attract capital gains tax.

⚠️ Many beginners calculate profit assuming 100% acceptance — which rarely happens.

📈 Types of Buybacks in India

• Tender Offer Buyback — Most common for retail strategy.
• Open Market Buyback — Company buys from market gradually.

Tender offer gives fixed price; open market buyback does not guarantee exit price.

🧠 Smart Strategy Tips

• Prefer fundamentally strong companies.
• Check past buyback acceptance ratios.
• Avoid chasing if stock already rallied heavily.
• Consider partial hedge strategy.
• Track promoter participation.

Buyback works best when stock is fundamentally strong and market is stable.
