Corporate Actions & Their Impact
Five key corporate actions that affect stock prices — dividends, bonus issues, stock splits, rights issues, and share buybacks explained.
Dividends
A dividend is a portion of a company's profit distributed to its shareholders. It is one of the most direct ways investors earn returns from holding stocks, apart from capital appreciation.
- Dividends are declared by the board of directors and approved by shareholders at the Annual General Meeting (AGM).
- They are usually expressed as a fixed amount per share (e.g., Rs.10 per share) or as a percentage of face value.
- Only shareholders who hold the stock on or before the record date are eligible to receive the dividend.
Types of Dividends
| Type | Description |
|---|---|
| Interim dividend | Declared during the financial year before annual results are finalised. Reflects confidence in ongoing earnings. |
| Final dividend | Declared after the financial year ends, usually at the AGM. Based on the full-year profits. |
| Special dividend | A one-time payment outside the regular cycle, often when a company has exceptional profits or sells a large asset. |
Impact on Stock Price
On the ex-dividend date, the stock price typically drops by approximately the dividend amount. This is because new buyers after this date are not entitled to the declared dividend, so the market adjusts the price downward to reflect this.
Bonus Issue
A bonus issue is when a company issues additional shares to existing shareholders free of cost, in proportion to their current holdings. The shares are issued from the company's accumulated reserves.
For example, in a 1:1 bonus issue, a shareholder holding 100 shares will receive 100 additional shares — taking their total to 200 shares. The company's total market capitalization stays the same, but the number of outstanding shares doubles, so the price per share halves.
Why Companies Issue Bonus Shares
- To reward long-term shareholders without distributing cash.
- To improve liquidity of the stock by increasing the number of shares in circulation.
- To make the stock more affordable for retail investors after a significant price run-up.
- To signal confidence in future earnings and the company's financial health.
Impact on Price
The stock price adjusts proportionally on the ex-bonus date. In a 1:1 bonus, if the share price was Rs.500 before the bonus, it would adjust to approximately Rs.250 after. The total value of your holding remains the same — you simply own more shares at a lower price per share.
Stock Split
A stock split is when a company divides its existing shares into multiple shares by reducing the face value. The total market capitalization remains unchanged — only the number of shares and price per share change.
For example, in a 1:5 stock split (face value reduced from Rs.10 to Rs.2), a shareholder holding 100 shares at Rs.1,000 each will now hold 500 shares at Rs.200 each. The total value remains Rs.1,00,000.
Why Companies Split Stocks
- To make shares more affordable for retail investors when the price has risen significantly.
- To increase the number of shares in circulation, improving trading liquidity.
- To broaden the shareholder base by attracting smaller investors.
Impact
Like a bonus issue, a stock split does not change the fundamental value of the company or your total investment. The price adjusts proportionally on the ex-split date. However, the improved affordability and liquidity can sometimes lead to positive market sentiment and increased demand.
Rights Issue
A rights issue is when a company offers existing shareholders the right to purchase additional shares at a discounted price, in proportion to their current holdings. Unlike a bonus issue, the shareholder must pay for the new shares.
For example, in a 1:5 rights issue at Rs.100 per share (when the market price is Rs.200), a shareholder holding 500 shares can buy up to 100 additional shares at the discounted price of Rs.100 each.
Key Points
- Rights issues are used by companies to raise fresh capital for expansion, debt reduction, or working capital needs.
- Shareholders can choose to exercise their rights (buy the shares), renounce them (sell the entitlement to someone else), or let them lapse.
- The rights entitlement is tradable on the exchange during a specified window.
- If you do not exercise or sell your rights, your ownership percentage in the company will be diluted.
Ex-Rights Price
After a rights issue, the theoretical ex-rights price can be calculated using this formula:
Using the example above: (Rs.200 x 5 + Rs.100 x 1) / 6 = Rs.1,100 / 6 = Rs.183.33
Buyback of Shares
A buyback (or share repurchase) is when a company purchases its own shares from the open market or through a tender offer. The bought-back shares are extinguished, reducing the total number of outstanding shares.
Why Companies Buy Back Shares
- To return excess cash to shareholders in a tax-efficient manner (compared to dividends).
- To increase earnings per share (EPS) and return on equity (ROE) by reducing the share count.
- To signal to the market that the management believes the stock is undervalued.
- To prevent dilution from employee stock option plans (ESOPs).
How It Works
A buyback can be executed through the open market (the company buys shares on the exchange like any investor) or through a tender offer (the company offers to buy shares at a fixed price, usually at a premium to the market price). Shareholders can choose whether to participate in a tender offer.
Impact
Buybacks generally have a positive impact on stock prices. The reduced share count increases EPS, and the buyback itself signals management confidence. In a tender offer, shareholders who participate receive an immediate premium. Those who don't participate benefit from owning a larger percentage of the company.
Summary Table
Here is a quick comparison of all five corporate actions and their key characteristics:
| Corporate Action | Shares Change? | Price Impact | Cash to Investor? |
|---|---|---|---|
| Dividend | No | Drops by ~dividend amount on ex-date | Yes — cash payout |
| Bonus Issue | Yes — increases proportionally | Adjusts down proportionally | No — free shares instead |
| Stock Split | Yes — increases by split ratio | Adjusts down by split ratio | No |
| Rights Issue | Yes — if investor subscribes | Adjusts to ex-rights price | No — investor pays for shares |
| Buyback | Yes — decreases (shares extinguished) | Generally positive | Yes — if investor participates |
- Dividends are a direct cash reward to shareholders — but the stock price drops by approximately the dividend amount on the ex-date.
- Bonus issues and stock splits increase the number of shares you hold but do not change the total value of your investment.
- Rights issues let you buy additional shares at a discount — not exercising them leads to ownership dilution.
- Buybacks reduce the total share count, boosting EPS and often signalling management confidence in the stock.
- Dividend income exceeding Rs.5,000 from a single company attracts TDS at 10%.
- Always track the ex-date and record date of corporate actions — they directly affect your eligibility and the stock price.
