📌 Key Insight: When a company announces a rights issue, the stock trades under two labels: cum-rights (with rights) and ex-rights (without rights). The transition between these two states directly impacts a share's market price and your investment value.
What Is a Rights Issue?
A rights issue is when a listed company offers existing shareholders the right to buy new shares at a discount. It's a way for the company to raise fresh capital. The record date is the cutoff day. If you own shares on or before the record date, you get the rights. After the record date, the stock trades ex-rights, meaning new buyers do not receive the rights.
Company XYZ announces a 1-for-5 rights issue at $8 per new share. The current market price is $10. The record date is set for April 30.
- Cum-rights period: From announcement until April 29.
- Ex-rights date: April 30 onwards.
- Right: For every 5 shares you own, you can buy 1 new share at $8.
Cum-Rights ("With Rights")
Cum-rights means the share is trading with the entitlement to the rights issue attached. If you buy cum-rights shares, you are also buying the right to purchase additional shares at the discounted price. The market price during this period is higher because it embeds the value of the right.
Using Company XYZ:
- Market Price (Cum-rights): $10
- Rights Issue: 1-for-5 at $8
- Theoretical Ex-Rights Price (TERP):
[(5 old shares * $10) + (1 new share * $8)] / (5 + 1) = $9.67
The value of one right is: $10 (Cum-price) - $9.67 (TERP) = $0.33.
Ex-Rights ("Without Rights")
Ex-rights means the share is trading without the rights entitlement. This happens from the ex-rights date onward. The stock price adjusts downward on this day because the valuable right has been removed. New buyers of ex-rights shares do not get the right to participate in the discounted issue.
On the ex-rights date (April 30), Company XYZ's stock opens at the Theoretical Ex-Rights Price (TERP) of $9.67.
- An investor who bought cum-rights shares at $10 still holds the right. They can now either exercise it (buy new shares at $8) or sell the right.
- An investor who buys ex-rights shares at $9.67 gets only the share, with no attached right.
| Aspect | Cum-Rights Shares | Ex-Rights Shares |
|---|---|---|
| Trading Period | From announcement until the record date. | From the ex-rights date onward. |
| Rights Entitlement | Includes the right to buy new shares at a discount. | Does NOT include the right. |
| Market Price | Higher, as it includes the value of the right. | Lower, adjusted to Theoretical Ex-Rights Price (TERP). |
| Buyer's Benefit | Gets both the share and the subscription right. | Gets only the share. |
| Price Adjustment | N/A (price is pre-adjustment). | Price drops on the ex-date to reflect rights removal. |
Why the Distinction Matters for Investors
Understanding cum-rights vs. ex-rights is crucial for making informed decisions and avoiding confusion around price changes.
⚠️ Common Pitfalls & Misconceptions
- Mistaking a price drop for a loss: When a stock goes ex-rights, the price falls. This is a mechanical adjustment, not a market-driven loss for existing shareholders who hold the rights.
- Ignoring the record date: To be eligible for the rights, you must own the shares before the ex-date. Buying on the ex-date means you miss out.
- Overlooking the right's value: The right is a separable, tradeable asset. Shareholders can sell their rights in the market if they don't want to invest more capital.
Practical Scenarios and Outcomes
Let's see how different investor actions play out.
Sarah owns 100 shares of XYZ bought at $10 cum-rights.
- She receives rights to buy 100 / 5 = 20 new shares at $8 each.
- On ex-date, share price adjusts to $9.67.
Sarah's choices:
1. Exercise: Pay 20 * $8 = $160 to get 20 new shares. Her average cost per share across 120 shares becomes [(100*$10) + (20*$8)] / 120 = $9.67.
2. Sell Rights: Sell her 20 rights at market value (~$0.33 each) for about $6.60 cash.
John buys 100 shares of XYZ on the ex-rights date at $9.67 per share.
- He pays 100 * $9.67 = $967.
- He does not receive any rights to the discounted issue.
- His cost basis is simply $9.67 per share.
Conclusion
The cum-rights and ex-rights labels mark a critical timeline in a rights issue. Cum-rights shares carry a premium for the attached subscription right. Ex-rights shares trade at a lower, adjusted price without the right. For shareholders, the ex-date price drop is a neutral accounting event, not a loss, because the right's value is retained. For new buyers, ex-rights shares offer a clean entry at the adjusted fair value. Understanding this distinction prevents misinterpretation of price movements and enables strategic decisions about participating in or bypassing a capital raise.
