What are Convertible Bonds? Why Learn About Them?
In the stock market, we constantly face a dilemma: if you want high returns, you must bear high risks; if you want low risks, you must accept low returns. But is there truly no investment tool that offers both offensive and defensive capabilities?
The answer is yes, and it is the core research subject of our cb lab — Convertible Bonds (CB).
What is a Convertible Bond: Differences from Stocks and Regular Bonds
A convertible bond, as the name suggests, is a "corporate bond that can be converted into stock". You can think of it as a combination of a "regular corporate bond" and a "stock call option."
| Feature | Stock (Common Equity) | Regular Corporate Bond | Convertible Bond (CB) |
|---|---|---|---|
| Price Volatility | High (No downside limit) | Low (Mainly affected by interest rates) | Medium (Follows stock price, but has a price floor) |
| Principal Protection | None, could delist to zero | Returns principal if no default | Returns face value (usually 100) if no default |
| Upside Participation | Full participation | None, fixed interest only | Convertible to stock, full participation in upside |
Why the "Downside Protection, Unlimited Upside" Trait?
This is the most fascinating aspect of convertible bonds, provided you have the correct understanding.
- Downside Protection (Bond Defense): Every convertible bond is issued with a face value (in Taiwan, it's typically quoted at 100). As long as the company does not default or go bankrupt, it must buy back the bond at a minimum price of 100 upon maturity. Take Senwei Energy (6806) as an example. The company suffered massive losses from offshore wind projects and was forced to delist, leaving regular shareholders with massive liquidity risks and losses. However, its convertible bond, "Senwei 1 (68061)", was a "secured convertible bond" guaranteed by a syndicate of banks. Even though the company delisted, investors holding Senwei 1 still received their principal back through the banks' guarantee. This is the ultimate downside protection of convertible bonds.
- Unlimited Upside (Stock Explosiveness): When a company's stock price surges and exceeds the agreed-upon "conversion price," the price of the convertible bond will rise in tandem with the stock. Take memory giant Macronix (2337) as an example. When the memory cycle turned upward and market demand exploded, the stock price skyrocketed well beyond the conversion price of "Macronix 2 (23372)". At that point, the price of Macronix 2 was no longer restricted by its face value of 100; it broke upward alongside the stock. As of today, the all-time high of Macronix 2 has even exceeded 700! Investors can fully participate in the massive upside of the soaring stock.
💡 In Summary: Limited Maximum Loss, Infinite Upside Potential Many beginners mistakenly believe that buying convertible bonds means "you will absolutely never lose money." This is only half right. The more precise definition of "downside protection" is that "your maximum loss is completely controllable."
For example: If you enter the market when a convertible bond has already surged to 120, even if the company's operations underperform and the stock price crashes, the company is only obligated to buy it back at the face value of 100 upon maturity. Your maximum capital loss per bond is strictly capped at 20 (about 20%). Unlike stocks, there is no risk of plunging from 120 all the way to zero.
Buying convertible bonds means trading a known maximum risk (the gap between your entry price and 100) for the infinite potential of doubling your money. This is why smart money and institutional investors love this tool so much.
Who Should Learn About Convertible Bonds?
If any of the following apply to you, convertible bonds are an absolute must-learn investment tool:
