What Is a Covered Warrant
A covered warrant lets you bet on an underlying stock price with small capital and high leverage. We explain how it works, the leverage, the risk of total loss, and how it differs from stocks.
Bet on a large stock with small capital
A covered warrant (CW) is a product on the Vietnamese exchange that lets you "bet" on the price movement of an underlying stock (usually a VN30 stock) with small capital and high leverage. It sounds attractive, but it comes with the risk of total loss — understand it well before buying.
How a covered warrant works
A covered warrant is issued by a securities firm, giving the holder the right (not the obligation) to the price difference of the underlying stock versus a "strike price," at the expiry date.
- Call warrant: profits when the underlying stock price rises above the strike price.
- You do not own the underlying stock — you only hold the warrant, trading it as a separate ticker on the exchange.
- Each warrant has a predefined strike price and expiry date.
A warrant price is usually much cheaper than the underlying stock price — that is the source of the leverage.
Leverage: big gains, big losses
Because it is cheap, a small move in the underlying stock can change the warrant price by a very large percentage:
- The underlying rises a few percent, so the warrant can rise tens of percent.
- But the reverse is also true — and much worse.
The biggest risk: total loss at expiry
This is the key difference from a stock. If at expiry the underlying stock does not exceed the strike price, a call warrant becomes worthless — you lose all the money you paid for it.
- Ordinary stock: if the price falls you have a loss, but it still has value.
- Warrant: it can go to zero at expiry if you bet the wrong direction.
There is also time-value decay: the closer to expiry, the more the warrant "time value" declines.
Versus stocks and derivatives
- Vs stocks: a warrant has high leverage, an expiry, and can become worthless — much riskier.
- Vs VN30 index futures: a warrant requires no additional margin (max loss = the purchase amount), but it is still a high-leverage short-term speculative tool.
Conclusion
A covered warrant lets you bet on an underlying stock price with small capital and high leverage, but it has an expiry and can become worthless if you bet the wrong direction. It is a high-risk short-term speculative tool, unsuitable for a long-term accumulation strategy. Beginners should understand it very well — and only use money they are willing to lose.
