Why Buy Call Warrants on Stocks?
Leverage "Unlimited Gains with Limited Losses"

First and main point to remember is that warrantholders do not have to keep the warrant until maturity to make a profit. They can buy a warrant at launch date or after through the Stock Exchange and sell the warrant a couple of days, weeks or months later or hold on to it until maturity. The profit and loss profile will be different according to how long the warrantholder keeps the warrant.

The fundamental advantage of buying a call warrant, as opposed to a direct investment in the underlying asset, resides in the leverage effect that warrants offer. When buying warrants, the investor is required to outlay only a small proportion of the underlying asset price.

The leverage effect enables investors to gain exposure to the underlying through a small amount of money.

Example:
all warrants on Company A
(stock code: 9901.HK)
Terms and conditions as of launch date (15 Feb 00):
Maturity date
7 Sep 2000
Type
European-style call warrants
Underlying
Company A
Strike priceHKD 66.41
Converting ratio10 warrants for 1 share

On 30 May 2000, an investor could buy a minimum board lot (10,000) of SG Company A call warrants 9901.HK and invest as low as HKD 3,400.00 (10,000 x HKD 0.34) whereas direct investment in a board lot of shares required an investment of HKD 52,500 (1,000 x HKD 52.50).


Buy the Shares (dotted line)
On 30 May 2000, an investor buys 1,000 shares of Company A at HKD 52.50 with a total cash outlay of HKD 52,500.00. The investor then sells the shares on 20 Jun 2000 at HKD 65.00 for a gain of 23.80%.

Buy the Call Warrant and sell 3 weeks later
On 30 May 2000, instead of buying the shares the investor buys 10,000 call warrants 9901.HK at HKD 0.34 with total cash outlay of HKD 3,400.On 20 Jun 00 call warrant 9901.HK rose to HKD 0.86 making a gain of 153%.

Buy the Call Warrant and hold until maturity (plain line)
Alternatively, if the warrantholder held 9901.HK until maturity, the potential profit and loss profile would be like diagram 1. As one can see, using the call warrant strategy, the maximum loss at the time of maturity would be the full value of the call warrant while the maximum loss for the stockholder would be the full value of the stock.

Cash Extraction
Taking advantage of the leverage effect, investors already holding shares but needing cash can sell their shares and buy warrants to keep an exposure to the underlying.

Assuming no commission, transaction levy and stamp duty (to simplify calculation), the investor would receive the sale proceeds of HKD 87,250 (HKD 87.25 x 1,000) and pay HKD 27,250 (HKD 2.725 x 10,000) for purchasing the warrants. In the process, there is a cash extraction of HKD 60,000 (HKD 87,250 - HKD 27,250) while maintaining the exposure to Company B.


Buy the Call Warrant as Cash Extraction:
Example:
Call warrants on Company B
(stock code: 9902.HK)
Terms and conditions as of launch date (31 May 1999):
Maturity date
11 Dec 2000
Type
European-style call warrants
Underlying
Company B
Strike priceHKD 64.125
Converting ratio10 warrants for 1 share

On 26 Jul 2000 Company B closed at HKD 97.00 which is up 11.17% from where the investor sold his shares on 3 Jul 2000. However the investor did not miss out on these extra gains as the call warrant on Company B rose to HKD 3.60 which translates into a gain of 32.11% on the warrant price.

The 2 tables below show a comparison of the 2 strategies at different future prices of Company B on 26 Jul 2000. The total Value of the Cash Extraction Strategy is the value of the warrant and HKD 60,000 cash extracted from selling Company B shares on 3 Jul 2000. Note the Cash Extraction Strategy only underperformed slightly if Company B rose but outperformed by a wide margin on the downside if Company B should fall.
