Arbitrage trade on HPQ Options derivative
Posted by adminWell, I was delighted and to execute my first arbitrage trade, not sure if I am considered a Junior “Quant”.
The objective is to earn risk free through trades, scanning the market for floating risk free arb. Now I wish I could develop a machine solely for scanning floating prices like these.
This trade involves simultaneously Long the shares and short the In-the-money call option. In Hedge Fund terms, this is called a Relative Value Arbitrage. (Disclaimer: This is after all not a true risk free trade, because it involved using funds from my acct)
Analysis:
On 21 September 2010 10:30am, HPQ shot up from $39.5 to $40. As I am writing this post at 10:48am, HPQ is trading at $40.02.
The trade:
Ignoring the fundamentals of Hewlett-Packard Company (Public, NYSE:HPQ), we are also interested in its derivatives options market. It opened at $39.5, went up to $40 within 1 hour. The Options, HPQ Oct10 39 Call was price around $1.6+. Then it went to $1.7 when it hit a high of $40.05.
As a Call option Buyer
As a buyer, I would buy a HPQ Oct10 39 Call at $1.7. I would then be able to purchase 100 shares of HPQ at $39, but I have the option to exercise this option. If I do, I will be able to buy this at 100 shares at $39. I may then keep this shares, or sell on the open market at $40 (current price). Looking at maths, its stupid to spend $1.70 to a stock at $39, when you should be spending $1 to buy it at $39, since the stock is trading at $40.
As a Call option Seller
As an options seller selling an options to someone else, the other party buying my option will be able to buy the stocks @ my strike price. I am obligated to sell him at $39 per share. This could happen any time from now till expiration around mid October. In order for this Covered call to work, I need to buy 100 shares of HPQ at $40.05, and simultaneously sell/write the contract at $1.7 per contract for 100 shares. If I didn’t purchase 100 shares of HPQ while I wrote the options, I will be known as ‘Naked Call’.
So as a buyer, for $1.70, you have the option of buying 100 shares HPQ at $39. As a seller, I am forced to sell him my HPQ shares should he exercise his option, but I have already pocketed $173, so I am not concerned if he wants to exercise or not. Note that the current price is at $40.
For this arb covered call strategy to work, I bought on the open market 100 shares of HPQ at $40.05. I then sold the options of HPQ Oct10 39 Call at $1.73.
Using Maths:
100 x $40.05 = ($4005) (The money I had to have in order to complete this trade)
1 x $1.73 = $173 (Call option Sold short)
To sell @ $39 if he exercises:
$4005 – $3900 = $105 (amount I will lose if the buyer exercise his call option)
$173 – $105 = $68 (Potential gain locked-in if he exercises)
Now this strategy is suppose to be bullish. There are 2 downsides.
1) The option buyer decides not to exercise his call option. Then HPQ shares slides down. If it slides pass $38.32($40.05 – 1.73) within the expiration date, I will have to buy back the option (which I believe I will still gain), then sell off my 100 shares of HPQ at a lost. But this lost has already been hedged slightly by my options (Call option prices drop if the underlying stock prices move down, and vice versa). From $40 to $38.3, it will take quite a bit of hit, though there is still risk.
2) HPQ shares rallied to $45. The call option’s price will increase, while my profits have been limited because I have to sell the option buyer @$39, irregardless of how much the market price is, no matter how higher the price is, I still pocketed $68.
Summary
I made $173 if the shares of HPQ doesn’t move higher or lower, and definitely profit if it moves higher.
