424 Part IV: Additional Considerations
|
||||
The stock transaction is a 12-point profit, since the stock was bought at 58 and is sold
|
||||
at 70 via the put exercise. The cost of the put - 11 ¾ points - is lost, but the arbi
|
||||
trageur still makes ¼-point profit. Again, this profit is equal to the arrwunt of the dis
|
||||
count in the option when the position was established. Generally, the arbitrageur
|
||||
would exercise his put option immediately, because he would not want to tie up his
|
||||
capital to carry the long stock. An exception to this would be if the stock were about
|
||||
to go ex-dividend. Dividend arbitrage is discussed in the next section.
|
||||
The basic call and put arbitrages may exist at any time, although they will be
|
||||
more frequent when there is an abundance of deeply in-the-money options or when
|
||||
there is a very short time remaining until expiration. After market rallies, the call
|
||||
arbitrage may be easier to establish; after market declines, the put arbitrage will be
|
||||
easier to find. As an expiration date draws near, an option that is even slightly in-the
|
||||
money on the last day or two of trading could be a candidate for discount arbitrage.
|
||||
The reason that this is true is that public buying interest in the option will normally
|
||||
wane. The only public buyers would be those who are short and want to cover. Many
|
||||
covered writers will elect to let the stock be called away, so that will reduce even fur
|
||||
ther the buying potential of the public. This leaves it to the arbitrageurs to supply the
|
||||
buying interest.
|
||||
The arbitrageur obviously wants to establish these positions in as large a size as
|
||||
possible, since there is no risk in the position if it is established at a discount. Usually,
|
||||
there will be a larger market for the stock than there will be for the options, so the
|
||||
arbitrageur spends more of his time on the option position. However, there may be
|
||||
occasions when the option markets are larger than the corresponding stock quotes.
|
||||
When this happens, the arbitrageur has an alternative available to him: He might sell
|
||||
an in-the-money option at parity rather than take a stock position.
|
||||
Example: XYZ is at 58 and the XYZ July 50 call is at 7¾. These are the same figures
|
||||
as in the previous example. Furthermore, suppose that the trader is able to buy more
|
||||
options at 7¾ than he is able to sell stock at 58. If there were another in-the-money
|
||||
call that could be sold at parity, it could be used in place of the stock sale. For exam
|
||||
ple, if the XYZ July 40 call could be sold at 18 (parity), the arbitrage could still be
|
||||
established. Ifhe is assigned on the July 40 that he is short, he will then be short stock
|
||||
at a net price of 58 - the striking price of 40, plus the 18 points that were brought in
|
||||
from the sale of the July 40 call. Thus, the sale of the in-the-money call at parity is
|
||||
equivalent to shorting the stock for the arbitrage purpose.
|
||||
In a similar manner, an in-the-money put can be used in the basic put arbitrage.
|
||||
Example: With XYZ at 58 and the July 70 put at 11¾, the arbitrage could be estab
|
||||
lished. However, if the trader is having trouble buying enough stock at 58, he might
