Cl,apter 24: Ratio Spreads Using Puts 359
|

expire worthless and the result would be a loss of commissions. However, there is
|
||||
downside risk. If XYZ should fall by a great deal, one would have to pay much more
|
||||
to buy back the two short puts than he would receive from selling out the one long
|
||||
put. The maximum profit would be realized if XYZ were at 45 at expiration, since the
|
||||
short puts would expire worthless, but the long January 50 put would be worth 5
|
||||
points and could be sold at that price. Table 24-1 and Figure 24-1 summarize the
|
||||
position. Note that there is a range within which the position is profitable - 40 to 50
|
||||
in this example. If XYZ is above 40 and below 50 at January expiration, there will be
|
||||
some profit, before commissions, from the spread. Below 40 at expiration, losses will
|
||||
be generated and, although these losses are limited by the fact that a stock cannot
|
||||
decline in price below zero, these losses could become very large. There is no upside
|
||||
risk, however, as was pointed out earlier. The following formulae summarize the sit
|
||||
uation for any put ratio spread:
|
||||
Maximum upside risk
|
||||
Maximum profit
|
||||
potential
|
||||
= Net debit of spread (no upside risk if done for
|
||||
a credit)
|
||||
= Striking price differential x Number of long
|
||||
puts - Net debit (or plus net credit)
|
||||
Downside break-even price = Lower strike price - Maximum profit potential +
|
||||
Number of naked puts
|
||||
The investment required for the put ratio spread consists of the collateral
|
||||
requirement necessary for a naked put, plus or minus the credit or debit of the entire
|
||||
position. Since the collateral requirement for a naked option is 20% of the stock
