628 Part V: Index Options and Futu,
If the action results in a lower strike, it is known as rolling down; if it results in a hi§
er strike, it is rolling up.
This rolling action changes the profit potential of the position. If one rolls dov;
he gets more downside protection, but his upside is even more limited than it prei
ously was. Still, if he is worried about the stock falling lower, this may be a prop
action to take. Conversely, if the common is rallying, and the covered writer is mo
bullish on the stock, he can roll up in order to increase his upside profit potenti~(
course, by rolling up, he creates more downside risk if the common stock should sue
denly reverse direction and fall.
The PERCS holder can achieve the same results as the covered writer. He ca
effectively roll his redemption price down or up if he so chooses. His reasons fc
doing so would be substantially the same as the covered writer's. For example, if th
common were dropping in price, the PERCS holder might become worried that hi
extra dividend income would not be enough to protect him in the case of furthe
decline. Therefore, he would want to take in even more premium in exchange fo
allowing himself to be called away at a lower price.
Example: XYZ issued PERCS when both were trading at 35. Now, XYZ has fallen t<
30 with only a year remaining until maturity, and the PERCS holder is nervous abou
further declines. He could, of course, merely sell his stock; but suppose that ht:
prefers to keep it and attempt to modify his position to more accurately reflect hb
attitude about future price movements.
Assume the following prices exist:
XYZ Common: 30
XYZ PERCS: 31
XYZ January 40 call: 2
XYZ January 35 call: 4
Ifhe buys the January 40 call and sells the January 35 call, he will have accomplished
his purpose. This is the same as selling a call bear spread. As shown in the previous
example, buying the January 40 call is essentially the same as removing the redemp­
tion feature from the PERCS. Then, selling the January 35 call will reinstate a
redemption feature at 35. Thus, the PERCS holder has taken in a premium of 2
points and has lowered the redemption price.
If XYZ is below 35 when the options expire, he will have an extra $200 profit
from the option trades. If XYZ rallies and is above 35 at expiration, he will be effec­
tively called away at 37 (the striking price of 35 plus the two points from the rollr,
instead of at the original demand price of 39. In actual practice, if the January 35 call
