Buying Puts in Conjunction
with Call Purchases
There are several ways in which the purchases of both puts and calls can be used to
the speculator's advantage. One simple method is actually a follow-up strategy for the
call buyer. If the stock has advanced and the call buyer has a profit, he might con­
sider buying a put as a means of locking in his call profits while still allowing for more
potential upside appreciation. In Chapter 3, four basic alternatives were listed for the
call buyer who had a profit: He could liquidate the call and take his profit; he could
do nothing; he could "roll up" by selling the call for a profit and using part of the pro­
ceeds to purchase more out-of-the-money calls; or he could create a bull spread by
selling the out-of-the-money call against the profitable call that he holds. If the
underlying stock has listed puts, he has another alternative: He could buy a put. This
put purchase would serve to lock in some of the profits on the call and would still
allow room for further appreciation if the stock should continue to rise in price.
Example: An investor initially purchased an XYZ October 50 call for 3 points when
the stock was at 48. Sometime later, after the stock had risen to 58, the call would be
worth about 9 points. If there was an October 60 put, it might be selling for 4 points,
and the call holder could buy this put to lock in some of his profits. His position, after
purchasing the put, would be:
Long l October 50 call at 3 points N t t 7 • t - e cos: pom s Long l October 60 put at 4 points
He would own a "strangle" - any position consisting of both a put and a call with dif­
fering terms - that is always worth at least 10 points. The combination will be worth
exactly 10 points at expiration if XYZ is anywhere between 50 and 60. For example,
