Vertical Spread Option Strategies
A "vertical"
strategy, also known as a vertical spread, is one in which both long
and short options of the same type are held, using different strike prices,
with the same expiration date.
All vertical
spreads offer a limited and known-in-advance maximum risk, and a limited
and known-in-advance maximum gain.
Vertical
spreads are very popular with options traders, because there is a
vertical strategy to match almost any outlook for a stock. Because there
are a large number of possibilities, choosing the right vertical for the
situation can be confusing. This page attempts to clarify the choices
as much as possible.
First,
let's clarify what we mean by different strike prices. Using ATM,
OTM, and ITM quickly gets confusing when talking about both puts and calls
and a variety of strikes. Instead we'll use the designations below:

Bull
Call Vertical Debit Spread
- Description:
long call at one strike, short call at a higher strike.
- Outlook:
always at least partially bullish.
- Entry
is always a debit and does not require margin after entry.
- Max risk
is always the initial debit.
- Advantage
of a bull call: if stock is over the lower strike at expiration, the
long call can be exercised to buy stock if desired.
- For a
visual comparison, see All
Bull Call debit spread
graphs.
Bull
Put Vertical Credit Spread
- Description:
long put at one strike, short put at a higher strike.
- Outlook:
always at least partially bullish.
- Entry
is always a credit and holding the spread requires margin.
- Max risk
is always (the difference in strike prices x the number of shares represented
by contracts – the initial credit).
- Advantage
of a bull put: if stock price is over one or both strike prices at expiration,
the corresponding put(s) will expire worthless, saving commissions to
exit.
- For a
visual comparison, see All
Bull Put credit spread
graphs.
Bull Calls
and Bull Puts theoretically have the same profit graphs and same details,
except for the debit or credit entries. In the market, you may find slightly
better prices for one or the other, depending on the IV and relationship
of the current stock price to the strike prices used.
