Trading Options
Option is a legal agreement between buyer and seller to buy
or sell security at an agreed price in a certain period of
time. It is quite similar to insurance that you pay an amount
of money in order that your property is protected by the
insurance company. The difference between these two is option
can be traded whereas, insurance policy cannot be traded. There
are two types of option contracts; call options and put
options.
We buy call option when we expect the security price will go
up and buy put option when we expect the security price will go
down. We also can sell call option if we expect the security
price will go down and vice versa if we sell put option.
Usually, option is counted by contract, one contract equivalent
to 100 unit options. 1 unit option protects 1 unit share. So,
one contract protects 100 unit shares.
Before learning how to trade options, the terminologies used
in Option Trading that you need to know are as follow:
a) Strike price: Strike price is the price
that is agreed by both buyer and seller of the option to deal
with. That means if the strike price of the call option is 35,
seller of this option obligates to sell security at this price
to the buyer of this option even though the market price of the
security is higher than 35 if the buyer exercises the option.
Buyer of this option can buy a security with a price that is
lower than the market price. If the current market price is
$39, the buyer will earn $4.
If the security price is lower than the strike price, buyer
will hold the option and leave the option to expire worthless.
For put option strike price, buyer of the option has the right
to sell the security at the strike price to the seller of the
option. That means if the put option strike price is 30, seller
of this option obligates to buy the security at this price from
the buyer if he or she exercises the option even though the
market price is lower than this price.
If the market is $25, the option buyer will earn $5. It
looks like a lot of transactions have been involved; but
actually, seller of the option will not buy a security and sell
it to the buyer. The broker firm will do all the transaction
but the extra money that has used to buy the security has to be
paid by the seller. This means, if the seller loss $4, the
buyer will earn $4.
b) Out of the money, in the money and
near/at the money option: Option price comprises of time value
and intrinsic price.
Time Value + Intrinsic Value = Option Price
Time value is the amount of money that the option worth due
to the time the option has until its expiration date. Longer
the time the option has until its expiration date, higher the
time value of this option. Time value of an option will become
zero if the option has expired. Intrinsic value for in the
money call option is the difference between current market
security price and option strike price.
Conversely, in the money put option’s intrinsic value is the
difference between option strike price and current market
security price. If the current security price is lower than the
call option strike price, this option is an out of the money
option. It only has time value. Call option with strike price
that is lower than the current market security price is an in
the money option. This option has time value and also intrinsic
value. Near or at the money option is the option, which strike
price is close to the current market security price.
c) Delta value: Delta value shows the
amount of the option price will change when the security price
changes by $1.00. It is a positive value for call option and
negative value for put option. It ranges from 0.1 to 1.0. Delta
value for in the money option is more than 0.5 and out of the
money option is less than 0.5. Delta value for deep in the
money option usually is more than 0.9. If the option delta
value is 0.6, meaning that when the security price goes up $1,
option price will go up $0.60. If the security price goes up
$0.10, the option price will goes up $0.06. Usually, $0.06 will
round up to $0.10.
d) Theta value: Theta value is a negative
value, which shows the decay of the option time value. Option,
which has longer time to expiry, has lower absolute theta value
than option, which has shorter time to expiry. High absolute
theta value means the option time value decays more than the
low absolute theta value option. A theta value of -0.0188 means
that the option will lose $0.0188 in its premium after passage
of seven days. Options with a low absolute theta value are more
preferable for purchase than those with high absolute theta
value.
e) Gamma value: Gamma value shows the
change of the delta value of an option when the security price
increases or decreases. For an example, gamma value of 0.03
indicates that the delta value of this option will increase
0.03 when the security price goes up $1. Option, which has
longer time to expiry, has lower value of gamma than option,
which has shorter time to expiry. The gamma value also changes
significantly when the security price moves near the option
strike price.
f) Vega value: Vega value shows the change
of the value of option for one percent increase in implied
volatility. This value is always positive. Near the money
option has higher vega value compared to in the money and out
of the money option. Option, which has longer time to expiry,
has higher vega value than the option, which has shorter time
to expiry. Since vega value measures the sensitivity of the
option to the change of the security volatility, higher vega
value options are more preferable for purchase than those with
low vega value.
g) Implied volatility: Implied volatility
is a theoretical value, which is used to represent the
volatility of a security price. It is calculated by
substituting actual option price, security price, option strike
price and the option expiration date into the Black-Scholes
equation. Options with a high volatility stocks are cost more
than those with low volatility. This is because high volatility
stock option has a greater chance to become in the money option
before its expiration date. Most purchasers prefer high
volatility stock options than the low volatility stock
options.
Actually, there are twenty-one option trading strategies,
which most of the option investors and traders use in their
daily trading. However, I’m only introducing ten strategies as
follow:
a) Naked call or put
b) Call or put spread
c) Straddle
d) Strangle
e) Covered call
f) Collar
g) Condor
h) Combo
i) Butterfly spread
j) Calender spread
Naked call and put meaning buy call and put
option only at the strike price, which is close to the market
security price. When the security price goes up, the profit is
the subtracting of the security price to the strike price if
you buy call and the reverse if you buy put.
Call and put spread is established by
buying in the money or near the money option and selling out of
the money option. When the security price goes up, in the money
call option that you buy will generate profit and the out of
the money option that you sell will loss money. However, due to
the difference of the delta value, when the security price goes
up, in the money call option price goes up with a higher rate
compared to the out of the money call option.
When you deduce the profit from the loss, you still earn
money. The purpose of selling the out of the money option is to
protect the depreciation of time value of in the money call
option, if the security price goes down. However, if the
security price continuously goes down, this will cause an
unlimited loss. Therefore, stop loss has to be set at certain
level. This strategy also has a maximum profit that is when
security price has crossed over in the money option strike
price.
Straddle can earn money no matter the
security price goes up or down. This strategy is established by
buying near the money call and put option at the same strike
price. The disadvantage of this strategy is the high breakeven
level. The sum of the call and put option ask price is the
breakeven level of this strategy.
You only generate profit when the security price has gone up
or down more than the breakeven level. If the security price
fluctuates within the upside and downside breakeven level, you
still loss money. The money that you loss is due to the
depreciation of the option time value. This strategy is usually
applied for the security, which has high volatility or before
the release of the earning report. The maximum loss of this
strategy is the total amount of call and put option price. This
strategy can generate unlimited profit at either side of the
market direction
Strangle is quite similar to straddle. The
difference is strangle is established by buying out of the
money call and put option. Because both the options are out of
the money option, therefore, both options have different
strike. The maximum loss of this strategy is less than the
straddle strategy, but difference between the upside and
downside breakeven level is slightly higher than the straddle
strategy.
For this strategy, the upside breakeven is calculated by
adding the total call and put option prices to the call option
strike price. While, the downside breakeven level is calculated
by subtracting the put option strike price with the total call
and put option prices. The difference between the strike prices
usually is about 2.50 or 5 depending to which stock that you
select to buy with this strategy. If the security price
fluctuates within the upside and downside breakeven level, you
still loss the money due to the loss of the option time value.
Application of this strategy is the same as the straddle
strategy.
Covered call is established by buying a
security at the current market ask price and selling out of the
money call option. Selling out of the money option has limited
the profit that generated from this strategy. If security price
continuously goes down, it will cause an unlimited loss.
Therefore, stop loss must be set. When the option has comes to
its expiry, if the security price is not moving up
significantly, you still earn the total option premium that you
have received. If the security price goes up, sure you will
earn a limited profit. If the stock price continuously goes
down, it will cause an unlimited loss.
Therefore, stop loss must be set. Usually, stop loss is set
at the security ask price after subtracting by the option bid
price. If this security price goes down and passes over the
price that you set as stop loss, the loss that is incurred to
you is about half of the total option premium that you have
received. This is because the delta value of the out of the
money call option that you have sold is about 0.4 - 0.5. The
out of the money call option strike price must be the closest
strike price to the entering security price.
Collar is also known as medium covered
call. It is quite similar to covered call strategy. It is only
added one more step in order that stop loss is unnecessary to
be set in this strategy. This strategy is established by buying
a security and near the money put option and following selling
an out of the money option. Due to the put option that you have
bought, it is unnecessary to set a stop loss because put option
will protect the security if the security price goes down.
However, out of the money option premium that you have
collected has to be used to pay for the put option premium. If
the security price goes down, you still loss about half of the
total put option premium. This is because out of the money call
option premium is less than the near the money put option
premium. This strategy is for half or one year long term
investment.
Condor strategy has four combinations. Two
of them are for stationary market and the other two are for
dynamic (volatile) market. Long call and put condor are for
stationary market whereas short call and put condor are for
dynamic market. The former strategy involves four steps that
are buying and selling in the money and out of the money call
option with an equivalent amount of contract. With this
strategy, profit can be generated as long as the security price
does not fluctuate out from the upside and downside breakeven
level. Short call and put condor are for dynamic market, which
also involves four steps like the long call and put condor
strategy.
The difference is that in short call and put condor, the
strike prices of the options that have bought must be within
the strike prices of the options that have sold. For short call
and put condor strategy, profit can be generated as long as the
security price has fluctuated out of the upside and downside
breakeven level. The upside breakeven level is calculated by
adding the whole position total pay out or receive to the
highest strike price in the strategy. The downside breakeven
level is calculated by subtracting the whole position total pay
or receive to the lowest strike price in the strategy.
Combo strategy has two combinations that
are bullish and bearish combo. Bullish combo strategy is for
bullish market and the bearish combo strategy is for bearish
market. This strategy involves two steps that are buying out of
the money option and selling in the money option. If the
security price goes up more than the higher strike price,
profit can be generated. But if the security price goes down
lower than the lower strike price, loss is incurred. If the
security price fluctuates within the higher and lower strike
price, you won’t loss anything. This strategy can earn an
unlimited profit but also will cause an unlimited loss
depending to the market direction and also which strategy you
have used.
Butterfly spread strategy is quite similar
to the condor strategy. It has also four combinations that are
long at the money call and put butterfly spread and short at
the money call and put butterfly spread. Long at the money call
and put butterfly spread are for stationary market and short at
the money call and put butterfly spread are for volatile
market. Steps that involve in long at the money call butterfly
spread are buying in the money and out of the money call option
and following selling at the money call option. At the money
option means the strike price of this option is quite close to
the current market security price. Number of contract of the at
the money call option must double the number of contract of in
and out of the money option.
Profit can be generated as long as the security price does
not move out from the upside and downside breakeven range. The
upside breakeven level is calculated by adding the total pay
out of this position to the highest strike price. The downside
breakeven level is calculated by subtracting the lowest strike
price with the total pay out of this position. The short at the
money call butterfly spread is established by selling in and
out of the money call option and following by buying at the
money call option. Number of contract of at the money option
must be double the number of contract of in and out of the
money option. As long as the security price has move out the
upside and downside breakeven range, profit can be generated.
This strategy generates limited profit and also cause limited
loss if the security price does not go to the right
direction.
Calendar spread is also known as horizontal
or time spread. This strategy is solely used to earn money from
the security, which price trades sideway. There are quite
number of stocks have this kind of price trend. This strategy
is established by selling at the money call or put option,
which has a shorter time to expiry and buying at the money call
and put option, which has a longer time to expiry. This
strategy merely generates the money from the time value of the
option. The option that has shorter time to expiry depreciates
the time value faster than the option that has longer time to
expiry. Usually, the option that has shorter time to expiry is
left for expire worthless. The total money that you receive
after closing this position will be more than the total money
that you have paid out when opening this position.
With these ten strategies, you can use to earn money from
upside and downside market and also the market that trades
sideway.
