Value of Leverage in Options
Trading
Why do options offer any advantage over trading stocks?
They're riskier, since they expire within a certain amount of
time and their values are more complicated to assess.
Since they expire the investor has to make a choice within a
relatively short time frame. (Even LEAPs - Long-term Equity
AnticiPation Securities - are generally written for no more
than two years.)
Since, as derivatives, they have no inherent worth they can
move in sharply different directions from the underlying asset.
One can short a stock or go long, but once bought the value of
the shares is known. Even after you purchase options, their
value is often solely 'time value', they're worth money only
because some event may occur in the future, such as a rise in
the price of the asset.
Nevertheless, options are actively traded in large volumes.
What do options traders know that many investors have yet to
learn? One thing they know is the value of leverage.
Imagine a small child in a children's playground. A small
child can lift an adult into the air, provided the pivot point
under the horizontal plank is placed appropriately. That force
'multiplier effect' has an analogy in financial markets.
For generally around 5% of the price of the underlying asset
an investor can control - even though they do not own - 100% of
a quantity of stock.
Suppose MSFT (Microsoft) is trading at $28 on a given day. A
trader who anticipates that the price will rise can purchase
one options call contract which confers the right to buy 100
shares.
That call option, with say an expiration date in three
months time with a strike price of $30, will cost somewhere
around $3. (The 'strike price' is the pre-set price at which
the shares have to be bought if the option is exercised.)
If the shares were purchased outright, even at the lower $28
price, the investment would cost $28 x 100 shares = $2,800
(plus commission). Buying a call instead costs $3 x 100 shares
= $300 (plus commission). That ratio, $2800/$300 = 9.33 is the
'multiplier effect' known as leverage.
Conversely, you could invest the same $2,800 dollars by
simply buying more contracts to control more shares. That's
another form of leverage. Controlling more shares for the same
money is equivalent to controlling the same shares for less
money.
How is this an advantage?
The answer is that, though the investor takes on the risk of
losing the premium (the cost of the contract), that multiplier
effect operates on profits as it does on costs. Since the
investor controls more shares, profits are potentially
higher.
Suppose MSFT rises above the strike price ($30) to $35. If
you purchased the shares directly at $28 per share, with $300
to invest, you could only purchase 10 shares. (10.7 if you have
a plan that allows fractional share investing, but part of that
will go for a commission.)
Your profit on the trade would be (ignoring commissions) 10
x ($35 - $28) = $70. If instead you had purchased an option on
100 shares, your profit would be (($35 - $30) - $3) x 100) =
$200.
You had to pay more per share, and the premium reduced your
profits, but you controlled many more shares. The net is still
considerably higher.
Keep in mind, though, that it works on losses the same way.
If MSFT had fallen in price, but you were obligated to a strike
price of $30, exercising the option would cost you by that same
factor. Under those circumstances, traders simply let the
option 'expire worthless', limiting the loss to the amount of
the premium.
The multiplier effect - leverage - is one major factor in
the value of options.
