In order to understand the meaning of the term “historical
option price”, it is important to first explore what is meant by these
terms: “option” and “historical” in the context that the financial
market uses these terms.
The term “historical” – refers to over a specific period in the past.
The term “option” is a type of derivative, which means the value
depends on the value of the underlying investment. Investment in this
case could be a share of stock, index, currency, commodity or different
kinds of securities.
A stock option then is contract, between a buyer or holder and the
seller, known as the writer. The contract gives the owner a right
without any obligation, to buy or sell a particular stock at a fixed
price (the strike price) for a specific period of time (the expiration
date). When the owner or investor exercises the contract right, the
seller or the writer is obligated to meet the terms of delivering the
shares to the right party.
Trading in stock options is rather risky and can prove to be a
loss for the less experienced investors.
Some of its advantages are, an investor can gain leverage in a stock
without committing to a trade, and the option provides protection
against price fluctuations.
Some disadvantages – the cost of trading options is higher on
percentage basis than when trading the underlying stock, and reduces
the profits.
The time-sensitive nature of the option can render these options
valueless.
When the option availed of is the uncovered option kind, the investor
is exposed to unlimited risk.
Finally, in order to know what a “historical option price” is,
here are the three components of option:
The expiration date – shows the month in when the option expires and
this happens one day after the third Friday of the expiration month.
The strike price - The strike price is the price at which the holder is
allowed to buy or sell the underlying stock later date.
The premium – calculated as the amount the holder pays for the right to
exercise the option.
What are the factors that determine the value of an option? Well these
are the difference between the stock price and the strike price, the
remaining period the option can be exercised and the volatility of the
underlying stock.
As many unlucky investors have come to realize the value of an option
decreases the nearer the expiration date approaches and becomes useless
after that date.
One should remember that in general premiums increase as the volatility
of the underlying stock increases. This is because the greater
fluctuation makes the right to buy in the future at the current price
more valuable.
And volatility is either historical or implied.
It is historical when it is based on the based on the past performance
of the stock. It is implied volatility when it reflects the way options
are priced in general.
Knowing all the risks and disadvantages that come from exercising the
historical option price, should you risk it?
