When you anticipate that a stock (or
index) will undergo a bullish or bearish price change, there are several (very
basic), limited-risk, option strategies that you can adopt. These involve
buying option premium.
·
Buy calls or call spreads when
bullish.
·
Buy puts or put spreads when
bearish.
The
more experienced trader may also want to consider selling option premium in
order to collect time decay (Theta is
one of the Greeks that
helps traders measure and manage risk).
·
Sell call spreads when bearish.
·
Sell put spreads when bullish.
·
Sell naked
(cash secured) puts when bullish -- but only when
you are willing to own shares of the underlying stock.
NOTE:
The more sophisticated reader knows that buying a call spread and selling a put
spread are equivalent positions (with
essentially identical profit and loss parameters) when the underlying asset,
strike prices, and expiration are identical.
Likewise, selling a call spread and
buying a put spread are equivalent positions.
Selling naked (unhedged) call
options is considered to be too risky for most investors for two very sound
reasons:
1.
The sum at risk is theoretically
unlimited, and too many inexperienced investors destroy their trading accounts
when adopting this strategy. Thus, very few brokers allow their inexperienced
traders to sell naked call options. It is just as easy to go broke when selling
naked put options, even though most brokers allow their customers to adopt this
strategy.
2.
Careful, skilled risk management is
mandatory. It is very difficult for the novice trader to realize how unprepared
he/she is to handle the risk associated with being naked short call options as
the price of the underlying asset rises day after day.
Advice: If selling naked options is
attractive to you (I shudder), please be certain that you sell an appropriate
quantity of option contracts. Unexpected market events occur far more often
than statistics predict -- and you must never own a position so large that it
can jeopardize your entire brokerage account when one of those events does
occur.
