Heaven? Whatever gave you the idea that you were in heaven, Mr. Valentine? This IS 'the other place!!There's a famous episode of the Twilight Zone (A Nice Place To Visit, season 1, episode 28) in which a gambler, who thinks he has died and gone to heaven, walks into a casino and can't lose. Every time he plays a hand of blackjack he's a winner, every time he pulls the handle on the slots he hits the jackpot and every time he plays roulette the ball lands on his number.
Now imagine that you walk into the Twilight Zone Casino and put a Benjamin on number 19, say, on the roulette wheel and the ball lands on 22. You feel a momentary pang of loss for having played a sucker's game, maybe even a little duped by having watched too much late-night TV .... but then the Twilight Zone Casino croupier offers you a deal: "I'll give you your Benjamin back from the previous spin plus an extra buck or two for your trouble if you play your number again."
Madness, no!? Never happen, right!?
Well, this very deal plays out every week in options trading and its why I'm changing my trading style. The analogous transaction to the Twilight Zone croupier's deal is called a calendar roll. In a calendar roll you buy back the near term short option and sell a longer term option at the same strike price, in a single transaction. Due to the fact of option pricing, in which options with more time are more highly valued, this roll transaction is certain to generate a credit (well, almost certain)* - no matter how badly the position has gone against you prior to expiration. Moreover, you can perpetually roll that loser short option to generate a credit every cycle.
To be eligible for this Twilight Zone Roll you must enter your position by short selling or "writing" an option. You can sell a put option or a call option or both even, it doesn't much matter. Then you wait.
There are four possible outcomes, three of which can always be handled positively and the fourth almost always positively:
- Your short option is out of the money at expiration. You buy back your short option for pennies on the dollar, you win the maximum gain.
- Your short option is slightly in the money at expiration but worth less than what you sold it for. You buy back your option for a relatively modest gain, you win.
- Your short option is deep-in-the money at expiration and is worth a lot more than what you sold it for. You buy back your option and sell next months option at the same strike price for even more money, you win. This is the Twilight Zone Roll. You were losing but you still win.
- Your option is exercised early and you now have an equity position. This is low probability and I will address this at length below but can be handled analogously to #3 - immediately close the equity position put to you and sell the same option option again -or- the same option in the next expiration cycle. I will argue that this almost always results in the same positive outcome as #3. You still win.
Even knowing this, it has taken me some years of option trading experience to really be convinced that this TZR "out" can't be magically taken away at expiration like Lucy holding the football for Linus to kick. This is because when a short option position is running against you, its just unnerving to eyeball the red ink. One must resist the temptation to pre-empt the trade by closing it out and walking away. Hold it and roll it. Then roll it, til you make it.
As for the early exercise scenario, #4, the incentives for the option owner are against early exercise. This is because the exerciser of an option is foregoing the time-value of the option that he would have gained by simply selling the option. Furthermore, the time value of the cash obtained by exercising a put is almost nil these days because of the low interest rate environment we are in (least to mention you give up 3 days of interest clearing the trade.) The possible exception to this observation is for a dividend paying stock. A call option owner might decide to exercise on the last day of the dividend period (1 trading day prior to the ex-div date) in order to capture a dividend payment. Even still, said dividend must be larger than the time-value on the option (+trading fees) to make the exercise a profitable proposition. However, it is not difficult for the option obligee to evaluate this and roll early.
On the other side of the exercise, the option obligee gains this time-value in the event of an exercise because the contract ended early without him having to pay-up the time value that he would have otherwise had to pay to be released early from the contract. This time-value at the time of exercise provides monetary leeway for the obligee to dispose of the equity position, if desired. Immediately selling the same month's or next month's option will realize this time-value back to your account.
Now, the only real gotcha in this strategy is a total Lehman-like crash and burn, where a respectable $50 stock suddenly and permanently stops trading over the weekend. In the case of Lehman, put obligees that were not exercised, would not have been able to roll perpetually because the option makers stopped creating new options for Lehman. While this is an ever-present risk for the premium seller, it is never-the-less extremely rare. For this reason, and other motivations, I do engage in protective option buying in a strategy called a diagonal that would limit the downside of such an adverse event. However, the existance of a reliable Twilight Zone Roll has redirected my trading focus. This is a fact-based strategy so I know I am not in that other place.
*Since I wrote this blog entry I have actually encountered a situation where I was quoted a small debit on a calendar roll. I believe this to be the work of dividends. In the particular case, the roll to the nearest next weekly option on SPY from SEP4 to SEP5 on the 134 strike puts was quoted as a debit of 5 cents or so. This time period spanned the ex-dividend date of SPY. However, I was able to roll to the OCT monthly expiration for a credit.
