Time Decay and Holiday Trading

Posted by Pete Stolcers on May 30, 2006

In today’s option trading blog I will discuss why Exchange Holidays need to be factored into your trading plan. If you were considering a trade a few weeks ago, the Memorial Day weekend should have been taken into account. There is a pattern ( it’s more pronounced from April – Sept.) that encompasses extended weekends. The prior week will include a day or two where most of the activity takes place. As the weekend draws near, the volume subsides. If you’re a premium buyer, know that a thief will be at work. If you’re a seller, know that the risk level may be elevated.

Let’s look at the next major holiday – Independence Day. July 4th falls on a Tuesday this year. That means that Monday will be a non-event since most traders will make it a 4-day weekend. Here’s how the last week of June is likely to shape up. Monday, Tuesday or Wednesday will contain one or two nice trading days with good movement and activity. Thursday afternoon, holiday fever will begin spreading. Traders will be more focused on their Friday Tee-times than the market. Those who show up Friday will work the first few hours. If all is quiet, they’ll get a jump on the traffic and leave early. Experience has taught them that there is little money to be made. In fact, the action can be whippy and unpredictable. Why waste a nice day and run the risk of losing money? On the backside, there’s a good chance Wednesday (July 5th) will be quiet as well. Traders will be trying to get their bearings and some will still be on vacation. Including this “holiday hangover”, premium buyers have been stripped of a week’s worth of “action”

This year’s Memorial Day weekend was atypical. There was a good move Friday and a nice move today (Tuesday). Normally the pre-holiday activity is more subdued with a tighter range. I attribute the movement to the sharp 5% pullback that started a few weeks ago. The market is currently in a state of flux, hence the larger than normal moves. This price action does illustrate another point. Exaggerated moves can take place during light volume days because there are less traders to stand in the way. The net affect of both days (Friday and Tuesday) is marginal. Be aware of any economic news that may be released during the pre/post holiday trading sessions as you form your plan. They may also have an elevated affect on the market.

Am I telling you to sell premium during this period? No, often some of the “juice” has already been taken out in anticipation of the calm. Chances are you won’t be selling “rich” premiums the week before. With lighter trading activity, a small news event or a large order can drive the stock. Your risk might actually increase without the corresponding reward.

Am I telling you to buy premium? No, realize that premium decay and the passage of time will be working against you.

The lesson is to be cognisant of the event and to account for it in your plan. If you were planning to buy July options now, you may want to buy the next month out (Aug) knowing that your trade may need more time to “work”. If you are short options, you might want to plan on buying some in just before the holiday if the premiums have already dropped. If you are initiating a trade at the end of June, your plan might reduce the size of the position.

I have found that price movements in active markets with “full participation” have substance and are much more reliable. My job as a trader is to predict and my performance increases when the conditions are right. Consequently, I tend to reduce my exposure going into holidays. I can fully enjoy my time off and when I return, this approach helps me resume with a clear perspective.

    i am short some in the money puts (or calls) at expiration. what are the odds that i will be assigned? is there a place to go to get that kind of information? i’m assuming that it is not a 100% probability that i get assigned.

    If the options are $.05 or more in the money, they will be auto-exercised. If you are short ITM options, you have run the risk of assignment throughout the trade and you are prepared to take a position in the underlying. However, the real surprise comes to traders that are long ITM options. They will be exercised and they will come in long stock if they were long calls. That could pose serious overnight risk.

    If the options are more than $.05 in the money at expiration, you will be assigned. Monitor trades and close them out if they are close to the strike and you do not want to take the risk of holding the underlying.

    How would you handle this trade.  Sold Jan 2011 call leaps with a 5 strike price on a stock and brought the stock at 2.  If she hits the strike with 15 months to go and there is a 1.5 premium on 5 strike calls and it doesn’t get called.. is there anyway to lock in profits without selling the stock and going naked on the call leap?  I figure it would be called if it went up to 6.5.. but if she bumps up to 5 and then comes back down.. I want to lock in some profits without risk.

    Simply unwind the trade to take profits. Sell the stock and buy back the LEAPS. That is the only way to lock in profits. Buying protective puts or any other adjustment simply complicates the trade.

    Hi Pete,

    I am a beginner at options trading and have been reading your website faithfully, gaining a ton of knowledge. One question about option expiration/exercise though. Does after hours quote affect whether an option is exercise? E.g. I sold a put for a stock at $400. At Friday(expiration day), the price closed at $405. In after hours trading, the price dropped to $398. Would the option be exercised?

    Thanks in advance for your advice.

    The Options Clearing Corp (OCC) has a 7:00 PM cutoff for brokerage firms. They must submitt the exercise notice before then. Most breokerage firms start the process hours earlier and their cuttoff is usually 30 minutes after the close. 

    A $400 stock will chop around after hours on no volume. Normal trading hours are more indicative of the true price and that is usually what traders will use. However, it is just a matter of whether or not they want to be long stock at the strike price.

    If you are short options that are close to the money on a $400 stock at expiration, you are playing with fire. This is not a wise move for a beginner. Be careful.

    Hello,

    Before what time should one sell an option on Friday in order to get theta decay during weekend. When is the theta decay for the weekend credited to your account.

    Thanks
    Jay
