Apple's stock price drop in the closing minutes of trading on April 29th

Fortune reports on an interesting phenomenon being observed in Apple's stock price related to the weekly options market, the trading of rights to purchase stock at a given price at the end of a specified period. According to the report, Apple's stock is consistently seeing suspicious price changes on Fridays as those options are set to expire, activity that makes a significant of traders lose any potential gains as the stock price moves to meet the strike price for that week's options. In many cases, that activity serves to depress the overall stock price, thereby also negatively impacting regular traders as well.
It was 3:48 p.m. on Friday April 29 and traders who had purchased Apple (AAPL) April 29 $350 "calls" -- options that gave them the right to buy Apple shares in blocks of 100 for $350 per share -- were sitting pretty. The stock was trading around $353.50 and those calls were worth more [than] $350 apiece (the difference between the price of the stock and the so-called "strike price" of the option times 100).

Then, in an extraordinary burst of trading -- exacerbated by the rebalancing of the NASDAQ-100 scheduled for the following Monday -- more than 15 million shares changed hands and the stock dropped below the $350 strike price just before the closing bell. Result: The value of those calls disappeared like a puff of smoke.
Fortune went back and charted the daily closing prices for Apple stock over the past eight weeks, comparing the Friday closes to the "max pain" price at which options on both sides of the equation (puts and calls) have the least value in aggregate. Throughout the time period, Apple's stock consistently moved toward the max pain point on each Friday, sometimes over a period of only minutes as trading came to a close for the week.

While the phenomenon is not new and not unique to Apple, the reasons for it are not entirely clear. Some have argued that normal hedging activity is responsible for the drifts in stock price, but scientific studies have shown that such stock price behavior would not be accounted for by simple hedging and is thus indicative of stock price manipulation, which is illegal under U.S. securities law.

Apple is obviously one of the most closely watched stocks these days, and with the second-largest market capitalization in the U.S. markets has the potential to significantly influence trading. And so an apparently consistent manipulation of Apple's stock price makes for an interesting story, even if it is not yet clear who is responsible for the activity and how it is being accomplished.

Second, the author mentions the NASDAQ rebalancing, but only in passing. In reality, there were tens of millions of Apple shares (perhaps scores of millions) that needed to be sold by indexed funds in order to match the rebalancing that took place the very next session!! (2 May) This alone would fully explain the behavior of the stock price. Managers saw that the price was strong during the day, so they waited for the last minute to dump what they had no choice but to do.
 
... other commentators noted that the image was cherry-picked to prove a point... it seems to be yet another article that's going off half-cocked to get cheap views.
 
Wait a minute so you're telling me those really high speed servers owned by private financial companies who are conveniently colocated in same data center as the NYSE ARE being used to game the system? who woulda thunk!?
 
Sounds like some leet haxors doin some leet things. :rolleyes:
I hope they figure it out though... if the values drop that much that fast...
 
Not the Options thing. Not again... :rolleyes:

Oh, Apple, learn how to play nicely in the Stock Market.

What are you talking about? If you didn't read the article why comment?

It's about stock traders manipulating the market. Not Apple "playing nicely."
 
This is actually VERY common.

Google the term "pinning a strike price" and you will find various explanations of this activity. It is also sometimes called "pegging a strike price". To be clear, this is a market phenomenon, nothing to do with the boys in Cupertino.

The market manipulating dirtbags in the minute-by-minute trading game make it difficult for those of us investing the old-fashioned (honest) way. :mad:
 
This is pretty nonsensical. Fortune should know better. This is a natural phenomena of option pricing. Of COURSE the market is going to drive the stock to the price where the maximum number of options will expire worthless.

Traders (as opposed to those using options for legitimate hedging reasons) don't want to hold options to expiration. If a near-the-money call option is looking like it is going to expire with a value of, say, $1, then the holder of those options is going to sell them. Ultimately, they are going to be involved in a conversion, where the buyer exercises the call (acquiring the stock at the fixed, option price) and then immediately sells the stock. Of course this sale is going to help depress the stock price.

Expiring puts that are in the money are going to help force the stock price up.

The two opposing forces will try to force the stock price to the "max pain" price, which will depend of the overall balance of open calls/puts.

The only fix that I can think of is continuous expiration, rather than a fixed weekly expiration day. Wasn't aware that options went to weekly expiration, and assume that this was meant as a move toward continuous expiration which perhaps back-fired, because it now creates the phenomena weekly rather than monthly.

It's normal *trading* activity, not normal *hedging* activity that is going to force the price to max pain. Hedgers hold options to expiration. Traders don't. The extent to which max pain comes into play will in part be determined by how many options are held by traders as opposed to hedgers.

Same here... I hang onto stocks for years. A good investment in a solid company will survive the ups and downs in the long run.
Unfortunately the old dot com style of day trading never fully died.
Day traders with good cash reserves can make the market have a heart attack if they touch the right stock(s).
The hard part is finding the right stock at the right time.
Looks like someone figured out AAPL's cycle and decided to have some fun with it.

Actually this sort of game only affects those who are doing the short-term investments and playing games with various stock derivatives like options and futures. This sort of fluctuation has no effect on the long term investor. Maybe you were referring to the guys buying the options and complaining about the price drop as the dirtbags. Sorry if I misread.

If you are holding for the long-term, this this has no impact on you.

Spread out your buys/sells over time (which is a good idea for the long-term investor, anyway) or if you MUST buy sell a large block in one day, use a VWAP trade.
 
I've been a stock investor in AAPL since early 2007 and I can tell you that from my vantage point there has been some rather strange activity for the past six months that seems to be based on the options market.

To whomever above is basically saying "this is how options markets work" you are ignoring that there is an effect on the "normal" workings of the regular market. AAPL shouldn't close every Friday at the specific numbers it's closing at, except for the options pricing. Personally, I'd like to see all options go away. Either buy the stock or don't.
