FORTUNE -- Can anybody explain what happened to Apple (AAPL) between the close of trading Friday and Monday's opening bell?
I can almost wrap my mind around the 4.55 million shares traded at exactly 4:00 p.m. Friday and the temporary $3.08 drop one clock tick later. A bunch of Apple weekly options had just expired, and the market had a ton of trades to unwind.
But what's the significance of that $10.65 vertical spike to $429.20 at 4:00 a.m. Monday, when 1.4 million shares changed hands while the markets were asleep? Was it some kind of signal that only trading insiders -- or worse, computer algorithms -- can understand?
Note that by noon Monday, Apple's share price had topped $430, almost as if someone -- or some thing -- knew eight hours earlier that it was headed there.
Is there no limit to how much value Wall Street can take out of the stock?
FORTUNE -- In the fall of 2000, when you could buy Apple (AAPL) for $7, the stock's value measured by how much profit it was generating for each outstanding share -- the famous PE ratio -- hit an all-time low of 5.76, according to Wolfram Alpha (see chart below).
On Friday morning, when the stock touched MOREPhilip Elmer-DeWitt - Apr 19, 2013 8:27 AM ET
Waiting for Tim Cook to increase Apple's dividend yield? Today the market did it for you.
FORTUNE -- There is no shortage of theories why Apple (AAPL) -- already at a 453-day low Tuesday -- fell another $28.13 in mid-day trading Wednesday to touch $398.11, wiping out all of 2012's gains.
Among the reasons we've heard:

Two company valuations that passed in the night
FORTUNE -- Who would have guessed a week ago that the thing that would lift Apple (AAPL) out of its winter doldrums would be the unveiling of its fiercest competitor's whizzy new flagship device?
But that's what happened.
The day after Thursday evening's big event at Radio City Music Hall -- where Samsung introduced the Galaxy S4 in a faux-Broadway production that garnered mostly negative reviews MOREPhilip Elmer-DeWitt - Mar 18, 2013 4:10 PM ET
It's only in the past year that Samsung has (handily) outpaced Apple
FORTUNE: "Samsung's stock doesn't trade on US exchanges," writes the Bespoke Investment Group, "so hardly anyone here even looks at the stock."
Well, Bespoke did, and it produced the 10-year (above) and one-year chart (below). They show that over the long run, Apple (AAPL), as Bespoke put it, "crushed" Samsung.
Lately, however, not so much.

Even a long-time Apple naysayer like Henry Blodget is talking about buying the stock
FORTUNE -- In a 1,300-word Business Insider story in which he rattles off a litany of reasons why Apple's (AAPL) shares "crashed to a new low" Friday, Henry Blodget refers seven times to the stock price as "cheap," "cheaper" and "screamingly cheap" and ends by confessing that although he doesn't buy individual stocks these days, if the MOREPhilip Elmer-DeWitt - Mar 2, 2013 11:53 AM ET
The last time Apple traded below $430 was Jan. 24, 2012
FORTUNE -- The selling pressure on Apple (AAPL) continued unabated Friday, pushing the stock back to where it was 13 months ago.
Two minutes before the close of trading, Apple shares briefly touched 429.98. That's their lowest point since Jan. 24, 2012, when the stock closed at $420.50 in advance of the company's fiscal Q1 2012 earnings release. When Apple reported MOREPhilip Elmer-DeWitt - Mar 1, 2013 11:01 AM ET
Eleven lowered their 12-mos. targets in December, yet few stocks have as far to go
FORTUNE -- Analysts tend to get nervous when a stock they follow drifts too far from their published price target, and few stocks are as widely followed or as far out of whack as Apple (AAPL).
Eleven analysts lowered their Apple targets in the final weeks of the company's first fiscal quarter of 2013, which ends Saturday. MOREPhilip Elmer-DeWitt - Dec 28, 2012 8:37 AM ET
Which is more than you can say for most of Apple's competitors -- or the S&P 500
FORTUNE -- Despite the three-month-long drubbing that lopped $248 billion (26%) off Apple's market cap, its shares are still up 28.39% for the year.
In fact, many analysts believe those gains are the primary reason the stock fell from its all-time intraday high of $705.07 in late September to Christmas Eve's close of $520.17. Investors hoping MOREPhilip Elmer-DeWitt - Dec 24, 2012 2:05 PM ET

FORTUNE -- Of the two dueling Apple (AAPL) headlines Sunday -- 1) the news that Citigroup lowered its price target and downgraded the stock from Buy to Neutral, and 2) the news from Apple, released shortly afterward, that Chinese iPhone 5 sales set a record, topping 2 million in three days -- traders in Europe and Asia seem MOREPhilip Elmer-DeWitt - Dec 17, 2012 7:06 AM ET
