Chart: Apple's wild weekendApril 29, 2013: 12:10 PM ET
Some strange doings in Apple's share price while the markets were asleep.
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.
