See what happened on Wednesday with Apple's stock. With no good cause
it looks like various parties started to try and short it. You can see
the initial result from 12pm->1pm, the 'quick buck' 1pm-1:30pm rise,
then the start of some more shorting at which point you can see the
pattern emerge where the automatic trading algorithms started doing
their thing. Definitely too volatile.
