It would be better to buy 10 shares now and take advantage of the surge in interest.
(technically a split doesn't change the underlying value of the stock since the value of a new share is exactly one seventh of the current value)
Investment decisions should not be made on news of a split unless you are a daytrader.
Apple's shares are going to be around $70 after the upcoming split and it seems as good a time as any to buy. I think it's pretty much guaranteed to go back up, maybe not all the way to $600 but even $200 would net me a nice return if I invest about $2000.
Thoughts?
