Don't buy Apple stock unless you like roller coaster rides. (The valuation is a screaming buy right now)
Apple stock has always been volatile; I owned Apple before the tech wreck of 1999. Bought @ $38
I woke up one morning to see my 'smart buy' a few days before has lost 40% of it's value in the low $20's. I sold and never got back in.... Of course in hindsight...
