what a statement
So I'm guessing you think Apples real value more than doubled in the past 2 years?
Based on what previously unknown information did the company gain around 400b in market cap?
The answer is simple.
Fools got burned when Apple got ahead of itself at over $700, and the same fools kept preaching not to buy when the valuation was cheap at $400. Now, those same fools think Apple should be at the equivalent of $1400+.
How efficient is a market where the worlds biggest company drops 50% and jumps 300-400% within the span of 2 years, when nothing has changed?
