AAPL parabolic

Apple - bellwether stock - widely owned by individuals and funds, huge index weighting - so all index-linked funds have to be heavily invested - everyone knows it's a "great" company ;)..so what next?
Below is the quarterly chart, with a parabolic rise laid over the top.  "Parabolic up moves are exciting to ride, but there is the almost certain danger that the rocket will run out of fuel, resulting in a rapid collapse of prices. Trying to pick the final top for this kind of move could be hazardous to one's health, but being aware of the potential danger can be useful in managing positions."

Below the AAPL chart is the weekly silver chart which shows a parabolic move in 2011 and the subsequent collapse.  I'm not saying that the top is in AAPL - but care is needed.
