Now would be the time to sell Apple.
Others have reached comparative standings as Apple has today, but its annual stock value appreciation has likely reached or is reaching a plateau. Yes, it is still a “hold” but should less often be a “buy” if total portfolio appreciation for the next decade or longer is sought.
The new iPhone is about to roll out, the economy is growing and we are going to be back in the holidays soon. I would say buy.
Perhaps, however that same advise has been issued many times in the past for variety of reason including hitting all time highs. AAPL pays a hefty dividend and is worth hanging onto for just that reason.
