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.
I am not as down on Apple as you seem to think. I just rate it a hold - good value to keep if you got it, to have some stability in the portfolio (the way folks use to own AT&T and Exxon through many different economic cycles - good, strong to hold onto, if you got it).
But for money available to buy more stocks for the portfolio, I’m not looking for old reliable, I’m looking for what has - more than Apple I believe - greater % growth in its share price. I wouldn’t sell Apple and lose its dividend, but I wouldn’t buy more Apple with those dividends.
