Boris Schlossberg, a macro strategist with BK Asset Management, certainly thinks so, saying that "the best days of Apple are behind it."
It's not that Apple cannot grow, but that its innovation has stalled — and the company has to come up with a fantastic new product to push the market share to new levels.
He's also taking a hard look at the stock's enormous market capitalization. It's now the top-weighted component in the S&P 500, at a bit less than 4 percent of the index. "It's not a good sign to be the biggest in the S&P," he said Wednesday on CNBC's "Trading Nation."
"It means you've pretty much reached your apex as far as growth potential."
However, the mammoth size of the stock may not be particularly worrisome for investors when considering the superior weighting of another tech behemoth a little over 30 years ago — that of IBM, which was 6.4 percent of the S&P 500 at the end of 1985. That was back when John Sculley was running Apple, Ronald Reagan was running the U.S. and Paul Volcker was running the Federal Reserve. And since then, shares of IBM have gained more than 300 percent — albeit while significantly lagging the index.
Shares of Apple initially slipped after the company on Tuesday reported quarterly revenue that fell short of estimates; it also reported selling fewer iPhones than expected. Its cash hoard grew more than $10 billion from the previous quarter to reach $256.8 billion.
If Apple wants to grow further, it should pour money into its research and development, particularly if the company gets a tax break with repatriation under the Trump administration, said Max Wolff, 55 Capital market strategist. He said Apple may have significant room to grow in emerging markets and in augmented reality.
"I'm not so sure Apple is done growing in terms of its market cap or in terms of its weight," Wolff said Wednesday on "Trading Nation."
