1 Red Flag Apple Investors Can't Afford to Ignore

Apple (NASDAQ: AAPL) has been a pretty solid stock pick for 2026, rising nearly 25% so far. That outperforms many well-known artificial intelligence (AI) investments, including Nvidia (NASDAQ: NVDA).

However, I think there is a red flag that Apple investors cannot afford to ignore. If you choose to ignore it, the consequences could prove disastrous for your portfolio.

Apple's valuation has gotten out of control

Normally, a company's stock performance is tied to its business performance. However, other factors, such as how much an investor is willing to pay for a stock, also play a role. A stock's valuation multiple reflects how bullish or bearish the market is on the stock. Still, sometimes the stock and the business can become decoupled due to valuation discrepancies. I think Apple is dangerously close to crossing that line.

Over the past two decades, Apple has traded at over 40 times earnings three times. The first was in the mid-2000s, but that quickly came crashing down during the financial crisis. The second was in 2021, when Apple was benefiting significantly from consumers spending more on electronics due to COVID-19 lockdowns. The last time was at the end of 2025, and the valuation promptly crashed after that.

Apple looks set to cross that valuation threshold once again. Still, even though its growth rate has accelerated in recent quarters, it doesn't appear to be enough to justify its valuation. A price-to-earnings ratio of 40 is a very high price to pay for a stock, especially at a 16% growth rate. Compared to some of its peers, this looks incredibly expensive.

Currently, Apple is the second-largest company in the world, behind Nvidia. However, Nvidia trades at a much lower price despite growing at a much faster rate.

There are several other big tech stocks that would trade in the high-20s times earnings if one-time gains didn't skew their valuation metrics, and I think that's exactly where Apple should trade. There's nothing Apple is doing that makes it worth that much more than its peers, and the stock could correct to a reasonable valuation or stay flat while Apple grows into its high price tag.

Regardless of which one happens, Apple is a precarious stock to invest in, and I think there are far better options for your investment dollars out there.
