Key Points
-
Nvidia should remain the top name in artificial intelligence chips, but its continued dominance of this market is in question.
-
Tesla is moving into what could be a big AI android market, but investors may be underestimating the competition on this front.
-
Apple shares have soared since early 2023 for good reason, but now are arguably fully valued. They may even be overvalued.
Technology giants Nvidia (NASDAQ: NVDA), Tesla (NASDAQ: TSLA), and Apple (NASDAQ: AAPL) remain the most actively traded tickers globally, with market sentiment overwhelmingly bullish. However, I am increasingly leaning toward a bearish stance on all three. Here is the rationale for each.
Nvidia
Nvidia undoubtedly maintains its position as the leader in the artificial intelligence processing chip market, having sold $89 billion worth of data center silicon in the last quarter alone, representing a 117% year-over-year increase.
However, the landscape for high-performance processors is shifting. While graphics processing units (GPUs), such as those manufactured by Nvidia, still form the backbone of most newly constructed AI platforms, alternatives are rapidly gaining traction. This includes conventional central processing units (CPUs) from players like Intel, but the next phase of AI technology will also prominently feature chips such as Alphabet‘s Tensor Processing Units and Amazon‘s Graviton processors.
Both were engineered from the ground up as alternatives to Nvidia’s costly hardware. More critically, they were designed to serve the customers of the world’s two largest public cloud computing service providers.

This does not mean Nvidia is doomed; its GPU-based solutions will remain a viable market option. However, with the stock priced on the assumption that the company will grow its top line by 84% this year and another 44% next year, there is zero room for error if the AI industry begins adopting these alternatives more frequently.
Given that poor returns on investment continue to plague many institutions embracing AI, I suspect many of these organizations are already exploring alternative platforms—the last thing the current market leader wants to see happen.
Tesla
The buzz surrounding Tesla’s AI robotics endeavors remains palpable. CEO Elon Musk stated earlier this year that the electric vehicle company could be mass-manufacturing and selling its humanoid assistants by the end of 2027, and he has not extended this commercialization timeline since.
Given Musk’s suggestion that these AI androids—called Optimus—could become “the biggest product ever made” and eventually account for the vast majority of Tesla’s market value, it is understandable that investors are watching this stock closely.
However, the crowd is not exactly plowing into the stock in droves. After a solid but erratic gain between 2023 and 2025, the stock is now down nearly 30% from its December peak.
Investors are likely mindful of Musk’s tendency to overpromise and underdeliver, particularly regarding timelines.
The very short timeline keeping Tesla’s price mostly buoyed is the problem. I do not believe most investors fully appreciate how many other technology companies are developing their own AI-driven humanoid robots. These companies could bring their products to the commercial market before Optimus becomes widely available, even though it has already technically entered production at Tesla’s Fremont facility.
An OpenAI-funded company called 1X Technologies is developing a humanoid robot named NEO, while Figure AI’s “03” model shows tremendous promise as an at-home assistant. Unitree, Apptronik, Neura Robotics, and AgiBot are among the other names nearing readiness to enter the humanoid robot market.
This is a prospective problem simply because much of Tesla’s current stock value is based on the assumption that its android assistant will actually start being sold en masse by the end of next year, which is highly uncertain.
Apple
Finally, I am adding Apple to the list of stocks that almost everybody seems to love right now, except me. This is particularly true given that the stock is still within reach of the record high it hit in late July following its 150% rally since the end of 2022.
To its credit, Apple regrouped well enough following its disappointing foray into the artificial intelligence era in late 2024. New features have been added and older ones improved. Most noteworthy perhaps: its digital assistant Siri works as well as it arguably should, given the company’s once-stellar reputation.
Consumers are responding as well. After a slow patch, Apple’s iPhone revenue improved by 22% during the quarter ending in June, and is up just as much through the first three quarters of the fiscal year ending in September.
Just keep your expectations in check—I certainly am. Not only is AAPL stock almost fully valued at less than 4% below analysts’ current consensus price target of $333.10, but the company also has a new CEO—the second since Steve Jobs left the role.
While John Ternus is certainly capable enough, each chief executive following the bigger-than-life visionary who transformed Apple into the powerhouse it is today operates at an increasing disadvantage. The company no longer has as much opportunity to create and cultivate new consumer-technology profit centers as it used to, and competitors continue to figure out how to keep Apple in check.
For example, rather than limiting its users to a home-grown artificial intelligence solution, Apple’s Siri is now powered by Google’s Gemini, while OpenAI’s ChatGPT is readily accessible through iOS’s Apple Intelligence.
The long-standing, impenetrable developmental silo that gave Apple its competitive edge is slowly fading away. For now, the stock is still being priced as if it hasn’t.
