Navigating AI Investments: Diversification and Valuation within the AI Theme


By Blake Heimann, Senior Associate, Quantitative Research and Christopher Gannatti, CFA, Global Head of Research

As Q2 earnings announcements approach, it’s crucial for investors to revisit growth expectations and re-evaluate concentration risk when considering exposure to the artificial intelligence (AI) theme. With the market breadth remaining quite narrow year-to-date, ensuring proper diversification and being mindful of valuations are key to building a well-rounded portfolio within the AI industry.

Avoid Concentration Risk

One standout performer in the AI industry is Nvidia, which experienced explosive price appreciation since the latest earnings announcement when they forecasted $11B in sales for the upcoming quarter—more than 50% higher than analyst expectations. Consequently, valuation metrics such as the price-to-sales ratio soared. If Nvidia seemed expensive six months ago, it has become an even more challenging “buy” to justify for value-oriented investors. Some may even question, is it “growth at a reasonable price” at this point?

However, relying heavily on Nvidia as an AI exposure can lead to concentration risk. Many investors seeking exposure to the AI megatrend opt for a broad tech approach—sometimes assuming an allocation to the Nasdaq 100 Index or the S&P 500 Information Technology sector suffices for AI theme coverage, resulting in mega-cap tech firms comprising a significant percentage of their portfolios. This concentrated and expensive approach may not be ideal for those looking to mitigate risk and diversify their investments while seeking to gain exposure to the AI theme. Luckily, there are other avenues to gain exposure to this exciting technology.

Consider Other AI Exposures

Companies like MongoDB and Elastic are creating vector search databases, enabling improved efficiencies in querying large language models (LLMs) like OpenAI’s ChatGPT to be used for inference. These innovations power various use cases—such as similarity search, recommendation engines, Q&A systems, dynamic personalization and long-term memory for language models—enabling businesses to harness proprietary data with LLMs to increase their efficiency.

Firms like Autodesk, with its computer-aided design software, stand to benefit from generative learning algorithms—which can be used to increase design efficiency by generating potential solutions tuned to the input parameters of the user. This allows the user to augment their creative abilities, using AI-generated outputs to streamline the process from idea generation to finished product.

At WisdomTree, we take an approach that covers various aspects of the AI value chain, seeking broad exposure to AI. This exposure can be broken down into subgroups such as AI Software, Semiconductors, Other Hardware and Innovation. By diversifying across these subgroups, investors can capture many different aspects of the AI theme. For example, gaining exposure to AI computing chips within the Semiconductor group, generative AI applications within the Software and Innovation groups, and autonomous vehicles and robotics in Other Hardware—allowing for a more comprehensive exposure to the breadth of the AI theme.

Be Mindful of Growth and Valuations

When seeking exposure to high-growth companies, valuation often comes at a cost. The significant run-up in prices of large-cap tech names at the beginning of the year has led to higher valuations and increased concentration within some of the broad market baskets. Through the fundamentally aware and diversified approach to the WisdomTree Artificial Intelligence & Innovation Index, the strategy seeks to blend strong forward-looking and historical growth with reasonable valuation statistics such as price-to-sales.

Breaking things down further on the growth side, it becomes evident that sales and earnings volatility persists in the AI industry, as demonstrated by Nvidia. When a large company like Nvidia forecasts a 50% growth in sales, the market reaction is significant, and the single stock impact on the broader portfolio can take effect—in terms of both allocation and aggregate statistics like growth rates. At the moment, for the holder, the price appreciation can be great, but as valuations steepen and another quarter nears, investors may anticipate impacts that the next earnings announcement may bring and question trimming the allocation to reduce risk. With each subsequent announcement, it becomes more and more challenging to give market participants a suitable “positive surprise” to keep pushing the share price even higher.

As you can see above, the WisdomTree Artificial Intelligence & Innovation Index growth profile is much more diversified than more concentrated alternatives. Those with large weights to mega-cap tech stars may show reasonable numbers but are much more reliant on these heavy allocations. The same can be said for their returns and volatility profile.

Investing in artificial intelligence requires a well-balanced portfolio that prioritizes diversification across the AI ecosystem. The WisdomTree Artificial Intelligence and Innovation Index provides a promising avenue for investors to tap into the potential of the AI industry while ensuring a balanced approach. By diversifying across different AI subgroups and adopting a strategy that emphasizes use cases as well as growth and valuation considerations, investors can effectively mitigate concentration risk while gaining exposure to artificial intelligence in a portfolio.
