Are we in an AI bubble? Investors have been struggling with that question for more than two years. With AI-related stocks rallying like it’s 1999, comparisons to the days of “irrational exuberance” are everywhere.
If there is a bubble in the making, it’s important to determine where we might be on that late 1990s timeline. Is the year 2000 the appropriate analogy, which would imply a bubble is about to pop, or is it 1998, indicating that AI stocks still have room to run?
“I think we are closer to 1998 than 2000,” says Chris Buchbinder, equity portfolio manager.
As a former telecom analyst, he has experienced the dot-com euphoria. “It’s possible we will see an AI bubble at some point, but I don’t think we’re there yet.”
Today, stock prices for AI leaders are generally supported by solid earnings growth. What’s more, companies making aggressive AI-related investments — Alphabet, Amazon, Broadcom, Meta, Microsoft and NVIDIA, among others — can support their massive capital spending far better than the upstarts of the late 1990s.
“In my view,” Buchbinder adds, “it’s too early to let the risk of bubble trouble overcome the compelling opportunities presented by this formidable technology.”
5. There are always reasons not to invest
A pandemic, wars, inflation and high tariffs have sent shock waves through the global economy in recent years. For many investors, sitting on the sidelines as these events unfolded seemed like the most sensible response. Yet, time after time, financial markets pushed through turbulence and reached new highs.
Take the sweeping tariffs President Trump levied on nearly all major US trading partners in the spring of 2025. The S&P 500 Index plunged as much as 18.7% from its peak in February as investors feared the global economy would lurch toward a deep downturn. But trade deals and continued economic resilience helped calm those anxieties. By year’s end, the S&P 500 Index recovered and finished 2025 up 17.9%.
“Looking out over the next year, I’m both excited and uneasy,” says Chief Investment Officer Martin Romo.
“We’re living through a tech revolution driven by artificial intelligence, and the world is undergoing structural shifts in trade and the international order we’ve known for decades. But I’m reminded of what our past American Funds Distributors President and Chairman Graham Holloway said in 1981: ‘I have never known a good time to invest.’”
The lesson is not new: There have always been reasons to wait. It was true in 1981, 2020, and today. But markets have been resilient over time. History shows that investors who look beyond short-term uncertainty and remain committed to their long-term goals have often been rewarded.
