Nvidia’s blockbuster earnings and CoreWeave’s 200%+ IPO surge have fueled a wave of excitement across the AI sector. Multi-billion-dollar valuations are now being assigned to companies that haven’t yet turned a profit. If this feels like déjà vu, it’s because it echoes the dot-com bubble era when hype drove valuations sky-high, only to collapse months later. Pets.com famously raised $82.5 million in its IPO before going bankrupt within a year.
While today’s AI market isn’t necessarily headed for the same fate, experts warn that we may already be deep into the hype cycle. The difference now is that some companies like Nvidia are generating real earnings and building infrastructure. But many others are riding momentum without fundamentals, making them vulnerable if sentiment shifts or spending slows.
Retail investors should stay alert. Before chasing the next AI ticker, evaluate cash flow, earnings quality, and valuation multiples. The next leg of the AI boom could be transformative but only for companies with staying power.
Veteran analyst Ted Mortonson sees echoes of the dot-com crash in today’s AI stock frenzy. While he acknowledges that this AI cycle is “more material and transformational,” he warns that retail investors may be falling into familiar traps chasing sky-high valuations on companies with little to no profits. “We’re looking at a red Dodge and calling it a Ferrari,” he quipped, pointing to speculative funding and inflated expectations. “This market is the casino.”
The S&P 500 is now trading at 22x forward earnings just below the 25x peak during the dot-com bubble but well above the 30-year average of 17. Meanwhile, AI favorites like Palantir (PLTR), Snowflake (SNOW), and CrowdStrike (CRWD) are trading at 265x, 190x, and 135x forward earnings, respectively. These extreme multiples don’t guarantee a crash, but they do raise the risk of sharp pullbacks if earnings disappoint or sentiment shifts.
Mortonson notes one key difference: unlike the 2000 bubble, today’s AI surge is backed by real cash flow from cloud giants like Microsoft and Google. Still, venture capital is aggressively funding early-stage, unprofitable startups many of which may not survive a downturn.
CFRA analyst Angelo Zino adds that while we may not be in a full-blown bubble yet, signs of euphoria are building. Since the April 2025 lows, the Nasdaq Composite has soared over 35%, signaling that the market may be overheating.
Retail investors chasing AI exposure should proceed with caution especially when dealing with companies that lack profitability. Analyst Ted Mortonson warns that many smaller AI firms are “brilliant on the technology side but ignorant on the financial side.” Without consistent cash flow or disciplined cost control, these companies are just one earnings miss away from a sharp correction.
Angelo Zino echoes the concern, emphasizing that investors should evaluate earnings quality and valuation against actual demand. “We’ve been going straight P/E for the most part,” he said. Nvidia (NVDA), for example, maintains strong earnings power because enterprise spending on computing remains aggressive year after year.
However, not all AI stocks share that strength. Zino cautions that some companies are being fueled more by speculative bookings and hype than by real profit or revenue. “Oftentimes, that’s a risky proposition,” he said especially in a market where sentiment can shift quickly.
To avoid the pitfalls of overhyped AI stocks, analysts recommend anchoring your portfolio with dominant tech leaders. Ted Mortonson advises investors to “own the cloud Titans and let it ride,” pointing to Microsoft (MSFT), Google (GOOGL), Meta (META), and Amazon (AMZN) as the backbone of AI infrastructure. These firms offer real cash flow, elite engineering talent, and long-term scalability.
The AI surge isn’t just smoke and mirrors at least not yet. Analysts widely agree that artificial intelligence has long-term staying power, but they also caution that the current hype cycle is running hot. For retail investors, chasing buzzy tickers without solid financials could lead to painful corrections. Instead, the focus should be on companies with strong free cash flow and consistent earnings.
The most reliable plays? Cloud infrastructure leaders like Microsoft, Google, Meta, and Amazon. These firms combine scale, profitability, and aggressive AI investment. As Ted Mortonson put it: “Lock in some gains. You’ve won.”
