Bats are not blind, bulls do not rage at the color red, and the Great Wall of China cannot be seen from space. These myths persist, and a new misconception is emerging among investors: that all artificial intelligence (AI) stocks are overly expensive. While many AI stocks indeed command premium valuations, a deeper analysis reveals several affordable options worth considering.
For investors looking to allocate around $5,000 into AI stocks, three names stand out for their relatively low price-to-earnings-to-growth (PEG) ratios. First is Advanced Micro Devices (NASDAQ: AMD), which may initially appear costly with a forward P/E ratio of 39.7 and a staggering trailing P/E of 131.6. However, these metrics do not account for AMD’s substantial growth potential. The company boasts a PEG ratio of just 0.5, reflecting strong future earnings growth expected from its AI data center revenue, projected to grow at a compound annual growth rate (CAGR) exceeding 80% over the next three to five years.
AMD is increasingly capturing market share from Intel (NASDAQ: INTC) in the server CPU sector, while also gaining traction in the GPU landscape with its Instinct MI350 Series, marking the fastest ramping product in its history.
Next on the list is Micron Technology (NASDAQ: MU), a leading supplier of high-bandwidth memory (HBM). Contrary to the traditional view that memory chips are merely commodities, they are now seen as valuable assets due to the AI boom. Micron’s PEG ratio stands at just below 0.7, with shares trading at 12.3 times forward earnings. The company has secured contracts for its entire 2026 HBM supply and anticipates sustained demand, as CEO Sanjay Mehrotra highlighted during the fiscal 2026 first-quarter earnings call, emphasizing that strong industry demand coupled with supply constraints will maintain tight market conditions beyond 2026.
Recent forecasts from Micron suggest that the total addressable market for HBM could reach $100 billion by 2030, a target expected to be realized by 2028, representing a CAGR of approximately 40%.
The third notable stock is Nvidia (NASDAQ: NVDA), which has previously been criticized for its steep premium relative to intrinsic value. However, recent assessments, influenced by the company’s extraordinary growth prospects, have shifted this perspective. Nvidia’s PEG ratio is currently 0.7, as analysts expect robust growth over the next five years. CFO Colette Kress reiterated in the third-quarter earnings call that Nvidia anticipates annual AI infrastructure spending to reach between $3 trillion and $4 trillion by the end of the decade, a projection that gains credibility with emerging technologies like agentic AI.
Despite increasing competition from companies such as AMD and Broadcom (NASDAQ: AVGO), Nvidia’s prospects remain promising. Its Blackwell GPUs are recognized as the most powerful AI chips available, and the company plans to launch its advanced Rubin GPUs later this year. With substantial investments in research and development, Nvidia is well-positioned to maintain its lead in the AI chip sector.
However, prospective investors should take note: Nvidia was not featured among the stocks recommended by the Motley Fool’s Stock Advisor, indicating that other opportunities may offer even greater returns. Historical data shows that past recommendations, such as Netflix, which was recommended in December 2004, transformed a $1,000 investment into $450,256 by February 2026. Similarly, an investment in Nvidia recommended in April 2005 would have yielded $1,171,666.
With an average return of 942%, the Motley Fool’s Stock Advisor has consistently outperformed the S&P 500’s 196% return. Investors looking for the latest top stock picks may find value in joining the community built by individual investors for individual investors.
