AI and Memory Chip Rally Not a Bubble, But Future Returns Uncertain, Strategist Says

The powerful rally in artificial intelligence and memory chip stocks is underpinned by strong earnings growth, not just speculation, but investors should not expect recent high returns to continue indefinitely, according to a market strategist.

The surge in demand for AI-related hardware has shifted the leadership in emerging markets toward technology hubs in Taiwan and South Korea, raising questions about whether the sharp increase in company valuations is sustainable.

Earnings Underpin Rally

According to Andrew Dalrymple, Investment Director at Aubrey Capital Management, the key distinction from a classic speculative bubble lies in corporate earnings. "Earnings are growing fast on surging memory demand," Dalrymple said, noting that the current memory cycle appears more durable than previous ones.

Past booms were often tied to shorter-term PC, smartphone, and gaming hardware replacement cycles. In contrast, the build-out of AI infrastructure requires significantly more capital and longer lead times, making it more difficult for semiconductor supply to quickly meet demand.

Valuations and Signs of Froth

Despite the strong performance, Dalrymple noted that valuations for key players remain relatively modest. He pointed to major memory chip manufacturers as examples:

• Samsung Electronics trades at approximately six times this year’s projected earnings and four times next year's.
• SK Hynix trades on similar multiples.

However, Dalrymple also acknowledged "clear signs of excess," such as the emergence of leveraged ETFs tied to these specific stocks. This suggests that while fundamentals are solid, some speculative behavior is present in the market.

Outlook for Investors

While strong fundamentals support the sector, Dalrymple cautioned that this does not guarantee a continuation of recent performance. The primary challenge for market participants is to differentiate between sustainable growth and temporary momentum.

Ultimately, the next phase of the rally will depend on whether corporate earnings continue to grow at a pace that justifies the sector's significantly increased market weight, the strategist concluded.
