Nvidia Valuation Debate Ignites Over AI Stock Rally

Nvidia's (NVDA) valuation is sparking a fresh debate about whether the artificial intelligence sector is overheated. DBS Group Chief Investment Officer Hou Wey Fook argues that the chipmaker's earnings growth and valuation make comparisons to the dot-com bubble difficult to justify. Nvidia currently trades at roughly 17 times its next 12 months of earnings, with profits projected to grow around 70% next year. Hou contrasts this with Cisco Systems during the dot-com boom, which traded at roughly 100 times earnings before the bubble burst.

Hou believes there are still strong tailwinds supporting the semiconductor and AI sectors. He recommends a barbell strategy for investors, combining growth-oriented technology exposure with investment-grade fixed income to manage risk. Gold and hedge funds are also seen as potential diversifiers.

The key question for Nvidia investors is whether earnings can continue rising fast enough to support the valuation. A 17-times forward multiple paired with projected 70% earnings growth looks less extreme. However, if growth expectations weaken, the argument against bubble-like valuations becomes less compelling. For now, Hou's point is that Nvidia's extraordinary growth may make the AI boom look expensive, but not necessarily irrational.
