Vanguard Tech ETF Offers Big Exposure to AI-Driven Semiconductor Growth

The artificial intelligence (AI) boom has significantly increased the concentration of tech sector exposure in semiconductor and hardware companies within the S&P 500. As of August 31, tech stocks accounted for 37.9% of the Vanguard S&P 500 ETF (VOO), which mirrors the index's performance. This concentration is driven by the evolving demand for AI infrastructure, with semiconductor stocks making up 42% of the tech sector.

The Vanguard Information Technology ETF (VGT) offers a low-cost way to bet on sustained AI-driven growth. Six of the ten largest components in VGT are semiconductor stocks, Nvidia, Broadcom, Micron Technology, Advanced Micro Devices (AMD), Intel, and Lam Research, accounting for 32.4% of the ETF, compared to just 14.8% in VOO. These stocks have seen substantial growth, with Nvidia's market cap exceeding $5.5 trillion, and other companies like Broadcom, Micron, and AMD joining the trillion-dollar club.

Despite concerns about overvaluation, earnings growth supports higher semiconductor stock valuations. The Vanguard Tech ETF is up 34.8% year-to-date, while the S&P 500 has gained 12%. Since the start of 2023, the tech sector has surged 218.1%, with the S&P 500 doubling. Valuations remain reasonable, with Nvidia trading at 24.8 times forward earnings compared to 18.9 for the S&P 500.

The AI infrastructure build-out shows no signs of slowing, with major companies like Alphabet, Meta Platforms, and OpenAI driving demand. The Vanguard Tech ETF, with a mere 0.09% expense ratio, provides a simple way to get exposure to a basket of semiconductor stocks. For investors believing in the early stages of the AI infrastructure build-out, VGT is an excellent buy.
