## Summary

The piece argues that a growth ETF’s headline number of holdings can mask heavy concentration in a handful of AI‑focused tech giants. It points out that the Schwab U.S. Large‑Cap Growth ETF (SCHG) holds 197 stocks, yet its top ten make up about 51% of the fund and technology accounts for almost 50% of the portfolio. Nvidia alone is 10.83% of SCHG, Apple 8.93% and Microsoft 7.31%, while adding Amazon and Alphabet brings five companies to roughly 35% of the fund.

That same AI‑spending cycle underpins revenue for Nvidia, Micron, Vertiv, Equinix and Arista Networks, meaning many ETF constituents share the same economic driver.

## Key points

- SCHG’s top 10 holdings make up about 51% of the fund, with technology accounting for almost 50%.
- Nvidia alone accounts for 10.83% of SCHG and nearly 9% of QQQ, tying many other stocks to the same AI spend.

## Why it matters

Concentration on a few AI‑spending giants means a growth ETF’s performance hinges on a single capital‑expenditure cycle, exposing investors to outsized risk if those companies’ AI investments falter.
