Should You Buy the Invesco QQQ ETF With the Nasdaq at a Record High? History Offers a Clear Answer.

The piece examines the Nasdaq-100 (US Tech 100) and whether the Invesco QQQ ETF remains a buy at record highs. It notes the index’s heavy tech and AI exposure — tech now represents over 60% of the index — driven by mega-cap names like Nvidia, Apple, Alphabet, Microsoft and Micron. That concentration has powered outsized returns (Nasdaq-100 +177% since early 2023), but raises risk of sharp reversals if AI enthusiasm cools. The author argues QQQ remains a sensible long-term holding given its historical compound annual return (~10.6% over 27 years), but recommends diversification and dollar-cost averaging because some segments (e.g., Micron, up >900% in 12 months) show bubble-like behavior. Overall, the article is constructive on long-term prospects for the index/ETF while urging cautious, phased entry and portfolio balance to manage concentration risk.
