ETF Zoo: What Happens When Tech Eats the Entire Market?

Article excerpt

The technology sector's dominance in the stock market has reached historic proportions, with major indexes now heavily weighted toward a handful of mega-cap tech firms. This concentration raises questions about portfolio diversification and market vulnerability: if a tech downturn hits, broad-based ETFs designed to track the overall market will suffer disproportionately. The article examines how passive investing through index-tracking ETFs has inadvertently amplified tech's influence, creating a feedback loop where rising tech stocks attract more ETF inflows. Investors seeking genuine diversification face a dilemma, traditional broad-market funds no longer provide it.
