According to Mirae Asset Securities' analysis of its defined contribution and individual retirement plan accounts released this year, ETF investments across all age groups have surged to around 50% in 2026, up from 30-40% in 2024. The 40-year-old cohort led adoption at 60.4%, followed by those in their 50s (58.2%), 30s (57.7%), and 60s (50.4%), with younger and older investors also climbing to near 50%.
The composition of holdings has shifted markedly from bond-focused to equity-focused products. Where bond ETFs previously dominated retirement portfolios, investors across all age groups now favor U.S. equity index ETFs (S&P 500, Nasdaq 100), domestic semiconductor ETFs, and mixed equity-bond products. Notably, investors aged 70 and above selected a global AI-focused active ETF as their most-held product, signaling a willingness to maintain aggressive asset allocation beyond traditional retirement age.
