For years, DINK couples were told that the smartest financial move was simple: buy an index fund, automate your contributions, and never touch your portfolio again. That advice worked beautifully in the 2010–2020 era of low inflation, low volatility, and predictable market growth. But 2026 is a different world—one where inflation, interest‑rate whiplash, geopolitical shocks, and sector concentration have changed the rules.
The old “set it and forget it” mantra is now leaving many investors underperforming, overexposed, and dangerously unaware of the risks hiding inside their portfolios. If you’re a DINK couple trying to build wealth efficiently, it’s time to rethink how hands‑off your index fund strategy should really be.
