Watch closely

NVDA · 34% largest29% broad ETF core

This portfolio needs closer review at 56/100. A 29% broad-market ETF core provides a useful foundation, but nVDA is 34% of the portfolio, creating single-position risk.

Cash review: 15% cash falls within the 0–20% reference range for growth over a long horizon; it may provide a useful reserve.

Diversification22/25

Strengths

Broad exposure reduces dependence on a small number of holdings.

Broad-market ETFs provide a meaningful core foundation.

15% cash falls within the 0–20% reference range for growth over a long horizon; it may provide a useful reserve.

The entered mix broadly fits a moderate risk profile.

Risks to monitor

NVDA concentration: 34%

Technology exposure: 56%

Treatment plan

Review NVDA first. Set a position-size ceiling and reduce concentration gradually if it no longer fits your plan.

Lower dependence on Technology by directing new contributions toward other sectors or a broad-market fund.

Recheck after your next contribution or allocation change and compare the score with this baseline.
