VerdictData-Driven

Only 14.1% overlap — these funds complement each other well for diversification.

VOO and ARKK represent fundamentally divergent investment philosophies, with VOO focusing on broad market exposure while ARKK targets disruptive innovation. The vast majority of holdings in each fund remain distinct, evidenced by a minimal 9.5% overlap between their top positions. While VOO is heavily weighted toward established technology giants like NVIDIA and Microsoft within its diversified portfolio, ARKK concentrates significantly more on specific high-growth names such as Tesla and CRISPR Therapeutics, reflecting its thematic approach rather than passive replication of the index. The operational structures of these funds yield starkly different cost profiles that influence net returns over time. VOO maintains a negligible expense ratio of 0.03% supported by substantial assets under management exceeding $1.5 trillion, ensuring highly efficient tracking with minimal drag on performance. Conversely, ARKK operates with an expense ratio of 0.75%, reflecting its active management style and smaller asset base of approximately $6.7 billion. This structural difference means investors in VOO incur significantly lower ongoing fees compared to those holding ARKK, a factor that becomes increasingly material as the investment horizon extends.
