iShares Core S&P 500 ETF vs. SPDR Portfolio S&P 500 ETF: One Offers Scale While the Other Boasts Lower Fees

A comparison of the iShares Core S&P 500 ETF (IVV) and SPDR Portfolio S&P 500 ETF (SPLG) reveals that both funds track the S&P 500 index, resulting in nearly identical performance, holdings, and sector exposure. The primary distinctions are SPLG's marginally lower expense ratio of 0.02% compared to IVV's 0.03%, and IVV's significantly larger Assets Under Management (AUM) of over $700 billion, which implies greater liquidity. While these differences are subtle, they could be relevant for investors with substantial capital or specific liquidity needs, though both offer similar broad market exposure.

Analysis

The analysis highlights a direct comparison between two prominent S&P 500 tracking Exchange Traded Funds (ETFs): iShares Core S&P 500 ETF (IVV) and SPDR Portfolio S&P 500 ETF (SPLG). Both funds demonstrate nearly identical investment results, including a 1-year return of 18.3% and a 5-year growth of $1,000 to approximately $2,092, reflecting their shared objective of mirroring the S&P 500 Index. Their underlying portfolios, sector exposures (e.g., 36% in technology), and top holdings like Nvidia, Apple, and Microsoft are also highly similar.

The primary differentiating factors are the expense ratio and Assets Under Management (AUM). SPLG offers a marginally lower expense ratio of 0.02% compared to IVV's 0.03%, representing a $1 annual difference per $10,000 invested. Conversely, IVV boasts a significantly larger AUM of $701.37 billion, dwarfing SPLG's $86.83 billion, which typically implies greater market liquidity and tighter bid-ask spreads for IVV.

Despite these operational distinctions, both ETFs maintain comparable risk profiles, evidenced by identical 5-year monthly betas of 1.00 and similar maximum drawdowns. For investors with substantial capital or specific liquidity requirements, these subtle differences could be material. However, for long-term, buy-and-hold strategies focused on broad market exposure, the impact of these variations may be less significant.

Key Decisions for Investors

• Investors prioritizing minimal costs should consider SPLG's 0.02% expense ratio, which offers a slight advantage over IVV's 0.03% and can lead to notable savings over extended periods, particularly for large portfolios.
• Institutional investors or those requiring high trading liquidity should favor IVV due to its substantially larger AUM of $701.37 billion, which generally correlates with enhanced market depth and tighter bid-ask spreads.
• Long-term investors focused on passive S&P 500 exposure can consider either IVV or SPLG, as their performance, underlying holdings, and risk characteristics are nearly identical, making the choice largely dependent on individual cost sensitivity or liquidity preferences.
