Gotrade News - The Vanguard S&P 500 ETF crossed $1 trillion in assets. It became the second ETF ever to reach that mark.
The first to do so was the SPDR S&P 500 ETF. That long-running fund still holds the title of pioneer in this space.
Key Takeaways
- VOO crossed $1 trillion in assets, the second ETF to reach the milestone after SPY.
- VOO charges a 0.03% expense ratio, three times lower than SPY's 0.09%.
- VOO drew about $66 billion in 2026 inflows, well ahead of SPY's $36 billion.
The milestone reflects both index appreciation and steady new-share purchases. Investors keep adding capital to the fund month after month.
Cost is the main reason buyers favor VOO over rivals. According to The Motley Fool, the low expense ratio is the central draw.
VOO charges a 0.03% expense ratio against 0.09% for SPY. That gap means SPY costs three times more to hold each year.
The fee difference compounds meaningfully over long holding periods. For buy-and-hold investors, even small ratios shape net returns over time.
The trillion-dollar mark places VOO in rare company among funds. Only one rival had reached that scale before this moment.
Inflows Lead The Market
Through the first five months of 2026, VOO attracted about $66 billion in new capital. That figure topped every other ETF for inflows this year.
By comparison, the SPY fund pulled in about $36 billion over the same window. The contrast underscores how fee-conscious flows now favor the newer Vanguard product.
The two funds track the same underlying S&P 500 index. As reported by Quartz, the milestone came from both appreciation and fresh purchases.
Both VOO and SPY give investors broad exposure to large US companies. The choice between them often comes down to cost and trading needs.
Because the holdings are identical, performance gaps stay narrow over time. Fees and tracking remain the practical differences between the two funds.
Steady inflows can support a fund's scale and liquidity. Larger size often translates into tighter spreads for everyday traders.
The leadership in flows reflects a broader shift toward cheaper index products. Many investors now treat expense ratios as a primary screening filter.
Valuation And Concentration Risk
Investors should weigh the index's current valuation before buying. The S&P 500 trades at a price-to-earnings ratio near 27.4 times.
Technology stocks now make up about 35% of the index. That heavy weighting creates concentration risk for any S&P 500 fund.
A pullback in the largest technology names would ripple through both funds. The same index that powered the milestone also carries this exposure.
Neither fund offers protection against a broad market decline. Diversification within the index does not remove that single-market risk.
The elevated multiple leaves less room for valuation expansion. Future returns may lean more on earnings growth than on rerating.
For now, low costs continue to attract patient long-term buyers. The trillion-dollar threshold marks a notable step for passive index investing.
The milestone also signals how concentrated index funds have become. A few large names now drive much of the broad market's direction.
