What is an index fund, and which ones does WealthyBud track?
An index fund is a fund that buys the stocks in a published benchmark, like the S&P 500, instead of picking stocks by hand. WealthyBud tracks four broad-market index funds among its 28-ETF dataset: SPY, VOO and IVV, which all track the S&P 500, and VTI, which tracks the broader CRSP US Total Market index.
1. WealthyBud tracks 4 broad-market index funds: SPY, VOO, IVV, VTI
Among the 28 ETFs WealthyBud tracks, four are broad-market index funds — three S&P 500 trackers plus one total-market fund — as of 2026-07-10 (WealthyBud data · 28 ETFs).
2. SPY, launched in 1993, is the oldest of the four
SPY (SPDR S&P 500 ETF Trust) launched in 1993 and was among the first exchange-traded funds ever listed; VOO is the newest, launched in 2010 (WealthyBud data).
3. 3 of the 4 funds track the identical S&P 500 index
SPY, VOO and IVV each track the S&P 500, the same 500-company benchmark, while VTI tracks the CRSP US Total Market, which adds small- and mid-cap stocks the S&P 500 leaves out (WealthyBud data).
How do SPY, VOO, IVV and VTI expense ratios compare?
VOO, IVV and VTI tie for the lowest expense ratio among the four, at 0.03%, or $3.00 a year on a $10,000 position. SPY costs 0.09%, still cheap in absolute terms but more than 3 times the other three.
4. Cheapest: VOO, IVV and VTI tie at 0.03%
IVV, VOO, VTI all charge 0.03% — $3.00 a year on a $10,000 position — the lowest expense ratio among the four broad-market index funds WealthyBud tracks, as of 2026-07-10 (WealthyBud data).
5. SPY costs 0.09%, over 3× the other three
SPY (SPDR S&P 500 ETF Trust) charges 0.09%, or $9.45 a year per $10,000 — still a low fee, but more than three times VOO’s, IVV’s or VTI’s (WealthyBud data).
6. Fee gap to the priciest fund WealthyBud tracks: 0.46 points (16.3×)
The 0.03% charged by the cheapest index fund sits 0.46 percentage points below HYG, the priciest of all 28 ETFs WealthyBud tracks at 0.49% — a 16.3× difference (WealthyBud data · 2026-07-10).
| Ticker | Fund | Index tracked | Expense ratio | Cost per $10,000/yr |
|---|---|---|---|---|
| VOO | Vanguard S&P 500 ETF | S&P 500 | 0.03% | $3.00 |
| IVV | iShares Core S&P 500 ETF | S&P 500 | 0.03% | $3.00 |
| VTI | Vanguard Total Stock Market ETF | CRSP US Total Market | 0.03% | $3.00 |
| SPY | SPDR S&P 500 ETF Trust | S&P 500 | 0.09% | $9.45 |
How have SPY, VOO, IVV and VTI performed?
VTI led the four index funds on 1-year return, at 17.1%, while IVV trailed at 16.9% — a spread of only 0.19 percentage points. Over 5 years, the S&P 500 trackers annualized about 10.82%, versus 9.8% for the total-market fund VTI.
7. Best 1-year return: VTI at 17.1%
VTI (Vanguard Total Stock Market ETF) posted the strongest 1-year return among the four index funds, 17.1%, as of 2026-07-10 (WealthyBud data).
8. 3-year returns cluster within 0.29 points
3-year annualized returns range from 18.5% to 18.8% — a tight band, since all four hold overlapping large-cap U.S. stocks (WealthyBud data · 2026-07-10).
9. 5-year gap: VTI trails the S&P 500 trackers by 0.99 points
VTI annualized 9.8% over 5 years, versus a 10.82% average for SPY, VOO and IVV — a real, if modest, gap that reflects small- and mid-cap stocks lagging large caps over the period (WealthyBud data).
| Ticker | 1-yr return | 3-yr return (ann.) | 5-yr return (ann.) | Volatility (ann.) |
|---|---|---|---|---|
| VOO | 17.0% | 18.8% | 10.8% | 16.0% |
| IVV | 16.9% | 18.8% | 10.8% | 16.0% |
| VTI | 17.1% | 18.5% | 9.8% | 16.2% |
| SPY | 17.0% | 18.8% | 10.8% | 16.0% |

How closely do the S&P 500 index funds track each other?
SPY, VOO and IVV all track the identical S&P 500 index, and it shows: their 1-year returns sit within 0.10 percentage points of each other, and their 5-year annualized returns are within 0.01 points — essentially identical. Small differences come from fees and fund mechanics, not stock selection, since all three hold the same 500 companies.
10. 1-year return spread among SPY, VOO and IVV: 0.10 points
The three S&P 500 trackers returned between 16.9% and 17.0% over the trailing year — a 0.10-point spread explained almost entirely by their expense-ratio gap (WealthyBud data · 2026-07-10).
11. 5-year annualized spread: just 0.01 points
Over 5 years, SPY, VOO and IVV annualized between 10.8% and 10.8% — a 0.01-point spread, confirming that fund choice matters far less than fee choice among S&P 500 trackers (WealthyBud data).
12. Volatility is nearly identical too: a 0.04-point spread
Annualized volatility for SPY, VOO and IVV ranges from 16.0% to 16.0%, a 0.04-point spread — further evidence the three funds are near-interchangeable trackers of the same index (WealthyBud data · 2026-07-10).
How many active fund managers beat the S&P 500?
Most don’t, and the longer the horizon, the worse the odds get. 65.24% of active U.S. large-cap equity funds underperformed the S&P 500 over 1 year, rising to 89.50% over 15 years, according to S&P Dow Jones Indices’ SPIVA U.S. Year-End 2024 Scorecard, data as of December 31, 2024.
13. 1-year underperformance: 65.24%
65.24% of active U.S. large-cap funds underperformed the S&P 500 over the 1 year ending December 31, 2024, per S&P Dow Jones Indices’ SPIVA U.S. Year-End 2024 Scorecard.
14. 5-year underperformance: 76.26%
76.26% underperformed over the 5 years ending December 31, 2024, per the same SPIVA scorecard.
15. 10-year underperformance: 84.34%
84.34% underperformed over the 10 years ending December 31, 2024, per the same SPIVA scorecard.
16. 15-year underperformance: 89.50%
89.50% underperformed over 15 years, and no major U.S. equity or fixed-income category had a majority of active managers beat their benchmark, per the same SPIVA scorecard.
How much money is now in index funds versus actively managed funds?
Indexed mutual funds and ETFs held $21.82 trillion in combined net assets versus $18.75 trillion in actively managed funds as of May 2026 — a 53.8% share — and index funds pulled in far more new money that month too, per the Investment Company Institute.
17. Index funds hold $21.82 trillion, a 53.8% share
Indexed mutual funds and ETFs held $21.82 trillion in combined net assets as of May 2026, versus $18.75 trillion in actively managed funds — a 53.8% share of the combined $40.57 trillion market, per the Investment Company Institute’s Active and Index Investing release, published June 30, 2026.
18. Index funds pulled in 8.7× the new money active funds did in May 2026
Index funds had a net inflow of $96.47 billion in May 2026, versus $11.08 billion for active funds, per the same ICI release.
What this means for index-fund investors
Picking between S&P 500 trackers matters less than picking one at all. A 0.01-point 5-year spread among SPY, VOO and IVV means the fund barely moves your return; the expense ratio does.
Fees are a rounding error at the top, but not everywhere. The 0.46-point gap between the cheapest index fund and HYG, the priciest fund WealthyBud tracks, shows how much fee dispersion remains once you leave the core.
Total-market and S&P 500 exposure aren’t identical. VTI’s 0.99-point lag behind the S&P 500 trackers over 5 years shows small- and mid-cap stocks change results, even modestly.
The passive tide keeps rising. With 89.50% of active large-cap managers trailing the S&P 500 over 15 years, and index funds now outweighing active funds nationally, the case for a low-cost index core keeps getting easier to make.
