  • Ultra-low cost: Best ETFs charge 0.03% ($3/year per $10,000)

  • Simple: Buy once, hold for decades — no stock picking required
  • Proven performance: Index ETFs outperform 85%+ of active managers over 15 years

Frequently Asked Questions

Should I invest in one ETF or multiple?

A single broad-market ETF (VTI) is perfectly sufficient for many investors. Adding an international ETF (VXUS) and bond ETF (BND) creates a complete 3-fund portfolio covering the global market. More complex portfolios with 10+ ETFs often don't outperform the simple 3-fund approach after taxes and complexity.

What is the best time to buy ETFs?

For long-term investors, the best time is regularly (monthly or with each paycheck) regardless of market conditions — this is dollar-cost averaging. Trying to time the market (buy low, sell high) consistently is nearly impossible even for professionals. Time in the market beats timing the market.

The Main S&P 500 ETFs, Compared

Vanguard S&P 500 ETF (VOO)
Expense ratio: 0.03%  |  Holdings: 503 stocks  |  Best for: Vanguard brokerage customers
The world's first ETF to cross $1 trillion in assets (June 3, 2026) — commission-free and easiest to rebalance within a Vanguard account specifically.
iShares Core S&P 500 ETF (IVV)
Expense ratio: 0.03%  |  Holdings: 503 stocks  |  Best for: Investors at non-Vanguard brokerages
Nearly identical to VOO — same index, same expense ratio, same daily liquidity. The practical choice often comes down to which brokerage you use.
SPDR S&P 500 ETF Trust (SPY)
Expense ratio: 0.09%  |  Holdings: 503 stocks  |  Best for: Active traders needing maximum liquidity
The original and most heavily-traded S&P 500 ETF, valued by active traders for tight bid-ask spreads even though its expense ratio is triple VOO/IVV's.

VOO vs IVV vs SPY: Which to Actually Choose

For a long-term, buy-and-hold investor, VOO and IVV are functionally interchangeable — same underlying index, same rock-bottom 0.03% fee, same daily liquidity for virtually any retail investor's needs. The practical tiebreaker is usually which brokerage you already use: Vanguard customers get slight rebalancing convenience from VOO, everyone else can use IVV with no meaningful difference. SPY's higher fee only makes sense for active traders who specifically need its exceptional liquidity and tight spreads for frequent trading, not for buy-and-hold investors.
