Frequently Asked Questions

Is SPY or VOO better?

For most long-term investors, VOO is better due to its lower expense ratio (0.03% vs 0.09%). SPY is better for traders who need maximum liquidity or trade options frequently.

Why is SPY more expensive than VOO?

SPY was launched in 1993 as a Unit Investment Trust, which has structural constraints that prevent dividend reinvestment and lead to slightly higher costs. VOO, launched in 2010, uses a more modern ETF structure.

Do SPY and VOO have the same returns?

Yes, both track the S&P 500 index. The only difference in returns comes from the expense ratio — VOO will outperform SPY by approximately 0.06% annually due to lower fees.

Should I sell SPY and buy VOO?

If you're in a taxable account, the tax implications of selling may outweigh the fee savings. In a tax-advantaged account (IRA/401k), switching to VOO can make sense for the lower fees.
