Minimum Investment – Tie
Both SPY and VTI require a minimum investment of $1.00. Since these are both ETFs, they can be traded on fractional shares, allowing for even the smallest investment. In addition, SPY and VTI are well-known ETFs that are easily accessible and should be easy to invest in.
Expense Ratio – VTI
VTI has an expense ratio of 0.03%, which is cheaper than SPY. SPY has an expense ratio of 0.09%, which is 3 times higher than the VTI expense ratio. Overall, both ETFs have relatively low expense ratios compared to the industry average of 0.25%.
Trading and Liquidity – Tie
VTI and SPY have the same trading and liquidity characteristics since they are both ETFs.
Investors can buy and sell ETFs throughout the day at any time during market hours. This is not the case with mutual funds, which are only traded at the end of the day based on Net Asset Value (NAV).
ETFs’ trading flexibility doesn’t come without drawbacks, though—they typically trade at prices slightly different from their NAV. This difference is called a bid-ask spread.
ETFs offer an advantage to investors who trade daily or change positions frequently. Since they can trade throughout the day, whereas mutual funds, you have to wait until the day is closed.
Tax Efficiency – Tie
When comparing two different investment options, it’s essential to consider the tax implications and not only the returns they generate. The tax implications of an investment can have a significant impact on which investment generates higher after-tax returns.
Generally, ETFs will have a slight edge from a tax efficiency perspective. ETFs tend to distribute comparatively fewer capital gains to shareholders – these same gains are simply more challenging to manage efficiently from a mutual fund.
Overall, SPY and VTI are considered to have the same level of tax efficiency.
Tax Loss Harvesting – Tie
As ETFs, both SPY and VTI have the same rules and regulations.
Tax-loss harvesting is a strategy that involves selling investments at a loss to offset gains (and up to $3,000 in ordinary income). Tax-loss harvesting only matters in taxable investment accounts since you aren’t taxed on capital gains in tax-deferred accounts.
While this strategy can be implemented using any type of investment (stocks, ETFs, mutual funds, or other property), mutual funds have an advantage because of how they are traded.
When you sell an ETF, you’ll have to wait for the funds to settle before reinvesting the proceeds. This wait, commonly referred to as T+2, may be one or two days before you have access to the funds.
If you prefer the tax-loss harvesting rules of a mutual fund, opting for a similar indexed mutual fund might be a better option.
