VFINX vs. VOO: A Detailed Comparison

As an investor, before committing to any investment choice, it’s crucial to understand the potential risks and rewards. 

In today’s discussion, we zero in on two popular S&P 500 investment vehicles from Vanguard - the Vanguard 500 Index Fund (VFINX) and the Vanguard S&P500 ETF (VOO). 

VFINX is no longer open to investors and has essentially been replaced by VFIAX, or the ETF equivalent, VOO. 

Which is Better - VFINX or VOO?

VFINX and VOO track the same index - the S&P 500. While VFINX is no longer open to investors, we will discuss its historical data. 

The main difference was in the expense ratio and minimum investment required. 

VOO has a lower expense ratio of 0.03% compared to VFINX’s 0.14%.

VFINX vs. VOO: Key Characteristics

Fundamentally, both VFINX and VOO provide broad exposure to large-cap U.S. equities by tracking the S&P 500. However, their structures differ.

VFINX was a mutual fund that only updated at the close of the market at its Net Assets Value (NAV). This makes mutual funds suitable for regular, systematic investing through techniques such as dollar-cost averaging.

On the other hand, VOO, an ETF, trades on an exchange like a stock at prices determined by market supply and demand throughout the day. ETFs may be better if you want the flexibility to adjust your position during trading hours.

VFINX vs. VOO: Performance Comparison

Performance is subjective and heavily influenced by market conditions and an investor’s individual strategy and time frame. 

Both VFINX and VOO aim to replicate the S&P 500 Index – so their performances in healthy market conditions should be quite similar. 

VFINX vs. VOO: Dividend Comparison

Both VFINX and VOO generate dividends from the underlying stocks making up the S&P 500. VFINX distributed dividends quarterly, and the yield hinged on the collective dividends of the fund’s holdings.

Similarly, VOO also pays dividends quarterly. Given they mirror the same index, the dividend yields for each should be similar, but payout details – dates and reinvestment options - can differ due to the structural nuances of mutual funds and ETFs.

VFINX vs. VOO: Expense Ratio Comparison

Expense ratios are a key variable in choosing between investment options. Lower expenses will usually lead to a greater portion of the returns landing in your pocket.

VFINX carries an expense ratio of 0.14% - which is fairly low compared to many mutual funds on the market. However, VOO has a smaller expense ratio of just 0.03%.

In this category, VOO clearly outperforms. Over time, this lower expense ratio could lead to a more significant compound effect on your investment returns.

VFINX vs. VOO: Risk-Adjusted Performance Comparison

Risk-adjusted performance measures the fund’s performance given its level of risk. Both VFINX and VOO, given their aim to match the S&P 500, should have roughly equivalent levels of risk and, consequently, similar risk-adjusted performance figures.

Remember, however, that, like all equity-based investments, they do carry a level of risk, and it’s vital to ensure this squares with your personal risk comfort zone.

VFINX vs. VOO: Which Should You Choose?

Choosing between VFINX and VOO should be dictated by your personal investment strategy, financial objectives, and comfort with the respective trading mechanics.

If you’re after specific intraday trading strategies or looking to minimize your expense ratio, VOO appears to be the optimal choice.

However, if you prefer a systematic investment approach where your purchase happens at the day-end NAV, or you’re already a VFINX investor, remaining with or choosing the VFINX could be a good decision.

Frequently Asked Questions (FAQs)

Is VFINX the Same as VOO?

While VFINX and VOO both aim to replicate the performance of the S&P 500, they are not the exact same. VFINX is a mutual fund, meaning it’s only tradeable at the end of the market day at the Net Asset Value (NAV) price. VOO, on the other hand, is an Exchange-Traded Fund (ETF), tradable throughout the trading day at market price.

Is VFINX a Good Investment?

If you believe in the power of the U.S. economy and value long-term, low-cost, diversified investments, then yes, VFINX could be a strong addition to your portfolio. As with any investment, it’s vital to ensure that it aligns with your financial goals and risk tolerance.

Is VFINX Closed to New Investors?

Yes, as of August 13, 2020, VFINX has been closed to new investors. Investors can instead consider Vanguard 500 Index Fund Admiral Shares (VFIAX).
