Vanguard has an ETF version of VTSAX, the Vanguard Total Stock Market ETF (VTI).  VTSAX is an admiral index fund with a $3,000 minimum initial investment and a lower expense ratio than non-admiral funds.

The fund invests in various sectors and has a low expense ratio.


VOO Performance

Vanguard’s VOO aims to have the same performance returns as the S&P 500 index.  Therefore, VOO and the S&P 500 should always overlap.

Here is VOO and the S&P 500 Index performance chart:

No Minimum Investment

VOO is an exchange-traded fund which means there is NO minimum investment.  Instead, investors looking to buy fractional shares can invest in Vanguard 500 Index Fund Admiral Shares (VFIAX), the equivalent index fund.

Usually, fractional shares are not available for ETFs except with M1 Finance.  (Get $100 When You Use This Link)

Buying fractional shares allows you to maximize your investment.  You no longer have to keep your money idle until you have enough to purchase a full share.

VTSAX Profile

  • Fund Inception: 2000
  • Tracks the CRSP US Total Market Index
  • Expense Ratio: 0.04%
  • Vanguard Fund
  • Minimum Initial Investment: $3,000
  • Number Of Stocks: 3,535
  • Equivalent ETF (VTI)

Vanguard Total Stock Market Index Fund Admiral Shares (VTSAX) represents close to 100% of the U.S. equity market that is publicly traded.  It also tracks the CRSP U.S. Total Market Index.

Vanguard’s VTSAX has an expense ratio of 0.04%.

This notably implies that the fund has limited exposure to several international stocks.

However, this does not affect the companies represented in the fund.  These stocks have a significant international presence.


VTSAX Performance

Vanguard Total Stock Market Index Fund Admiral Shares (VTSAX) is popular for so many reasons, of which consistent returns are a major part.

Its risk level is similar to that of the S&P 500.

VTSAX Holdings

Vanguard’s VTSAX comprises Apple, Microsoft, Google, Amazon, and Tesla, providing exposure to over 3,500 stocks.

Here are the top 10 holdings for VTSAX:

Major sectors in the index include:

  • Healthcare
  • Technology
  • Consumer Services
  • Financials
  • Industrials

The top 10 holdings make up 25% of its total net assets.


$3,000 Minimum Investment

VTSAX used to have a minimum initial investment of $10,000, but this changed to $3,000 in 2018.  Once you save up the $3,000 minimum, each investment after that does not have a minimum.

You can avoid this minimum investment threshold through retirement account contributions or investing in Vanguard Total Stock Market ETF (VTI).


Index Funds vs Exchange Traded Funds (ETFs)

Exchange-traded funds (ETFs) are usually a more accessible option for new investors since they don’t have a minimum investment.  In comparison, if you can afford to invest more than the minimum, it’s usually a better option to choose admiral index funds because they have a lower expense ratio.

In this case, the expense ratio is almost the same, only differing by 0.01%.

ETFs are also available to trade at any time the market is open.  Index funds are bought after the market closes and the price settles.  Depending on your views, this can be a good or bad thing.

For long-term investors, the ability to trade anytime in the day is not a benefit.  Instead, it can encourage market timing and frequent trading.

An index fund might be a better option if you have these tendencies.

Lastly, if you prefer to have every penny invested, then you will like that Index funds offer fractional share buying.

On the contrary, ETFs must be bought one full share at a time.  That can sometimes lead to uninvested money while waiting for your next contribution.

This is more of a preference since I don’t think it will significantly affect your returns.


Which is Better VTSAX or VOO?

VTSAX and VOO are very similar investments.  Since VTSAX is an admiral share fund, it offers very low expense ratios and the ability to purchase fractional shares.

VTSAX also offers more diversification since it holds about 7 times more stocks.

VOO did slightly outperform VTSAX.  However, past performance isn’t an indication of future returns.

For those reasons, I would give the advantage to VTSAX over VOO.
