Which is Better VTSAX or FZROX?

The answer depends on your goals and the brokerage you prefer to use.

To make it easier to decide, I’ll lay out the advantages of both of them.

VTSAX Advantages:

  • More Diversification
  • Vanguard Brokerage (Investor Owned)

FZROX Advantages:

  • No Cost
  • Higher Yield/Dividend


VTSAX Winner

My Winner: VTSAX

My winner is VTSAX, solely based on the fact that I love Vanguard.  Vanguard is a brokerage that is investor-owned.

Here is how Investopedia explains it:

“Vanguard has a fairly unique structure in terms of investment management companies. The company is owned by its funds. The company's different funds are then owned by the shareholders. Thus, the shareholders are the true owners of Vanguard.”

I believe both funds are excellent choices, but I have to give the edge to VTSAX because of Vanguard's commitment to its investors.

Vanguard has always been the first to offer very low-cost options for investing, and it was one of John Bogle's pioneering achievements.

As far as Fidelity, they have a responsibility to their shareholders to continue to increase their profits.

This means they are using FZROX as an industry “Loss Leader” to profit from you in some other way.

Also, there is no guarantee they will continue to offer the FZROX fund at a zero-percent fee.  They could increase that fee anytime, which wouldn't be surprising.

On the other hand, Vanguard has a long history of lowering fees for its investors.

That being said, choosing the fund that best fits your investment goals is essential.
