Vanguard fund question, check my assumption

[NoStacheOhio]

This should be fairly simple. I have access to a couple Vanguard funds in my 403b, but not VTSAX.

Does 75% VINIX/25% VIEIX approximate VTSAX?

Thx

My 401k is the same. When I checked it was 80/20 S&P 500 and extended market = VTSAX. But your numbers are probably as accurate as mine.

For the record, you're correct. 80/20 is closer to a total market index.

Great tool! Will also need it as my new 401k doesn't have VTSAX as well. How does one compare this "mix" with an existing index or another mix? I made a mock up 80/20 based on the above two, but I don't see the "compare" button. Thanks!

I just opened another tab and plugged in 100% VTSAX, then went back and forth to compare the two. There's probably a better way to do this.

Yeah you'd think a better way exists, but I haven't found one =/. I too just use the 2 tab method.

Haha oops.

How do you compare them? What numbers are particularly important? I guess, at least % in the CAP-GROWTH for both mix and VTSAX. What else? Would be great to have an overlaid graph of two portfolios

I was looking at the sector allocations mostly.

Yup. I look at sectors and also the 9 box - the 3x3 box of valuation and size.
And for comparing international funds, I also look at countries.

Thanks!
to OP - sorry for hijacking your thread - trying to minimize servers load :)

I have following Vanguard options: VIMAX, VFIAX, VSMAX, VTIAX.
Looking at smth like 1) 70/15/15 VFIAX/VIMAX/VSMAX or 2) up to 10% VTIAX and 65% VFIAX.
Suggestions?

Funny story: My wife had the choice of VFINX and VEXMX in her tax-deferred account. I read that VEXMX was a "completion index" so I put her 50% in each. 15 years later, I find out it should have been 80/20...lucky for us VEXMX outperformed by 3% a year :-)

Hijack away! I don't mind.

Option one seems like you're leaning toward mid and small caps. If you want a market cap allocation, it looks like you need 75-80% large caps.

Edit: Just found this, which may be helpful https://www.bogleheads.org/wiki/Approximating_total_stock_market

It appears 81/4/15 gives you total market index for Vanguard. They're different symbols, but I think it's just the share class.
