I am a new user. i used the stock comparison tool to compare performance over last 10 years for vgslx, nly, voo, vmbs and bnd. the software showed me a nice 10 year chart which looked about right versus other analysis I had done. but when I downloaded chart I got a series of numbers which i did not understand. for example on vgslx starting 9/10/10 ((.0054), 9/30/15 (.767) and ending 10/1/25 ((2.1933). I assumed there numbers represent a cumulative return and calculated compound return based on that. Came up with numbers which differ from vanguard.

what I had hoped to see was a monthly return for each month.

do these numbers represent a cumulative return?

If so they may be inaccurate.

Hi William, welcome to the platform! And you got it right, the values you downloaded represent cumulative return from the beginning of the period. For VGSLX in your example, that’s from 0.54% on 9/10/10 to 219.33% on 10/1/25. What numbers did you get from Vanguard? I can check where the difference might come from.

For monthly returns, you can also go to the VGSLX page directly and scroll down to the Monthly Returns table. It shows both monthly and yearly numbers for that fund.


hope I am not being thick headed. I am not professional but have done similar calcs before with no problem.

If you have any manual on using site please direct me to it.

to make sure vgslx being a mutual fund might be causing problem I downloaded your numbers on vnq the sister etf. Again got difference v vanguard.

vanguard says 10 year return vnq ending 9/30/25 is 6.1%.

VNQ-Vanguard Real Estate ETF | Vanguard

your data begin 9/30/2015 (1.5192) end 9/30/25 (3.5569), accum return 2.0377, calculated 10 year compound return at 7.4% by taking 10th root of 2.0377.

Hmm, that math doesn't seem right. You first need to calculate the total return over ten years, and it’s not possible to just subtract one value from another. The correct calculation is: (1 + 3.5569) / (1 + 1.5192). That equals roughly 80.9%. Then take it to the power of one-tenth to annualize. That gives 6.1%, which matches the data provided by Vanguard exactly.

I need help on Investing! I need to invest 100K USD into US Etfs. I missed the April 25 slump in the market as I was out of country and not keeping track of the ETfs movement.

Now I need to invest, but the market is just going up and up! And I keep waiting for a dip- ?? Looks not coming!

Being a new investor- I would like to understand if the NAVs keep going up- Is it still Okay to invest- say will the Returns ie Performance over 10 years for an ETF with NAV of say 75 in April 25 be the same as the same ETF having an NAV of 110 today? Or will it do down ?

Thanks !
