Valdor Technology International Inc Stock Forum

i like VTI or VOO. No individual stock will beat their stability
$Valdor Technology International Inc(VTI.CA)$ $Vanguard S&P 500 ETF(VOO.US)$

I was thinking $Valdor Technology International Inc(VTI.CA)$ and a dividend ETF with dividends reinvested.
What are your recommendations for their situation?

I would also like to know why $VANGUARD INVESTMENTS CANADA INC S&P 500 INDEX ETF(VFV.CA)$ is the preferred choice over $Valdor Technology International Inc(VTI.CA)$ .

Wifes portfolio is $VANGUARD INVESTMENTS CANADA INC S&P 500 INDEX ETF(VFV.CA)$ , $Valdor Technology International Inc(VTI.CA)$ , $ISHARES S&P/TSX 60 INDEX ETF UNIT(XIU.CA)$ and $VANGUARD FTSE CANADA INDEX ETF TRUST UNIT(VCE.CA)$ . It was handily beating my dividend stocks...at least until I realised that her total included our sons' RESP. 
We put the same into each of our accounts per pay, but pay separately into the RESP. 
Now they have similar returns.

If you wanna start investing then you can just pick one and start.
1️⃣ Vanguard S&P 500 ETF ( $Vanguard S&P 500 ETF(VOO.US)$ ):  Vanguards’ S&P 500 index fund tracks the S&P 500,
Expense ratio of just 0.03%.
2️⃣ Fidelity ZERO Large Cap Index Fund (): If you don’t want the fees at all then Fidelity’s S&P 500 tracker, promises the expense ratio of 0.00% (no fees!). My personal favorite.
3️⃣ Schwab U.S. Broad Market Index ETF ( $Schwab US Broad Market ETF(SCHB.US)$ )...
