Top 10 holdings of VOO only makes up a quarter of the total asset compared to almost half of the total asset for VGT. From this we can gather that performance of VGT could hinge a lot on the top 10 holdings.

Another thing that I noticed with VGT is that companies such as Amazon, Facebook and Google are not included in the ETF. Amazon is classified as Internet & Direct Marketing Retail and Google and Facebook are under Interactive Media & Services. This means they do not fall under any the sub categories in VGT as seen below.


With VOO, you get diversification across the different sectors including Information Technology.

The 10 years annualized return for VOO and VGT are 20.15% and 13.87% respectively. These are rather decent returns for funds that are passively managed.


Based on the past performance, VGT (Vanguard Information Technology ETF) is the one to pick with a portfolio growth of almost doubled more than VOO.

It also perform better in terms of the annual returns. There has been no negative annual returns in the last 10 years.

That said, I was rather surprised to find that companies like Amazon, Facebook and Google aren’t in the VGT list. But then, we can see that this didn’t prevent VGT from outperforming VOO.

I’m leaning toward VGT here, simply because of the performance, and I do believe that technology sector will continue to outperform in the future, compared to other sectors.

However, if you want a more diversified portfolio, then stick with VOO. You can’t go wrong with a 10 year annualized return of 13.87% too.

As always, remember that Past Performance is No Guarantee of Future Results.
