Commonwealth Bank of Australia (ASX: CBA) has revealed the three most traded ASX exchange-traded funds (ETFs) among shares investors using the CommSec trading platform this year.

Two of the three most popular ASX ETFs share a common thread in that they track international shares, particularly United States shares.

This reflects a broader trend identified by the ASX and Vanguard earlier this year.

ETFs holding international shares have attracted more investment from Aussie investors this year due to the outperformance of the S&P 500 Index (SP: .INX) compared to the S&P/ASX 200 Index (ASX: XJO).

In the year to date, the S&P 500 is up 27.57% compared to a 9.28% rise for the ASX 200 (this excludes dividend returns, which are typically about 4% per year).

Let's take a look at the three ASX ETFs that were the most popular among CommSec clients this year.
