The exchange-traded fund (ETF) Vanguard Australian Shares Index ETF (ASX: VAS) has lifted by 19.28% over the past 12 months.

The popular ASX ETF closed the session on Friday at $104.87 per unit, down 0.19% for the day.

The VAS ETF gives investors exposure to the 300 largest companies by market capitalisation on the Australian share market.

In other words, it seeks to track the performance of the S&P/ASX 300 Index (ASX: XKO) before fees.

In terms of share price growth, it is interesting to note that the VAS ETF is running pretty much neck-and-neck with peer ETFs that only track the benchmark S&P/ASX 200 Index (ASX: XJO).

Over the past 12 months, the iShares Core S&P/ASX 200 ETF (ASX: IOZ) has risen by 19.11% to $34.03 on Friday. The BetaShares Australia 200 ETF (ASX: A200) has increased by 19.64% to $141.39 on Friday.

So, it appears that the inclusion of those 100 small-cap shares ranked between 201 and 300 isn't giving the Vanguard Australian Shares Index ETF any particular advantage over IOZ or A200 right now.

Perhaps this may change next year, given falling interest rates are usually a tailwind for smaller growth companies, and it is widely expected that the Reserve Bank of Australia will begin cutting rates in 2025.

In reviewing the 12-month performance of the VAS ETF, we have identified which stocks have contributed the most growth over the period.
