But it can also make the decision feel harder.

With a larger sum, investors may not want to put everything into one narrow idea. A better approach could be to build around a mix of broad global exposure, proven technology leaders, and a focused long-term growth theme.

With that in mind, here are three ASX exchange traded funds (ETFs) that could be worth considering.

Betashares Global Shares ETF (ASX: BGBL)

The first ASX ETF to consider is the Betashares Global Shares ETF.

This fund gives investors exposure to a large basket of global shares across developed markets.

That means it is not tied to the fortunes of the Australian economy. Instead, investors can gain exposure to global companies across technology, financials, healthcare, industrials, consumer goods, and communications.

Major holdings include Nvidia (NASDAQ: NVDA) and Apple (NASDAQ: AAPL).

I think this ASX ETF could work well as a foundation holding because it offers significant diversification in one trade. It was recently recommended by the team at Betashares.

Betashares Nasdaq 100 ETF (ASX: NDQ)

Another ASX ETF to consider is the Betashares Nasdaq 100 ETF.

This fund is more growth-focused than the BGBL ETF. It gives investors exposure to 100 of the largest non-financial companies listed on the Nasdaq exchange.

These companies are involved in some of the biggest shifts in the global economy, including artificial intelligence, cloud computing, digital advertising, software, ecommerce, streaming, chips, and consumer technology.

Holdings include Microsoft (NASDAQ: MSFT) and Amazon (NASDAQ: AMZN).

This ASX ETF can be volatile because it has a heavy tilt toward technology and growth shares. But for investors with a long-term view, it provides exposure to companies that are shaping how people work, shop, communicate, and use technology.

VanEck Global Semiconductor ETF (ASX: SMHG)

A final ASX ETF that could be worth a closer look is the VanEck Global Semiconductor ETF.

This is the most targeted option of the three. The fund gives investors exposure to companies involved in semiconductors and semiconductor equipment.

That makes it a way to invest in the chips behind artificial intelligence, cloud computing, data centres, electric vehicles, smartphones, automation, and advanced manufacturing.

Holdings include Taiwan Semiconductor Manufacturing (NYSE: TSM) and Nvidia.

This is unlikely to be a smooth ride. Semiconductor shares can be cyclical and sentiment can move quickly.

But the long-term theme is powerful. The modern economy needs more computing power, not less, and semiconductors sit at the centre of that demand.

This fund was recently recommended by the team at VanEck.
