March could be a good time for investors to reassess their portfolios.
Recent market volatility has created opportunities in certain sectors, while long-term structural trends continue to support others. Exchange traded funds (ETFs) offer a simple way to gain exposure to these opportunities without needing to pick individual winners.
Here are three of the best ASX ETFs to consider buying this month.

Betashares Global Defence ETF (ASX: ARMR)
The first ASX ETF to consider in March is the Betashares Global Defence ETF.
This fund focuses on companies involved in global defence and security, an area experiencing powerful structural tailwinds. Governments around the world are increasing defence budgets in response to rising geopolitical tensions and long-term security challenges.
The Betashares Global Defence ETF holds major defence contractors such as Lockheed Martin (NYSE: LMT), RTX Corporation (NYSE: RTX), Palantir Technologies Inc (NASDAQ: PLTR), and Northrop Grumman (NYSE: NOC). It also includes locally listed DroneShield Ltd (ASX: DRO).
These companies benefit from multi-year government contracts and sustained investment in military technology.
Unlike many sectors that are tied closely to economic cycles, defence spending is often driven by national security priorities. That creates a long-term demand backdrop that could support earnings growth across the industry.
This fund was recently recommended by analysts at Betashares.
Betashares Nasdaq 100 ETF (ASX: NDQ)
Another ASX ETF worth considering in March is the Betashares Nasdaq 100 ETF.
This fund tracks the Nasdaq 100 index, which includes many of the world's most influential technology and innovation-driven companies. However, the tech sector has recently experienced a selloff amid concerns about artificial intelligence (AI) disrupting parts of the software industry.
For long-term investors, that weakness may present an opportunity. The fund's holdings include companies such as Nvidia (NASDAQ: NVDA), Apple (NASDAQ: AAPL), and Microsoft (NASDAQ: MSFT), as well as globally recognised brands like Starbucks (NASDAQ: SBUX) and Costco (NASDAQ: COST).
These companies are deeply embedded in global digital infrastructure, consumer platforms, and emerging technologies. If the Nasdaq stabilises, this fund could benefit from renewed investor confidence.
VanEck China New Economy ETF (ASX: CNEW)
A final ASX ETF to consider this month is the VanEck China New Economy ETF.
This fund focuses on China's new economy sectors rather than traditional state-owned industries.
China's economy is undergoing a long-term transition toward technology, consumer services, and advanced manufacturing. ETFs like this provide exposure to that shift, giving investors access to businesses positioned to benefit from evolving domestic demand and technological innovation.
It was recently recommended by analysts at VanEck.
