If you have $500 to invest in the share market and have a preference for exchange-traded funds (ETFs), then it could be worth check out the three listed below.

These ETFs are very popular with investors and there is very good reason for that.

Here's what sort of stocks you will be buying with these funds:

BetaShares Asia Technology Tigers ETF (ASX: ASIA)

If you are feeling bullish on the growth of the Asian economy, then the BetaShares Asia Technology Tigers ETF could be worth considering.

That's because this ETF gives investors access to the best tech stocks in the Asian region but excluding Japan.

Many of these tech stocks are the region's equivalents of the West's biggest and best tech companies. They all appear very well-positioned for growth over the long term given Asia's growing middle class and its tech savvy population.

Among the ETF's holdings are e-commerce giant Alibaba, search engine provider Baidu, iPhone manufacturer Taiwan Semiconductor Manufacturing Company, and WeChat owner Tencent Holdings.

BetaShares Global Cybersecurity ETF (ASX: HACK)

Another ASX ETF that could be a good option for investors with $500 to invest is the BetaShares Global Cybersecurity ETF.

As its name suggests, this popular ETF provides investors with access to the global cybersecurity sector.

This could be a good place to park your money given that is predicted to grow materially over the next decade or two. In fact, Betashares highlights that the sector is estimated to be worth $2 trillion but only has 10% market penetration at present.

This sizeable market is being driven by the rising threat of cybercrime and more infrastructure moving to the cloud. The ETF's holdings include leaders in the industry such as Accenture, Cisco, Crowdstrike, and Palo Alto Networks.

BetaShares NASDAQ 100 ETF (ASX: NDQ)

A final ASX ETF for investors to consider for a $500 investment this month is the very popular BetaShares NASDAQ 100 ETF.

Among the fund's 100 holdings are many of the greatest stocks in the world. These are the global giants of our age and seemingly omnipresent in our lives. They make the phones in our pockets, the search engines we use countless times a day, the spreadsheets we use at work, the electric vehicles taking us from place to place, and the streaming services we watch in the evening.

The quality of its holdings means that this ASX ETF has smashed the market over the last decade. It would not be surprising to see it continue this trend over the next decade.
