AI ETFs areexchange-traded fundsthat invest in stocks of companies in the business of artificial intelligence, such as robotics, navigational systems, and automated machines and vehicles. AI ETFs may concentrate all of their holdings on AI stocks or they may include other technology-related stocks.

The world of artificial intelligence is still in its infancy but shows great promise for the future, which makes A.I. a compelling investment idea. The beginnings of A.I. can be seen in today with interactive, voice-powered personal assistants like Siri and Alexa,automated cars, and suggestive searches ideas in search engines like Google.

But the artificial intelligence of the future will be devices that can learn, attach meanings to new experiences, and get smarter and more aware, much like humans do. This will be the next phase of the digital age. The computers of tomorrow will be able to solve problems or find cures for diseases, making todays technology obsolete and opening doors for more growth in the A.I.sub-sector of technology.

Arguably, the best way to invest in AI technology is to invest in AIETFs. This is because, as with other concentrated sectors that are still in the infancy stage of the business cycle, it is inherently difficult and risky to attempt picking individual companies that will lead the industry. When you invest in an AI ETF, youll typically get exposure to dozens of stocks, which will reduce overall market risk by placing bets on more than just one stock.

Identifying the best AI ETFs on the investor level is a subjective exercise. For example, some investors may want a fund that focuses primarily on AI stocks, while others may want a tech stock fund that only allocates a portion of the funds assets to AI stocks. There are also funds that use artificial intelligence to choose the holdings.

Here is a summary of the basic types of artificial intelligence ETFs:

These are ETFs that invest specifically in companies involved in products or services related to artificial intelligence. These funds typically have 100 percent exposure to AI stocks.

These funds that have at least 25 percent of portfolio exposure to companies that use AI technology. Examples of such companies are Amazon (AMZN), Tesla  Motors (TSLA), Apple (AAPL) and Alphabet (GOOG, GOOGL).

These funds may not invest in AI stocks but the fund itself utilizes AI technology to select the individual securities to be held in the fund.

In no particular order, here are some of the best AI ETFs to buy now:
