The best technology stocks to buy are targeting disruptive innovation trends that include deep learning, streaming media, electric vehicles, automation and 3D printing, according to a new study by New-York-based technology investment firm ARK Invest.

ARK’s “Big Ideas 2020” report focuses on key trends driving growth rather than recommending specific stocks, but I reached out to seasoned market followers who track key technologies closely and they revealed their favorite companies in each niche. The result is an array of the best technology stocks to buy that vary from established giants involved in several trends to smaller specialists focused on just one.

Six additional “Big Ideas” in the report feature autonomous ride-hailing, aerial drones, next-generation DNA sequencing, biotech research and development (R&D) efficiency, digital wallets and bitcoin. Investors willing to commit funds to these promising technologies should consider potential returns, their own risk tolerance and whether they also want dividend-paying stocks before deciding which ones to buy.
