The top stocks they held as of the end of December were Apple Inc., Amazon.com Inc., Tesla Inc., Facebook Inc. and Microsoft Corp., according to a survey by Apex Clearing of more than 730,000 U.S. investor accounts with an average age of 31 years and 3 months. The average account held about $2,300. While many of these companies often appear in the holdings of ESG funds, there is nothing to suggest millennials are buying them for that reason.
