In this article, we discuss the companies that made an appearance on the map for the first time and share October’s biggest winner and loser.

Newcomers on the map
Two companies made their map debut in October, being traded the most for the first time. While not a newcomer, there is also a third new name on our map. In case you missed it, Facebook Inc changed its name to Meta Platforms Inc on October 28th.
