After markets closed on Friday, S&P said Intel is out. It's being replaced, on Nov. 8, by rival chipmaker Nvidia, which has ballooned to become the world's second most-valuable public company, just a hair behind Apple as of Monday.

With the change, four of the tech industry's six trillion-dollar companies will be in the Dow, with internet giants Alphabet and Meta still on the outside. For those two companies, there are no obvious members to replace. Nvidia, on the other hand, recently leapfrogged Intel as the biggest chipmaker by revenue, creating a clear one-for-one swap opportunity.
