Lessen the weighting of those recent tech highflyers and then adding the weight of those other 93 or so companies, some more than others. So certain equities could see a bump up as a result of their newfound heavier weighting.
From Real Money/The Street:
How Has This Happened?
The story behind
this almost isolated selloff is simply this: During the first half of 2023, as the headline equity indexes rallied for the most part on poor or narrow market breadth, the mega-cap tech names led the way higher. These stocks rallied almost in isolation and benefited to a far greater degree than did the broader US equity market at large over the past six months.
These few stocks have come to dominate by weighting the tech-centric Nasdaq 100 Index. That Nasdaq 100 is up 37.53% year to date versus the Nasdaq Composite's 30.76%. The S&P 500, for perspective, is up 14.85% this year.
The Rules
Nasdaq rules state that if all stocks weighing 4.5% or more individually upon the index exceed in aggregate, more than a 48% weighting upon the Nasdaq 100 index, the index must then rebalance. The rules states that this aggregate rebalancing must reset this weighting at 40%. Six of these seven mega-cap stocks weigh at least 4.5% upon the Nasdaq 100... Microsoft (12.9%) Apple (12.5%), Alphabet (7.4%), Nvidia (7%), Amazon (6.9%), and Tesla (4.5%). Meta Platforms does not weigh 4.5%, and META was the one stock of the seven that gained on Monday. The other six sold off.
