Nasdaq is proposing a reform that would significantly change how large companies are added to its most important index. The initiative aims to implement a fundamentally different 3-rule, drastically reducing the waiting times for inclusion in the Nasdaq 100.

According to reports from Odaily, the proposal would allow new listings of major companies to join the index after only 15 trading days, instead of the current requirement to wait at least three months. This regulatory change represents a strategic shift for the exchange, which seeks to keep its index more dynamic and reflective of current market conditions.

The amendment would reflect Nasdaq's effort to streamline its administrative processes and ensure that its index more quickly captures the performance of recently listed companies. If approved, this 3-month versus 15-day rule could set a new standard in the stock industry for the accelerated inclusion of large-cap companies.
