It should be noted that the "NASDAQ" among the three major U.S. stock indices usually refers to the "Nasdaq Composite Index", which has more than 3,000 components; the NASDAQ 100 Index is the "selected version" of the Nasdaq Composite Index, consisting of 100 components.
These 100 Stocks span across Technology, media, and Consumer sectors, characterized by high technology, high growth, and non-financial features. Currently popular "GFNZ100" tracking mostly follows the NASDAQ 100 Index, including QQQ, which has a size exceeding 320 billion dollars.
This also means that if a stock's weight in the NASDAQ 100 Index increases, it will receive passive buying from Funds, and vice versa. Regarding how to adjust the weight of this key Index, Nasdaq's rules are quite complex and have multiple interpretations.
Media analysis indicates that the weight of the NASDAQ 100 Index is generally determined by the relative Market Cap of its constituent Stocks. However, it is also constrained by several rules, such as when the total weight of all companies that account for 4.5% or more of the benchmark reaches or exceeds 48%, adjustments must be made.
The reason for this adjustment is that Broadcom has already increased by over 40% in December, triggering the 4.5% threshold. The last time this happened was in mid-2023, when the 'Seven Giants' made their mark, necessitating an adjustment of the Index weight.
Interactive Brokers Chief Strategy Officer Steve Sosnick commented, 'This is very technical. In some respects, the NASDAQ 100 Index has to do this because the largest Stocks in the Index have grown too astonishingly compared to the rest.'
As of Monday's close, the NASDAQ 100 Index has increased by approximately 28% year-to-date, but NVIDIA has surged over 182% during this period, Broadcom has risen nearly 111%, Tesla and Meta have increased over 70%, Amazon has grown by more than 48%, Google has risen nearly 40%, Apple has increased by 33%, and only Microsoft has not outperformed the Index.
