1. History of NDX

The Nasdaq-100 Index was established in January 1985. Initially, it included only 100 stocks, but over the years, it has evolved significantly. The index was designed to provide investors with a benchmark for the performance of non-financial companies listed on the Nasdaq Stock Market. One of the most significant milestones in its history was the dot-com boom of the late 1990s, which propelled many technology companies into the public eye.

As technology advanced and more companies entered the market, the NDX saw substantial fluctuations. The index hit its peak during the dot-com bubble, followed by a sharp decline in the early 2000s. Despite these ups and downs, the NDX has continued to attract investor interest due to its heavy concentration in technology stocks.

2. Calculation Methodology

The Nasdaq-100 Index is a modified capitalization-weighted index. This means that each company's weight in the index is proportional to its market capitalization, but there are adjustments to prevent any single company from dominating the index. The formula for calculating the NDX is as follows:

• Determine the market capitalization of each company in the index.
• Apply a modification factor to limit the weight of any single stock to a maximum percentage.
• Calculate the total value of the index based on these adjusted weights.

Every quarter, the index undergoes a rebalancing to ensure that it accurately represents the market. This rebalancing involves adding new companies that meet the criteria and removing those that no longer qualify.
