NASDAQ-100 update in 2022

The index is rebalanced annually in December. If at any point an issuer becomes ineligible – for example, in case of a merger or acquisition, delisting from the NASDAQ, or bankruptcy – its stock is removed from the index and replaced with another company from the waiting list without waiting until the end of the year.

The NASDAQ-100 comprised 101 firms in 2022 with Constellation Energy Corp (NASDAQ: CEG) splitting from Exelon Corporation (NASDAQ: EXC) and remaining on the index. Seven issuers – VeriSign Inc. (NASDAQ: VRSN), Skyworks Solutions Inc. (NASDAQ: SWKS), Splunk Inc. (NASDAQ: SPLK), Baidu Inc. (NASDAQ: BIDU), Match Group Inc. (NASDAQ: MTCH), DocuSign Inc. (NASDAQ: DOCU) and NetEase Inc. (NASDAQ: NTES) – left the list on 19 December.

They were replaced by six companies – CoStar Group Inc. (NASDAQ: CSGP), Rivian Automotive Inc. (NASDAQ: RIVN), Warner Bros. Discovery Inc. (NASDAQ: WBD), GlobalFoundries Inc. (NASDAQ: GFS), Baker Hughes Company (NASDAQ: BKR) and Diamondback Energy Inc. (NASDAQ: FANG).

The cumulative return for 2022 of the above corporations was -46%, while the index return reached -31%.


From 2018 to 2021 inclusive, a quantitative easing programme was in place during which the US interest rate was lowered from 2.5% to 0.25%. This was a favourable business environment that, even during the COVID-19 pandemic, allowed stocks of firms added to the index to show positive returns.

However, in 2022, the Federal Reserve System (FED) began to raise the interest rate and launched a quantitative tightening programme. As it turned out, these decisions had a more negative impact on stock prices than the pandemic.

Of the periods discussed above, only in 2019 were the returns on investments in the newcomers to the index higher than the ones on the NASDAQ-100. In addition, the level of return on each of the stocks listed was not correlated with the index or the other stocks on the list.

It can be concluded that the inclusion of companies in the index does not have a strong impact on their stock price. Based on data from the last four years, it can be assumed that the Fed policy has been a key factor affecting stock prices.
