Palantir Technologies (PLTR), MicroStrategy (MSTR), and Axon Enterprise (AXON) joined the Nasdaq 100 Index on Monday, pushing out Super Micro Computer (SMCI), Moderna (MRNA), and Illumina (ILMN), the Nasdaq said Friday.

Shares of software maker Palantir dropped about 5% after the opening bell, while major Bitcoin holder MicroStrategy jumped more than 4%, and Taser weapon producer Axon dropped more than 3%. Notably, MicroStrategy may also be trading higher due its latest major Bitcoin buy. The largest corporate holder of the cryptocurrency acquired 15,350 bitcoins for approximately $1.5 billion, or $100,386 per bitcoin, according to an SEC filing Monday.

The Nasdaq 100, which contains the 100 largest non-financial sector companies in the Nasdaq Composite Index, is reconstituted annually in December and rebalanced quarterly to weight its constituents by market capitalization.

Because three companies are added to the Nasdaq 100, three previously listed companies have to be removed. Among those being removed, Supermicro could be delisted from the broader Nasdaq altogether if it fails to file its delayed annual report by a February deadline. The server maker has also hired an advisory firm to assist in raising capital, Bloomberg reported Friday. Supermicro shares fell about 5% Monday morning.
