Dec 12 (Reuters) - Bitcoin hoarding giant Strategy MSTR.O clung to its place in the Nasdaq 100 .NDX on Friday, continuing its year-long stint in the benchmark at a time where analysts have raised questions over its business model.
Some market watchers have suggested Strategy's pioneering business model of buying-and-holding bitcoin, which has spawned dozens of copycats, more closely resembles that of an investment fund.
Concerns have grown over the sustainability of crypto treasury companies, whose shares have proved extremely sensitive to bitcoin's gyrations.
Nasdaq said Biogen BIIB.O, CDW Corporation CDW.O, Globalfoundries GFS.O, Lululemon Athletica LULU.O, On Semiconductor ON.O and Trade Desk TTD.O were removed from the tech-heavy exchange's benchmark index.
New entrants included Alnylam Pharmaceuticals ALNY.O, Ferrovial FERF.AS, Insmed INSM.O, Monolithic Power Systems MPWR.O, Seagate Technology STX.O and Western Digital WDC.O.
Strategy started out as software company, MicroStrategy, but pivoted to bitcoin investing in 2020. It was included in the Nasdaq 100 last December under the index's technology sub-category.
Global index provider MSCI MSCI.N has also raised concerns about the presence of digital-asset treasury companies in its benchmarks. MSCI is due to decide in January whether to exclude Strategy and similar companies.
The Nasdaq changes are expected to take effect on December 22. The Nasdaq 100 index tracks the largest non-financial companies by market capitalization listed on the exchange.
