The assessment is based on strong, direct evidence from a highly authoritative primary source. The summary for the official Nasdaq page listing the Nasdaq-100 constituents explicitly states that it includes 'Strategy Inc Common Stock Class A,' directly confirming its status as a member of the index. This provides the most compelling evidence in support of the statement. Furthermore, other high-authority sources, such as the official press release and a news report on the annual reconstitution, establish the context in which a company would be 'retained'. While several other sources show the word 'strategy' used in a marketing or generic business context, they are of low or no relevance and do not contradict the primary evidence. They simply represent noise. The core of the claim—that an entity named 'Strategy' is a constituent of the Nasdaq 100—is directly supported by the most relevant source provided.
