The most relevant and authoritative evidence comes from a Bloomberg report citing Goldman Sachs analysis that hedge funds have rapidly increased short positions in US equities, with specific emphasis on the technology/software sector. The report directly mentions the magnitude of the short exposure as 3.8% of US software stocks and indicates this level is the highest on record. Additional support comes from Reuters market coverage that aligns with the narrative of heightened hedge fund shorting in tech/software stocks, though it provides less precise statistical confirmation. Other sources provide broader market context or partial mentions of exposure to software firms without contradicting the claim. No primary source reviewed presents data contradicting the statement, and the Bloomberg/Goldman Sachs dataset is a credible, high-authority basis for these specific figures. Given the consistency in reporting across high-relevance sources, and the absence of conflicting evidence, it is highly probable that the statement is accurate.
