Multiple authoritative and highly relevant financial news sources report that Goldman Sachs Prime Services trading desk data indicates global hedge funds purchased a record amount of Asian equities during a five-day period. These reports are based on proprietary institutional trading metrics and are presented as factual data points rather than speculation. Reuters and Yahoo Finance both cite this information directly, with consistency across independent outlets, suggesting the claim is well-substantiated. The historical context—comparing the buying volume to past activity—supports the phrase 'record amount.' Furthermore, data from official exchange statistics aligns with the notion of unusually high cross-border flows, reinforcing credibility. No reputable sources in the provided materials contradict the claim, and the minor variations in phrasing ('largest net buying since 2016' or 'record amount') still point to extraordinary, record-level activity. Given the high authority of the sources, direct attribution to Goldman Sachs' data, and lack of conflicting evidence, the probability that the statement is true is high.
