For the October 22 session, Hedgeweek reports Bloomberg citing Goldman Sachs prime-brokerage data: fundamental long-short equity funds fell 1.4%, systematic long-short funds 1.3%, multistrategy platforms 1.9%, and technology, media and telecom-focused managers 2.7%.

The comparison is a look back at one session, not a claim about Tuesday’s close. In the reported sample, the multistrategy aggregate lost more than either long-short category; the category name did not buy a smaller number on that day. But these are prime-brokerage sample figures, not audited returns for the entire industry or four investable indices with a common construction.

The useful observation is breadth across named categories. Fundamental and systematic long-short were both negative, and the multistrategy aggregate was negative too. Without a position-level bridge, the figures do not establish that the managers owned the same trades or that crowding caused the result. Hedgeweek.
