Zweig-DiMenna Associates LLC

Zweig-DiMenna provides discretionary investment management primarily to several privately offered, unregistered pooled funds and may offer managed‑account services, though it currently reports no managed accounts. The Funds are domiciled both in the U.S. and internationally and are offered to qualified investors under each Fund’s governing documents.

The firm’s investment process emphasizes fundamental analysis for long and short equity selection, supported by proprietary quantitative models that inform overall market exposure and risk decisions, and it trades a wide range of instruments including swaps, options, futures and other derivatives. Zweig‑DiMenna also runs a discretionary global macro strategy that shifts exposure across equities, commodities (primarily via futures), currencies and fixed‑income instruments, and it employs prime brokers and futures commission merchants to implement those strategies.

What is notable relative to many peers is the combination of a core fundamental long/short equity program with a separate global macro sleeve that actively uses commodity futures and other derivative trading, giving the firm commodity‑trading characteristics not typical of pure equity managers. The brochure also discloses use of soft‑dollar research, formal capital‑introduction relationships with prime brokers, and a valuation committee that includes an independent member to review fair‑value determinations.
