Summary
Said Haidar's flagship macro fund, Jupiter, run by Haidar Capital Management, lost 11.5% in October, according to an investor document seen by Bloomberg. The decline is the third double-digit monthly loss of 2026 for the highly leveraged strategy, which still holds year-to-date gains of 6.3%. Haidar Capital Management did not respond to a request for comment.

The fund's assets under management stood at $702 million at the end of September, a steep fall from a peak of around $5 billion in 2022. The strategy is known for outsized swings: it returned 193% in 2022 before posting losses of 43.4% and 32.7% in the two years that followed. Bloomberg reported that October's drawdown was well short of the worst on record, and that 15 months have been weaker since the firm launched in 1997.

The fund had gained almost 18% in September, driven by fixed income and commodities. The drivers of the October loss have not been disclosed. The month was difficult across the sector: a French bond selloff and renewed AI-related jitters weighed on markets, though Citadel and D.E. Shaw were among the few large managers to make money.
