Data shows that Said Haidar’s hedge fund posted its biggest monthly gain in two and a half years in December, successfully avoiding an annual loss for the third consecutive year. For the macro trader, this marks a dramatic turnaround. Records show that his Haidar Jupiter fund is estimated to have risen 20.3% last month, the highest since June 2023, bringing the full-year return to 6.8%. The fund had lost 32.7% in 2024 and 43.4% the previous year, giving back some of the gains from its 531% rise over the preceding three years. The specific reasons for the December surge remain unclear, but filings show that as the month began, the hedge fund’s largest exposure was concentrated in equities, followed by credit and fixed income. Haidar is known for its highly leveraged macro trades and high-volatility strategies that generate frequent double-digit swings, and its performance has been highly volatile in recent years. Another filing shows that its assets under management have shrunk from approximately $5 billion in 2022 to $481 million as of the end of November last year.
