Brazilian hedge fund SPX Capital has lost its two main portfolio managers in Singapore as the firm continues to reshape its global operations following a period of weaker performance and investor outflows, according tp a report by Bloomberg.

The report cites regulatory filings as showing that Predee Anuvatnujotikul and Garret Mallal, who were among the Singapore operation’s senior portfolio managers, ceased to be associated with SPX Capital Management Singapore in June and August respectively.

The firm has also lost key trader Soh Yang Yao, who departed earlier this year and has since joined rival hedge fund Marshall Wace, the filings show.

William Bethlem, the former chief executive of SPX’s Singapore operation, has relocated to New York and is no longer listed as a financial representative of the local entity. Elsa Yachita assumed that position in January.

SPX Capital reportedly did not respond to requests for comment.

The departures come as SPX undertakes a broader review of its international business. Several long-serving portfolio managers have exited the firm in recent months, while the London operation was reportedly being wound down.

SPX managed more than $9bn as of 30 June, according to its website. The firm had previously grown to around $15.5bn, making it one of Brazil’s largest hedge fund managers.
