Missouri State Employees' Retirement System, Jefferson City, had a -19.1% return for the year ended June 30, according to a news release from the $6.2 billion system.
But the fund reported a $1 billion rebound since March.
The system's investment portfolio was up 4.2% for the five-year period ended June 30.
The retirement system outperformed 85% of other public pension plans with more than $1 billion in assets for the five-, 10- and 15-year periods ended June 30, according to the news release.
“We are glad to have this difficult year behind us and are pleased to be able to report investment income of approximately $1 billion since March of this year,” MOSERS Executive Director Gary Findlay said in the news release. “The MOSERS investment portfolio has admirably withstood a financial tsunami and is very well positioned to produce positive performance as economic conditions improve.”
